insulin glargine, lixisenatide

Insulins and Analogs and Incretin Mimetic Combinations

Injectable Administration

Insulin glargine; lixisenatide is administered by subcutaneous injection only. Do NOT administer intravenously, intramuscularly, or in an insulin infusion pump.
Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. Do not use injections that are unusually viscous, cloudy, discolored, or contain particulate matter. This injection is clear and colorless.
 
Insulin Pens:
Insulin glargine; lixisenatide is available as a prefilled pen containing 300 units of insulin glargine and 99 mcg of lixisenatide.
This product is administered as dose units. One dose unit contains 1 unit of insulin glargine and 0.33 mcg of lixisenatide.
Insulin pens should never be shared among patients. Even if the disposable needle is changed, sharing may result in transmission of hepatitis viruses, HIV, or other blood-borne pathogens. Do not share pens among multiple patients in an inpatient setting; use multidose vials instead, if available, or, reserve the use of any pen for 1 patient only.
Ensure that the patient knows how to use the type of pen needles being dispensed.
For standard pen needles with both an outer cover and an inner needle cover, remove both covers before use.
For the safety pen needle, remove only the outer cover; the fixed inner needle shield remains in place.

Subcutaneous Administration

Insulin glargine; lixisenatide Pre-filled Pen:
Administer once daily within the hour prior to the first meal of the day. Do not split the dose.
Subcutaneous injections of insulin glargine; lixisenatide are made into the anterior and lateral aspects of the thigh, the upper arm, or the abdomen.
The needle should remain in the skin for at least 10 seconds to ensure complete delivery of the selected dose (the patient should slowly count to 10).
Rotate injection sites within the same region with each injection to prevent lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis. During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring.
The pen delivers doses from 15 to 60 dose units with each injection.
The pen dials doses in 1 unit increments.
Do not dilute or mix with any other insulin or solution.
Do not administer with other GLP-1 receptor agonists.
Double-check the pen label to ensure proper product selection and the dosage in the injection device prior to administration. Prime the device prior to each injection to ensure accurate dosing.
Missed dose: Resume as prescribed with the next scheduled dose; do not administer an extra dose or increase the dose.
Storage of opened pen: After the first use, store the pen at room temperature below 25 degrees C (77 degrees F) for up to 28 days; do NOT refrigerate. Do not expose to excessive heat or direct light. Discard the pen 28 days after first in use, even if the pen still contains medicine.

Hepatic Impairment

The effect of hepatic impairment on the pharmacokinetics of insulin glargine; lixisenatide has not been studied. Frequent glucose monitoring and dose adjustment may be necessary in patients with hepatic impairment.

Renal Impairment

eGFR 60 to 89 mL/min/1.73 m2: No dosage adjustment needed. Monitor closely for adverse reactions, especially hypoglycemia, nausea, and vomiting, and for changes in renal function.
eGFR 30 to 59 mL/min/1.73 m2: No dosage adjustment needed. Monitor closely for adverse reactions, especially hypoglycemia, nausea, and vomiting, and for changes in renal function. Dehydration and acute renal failure and worsening of chronic renal failure may occur in these patients.
eGFR 15 to 29 mL/min/1.73 m2: Clinical experience is limited; lixisenatide exposure is higher in these patients. Monitor closely for adverse reactions, especially hypoglycemia, nausea, and vomiting, and for changes in renal function. Dehydration and acute renal failure and worsening of chronic renal failure may occur in these patients.
eGFR less than 15 mL/min/1.73 m2: Do not use.

Acebutolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Bisoprolol; Hydrochlorothiazide, HCTZ: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Dasiglucagon: (Minor) Caution should be exercised when glucagon is used as a diagnostic aid for radiologic examination in patients taking insulin. Insulin reacts antagonistically towards glucagon. Monitor the patient receiving glucagon for a diagnostic procedure for the desired clinical effects. There is no concern when glucagon is used to treat severe hypoglycemia. If a patient receives glucagon due to severe hypoglycemia by a family member or caregiver, they should alert their health care provider so that insulin treatment may be adjusted, if needed.
Deflazacort: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Desloratadine; Pseudoephedrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion.

Diazoxide: (Minor) Diazoxide, when administered intravenously or orally, produces a prompt dose-related increase in blood glucose level, due primarily to an inhibition of insulin release from the pancreas, and also to an extrapancreatic effect. The hyperglycemic effect begins within an hour and generally lasts no more than 8 hours in the presence of normal renal function. The hyperglycemic effect of diazoxide is expected to be antagonized by certain antidiabetic agents (e.g., insulin or a sulfonylurea). Blood glucose should be closely monitored.
Dienogest; Estradiol valerate: (Moderate) Separate the administration times of lixisenatide and estrogen and progestin containing oral contraceptives. Advise patients to take estrogen and progestin containing oral contraceptives at least 1 hour before or 11 hours after lixisenatide.

Digoxin: (Moderate) Concomitant administration of lixisenatide 20 mcg and digoxin 0.25 mg (at steady state) delayed digoxin Tmax by approximately 1.5 hours and reduced Cmax by 26%. No clinically relevant effects on AUC were observed. The mechanism of this potential interaction has not been described (although it may be due to delayed gastric emptying) and the potential for clinical significance is unknown. Dosage adjustments of digoxin may be necessary.

For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Dorzolamide; Timolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Edetate Calcium Disodium, Calcium EDTA: (Minor) Use caution in administration of calcium EDTA to patients with diabetes mellitus who are receiving insulin therapy. Calcium EDTA chelates the zinc in selected exogenous insulins, thereby increasing the amount of insulin available to the body and decreasing the duration of the insulin dose. Alterations in blood glucose control may result. Diabetic patients receiving calcium EDTA may require adjustments in their insulin dosage.
Elagolix; Estradiol; Norethindrone acetate: (Moderate) Separate the administration times of lixisenatide and estrogen and progestin containing oral contraceptives.

Furosemide: (Minor) Monitor patients receiving insulin closely for worsening glycemic control when bumetanide, furosemide, and torsemide are instituted. Bumetanide, furosemide, and torsemide may cause hyperglycemia and glycosuria in patients with diabetes mellitus, probably due to diuretic-induced hypokalemia. Because of this, a potential pharmacodynamic interaction exists between these drugs and all antidiabetic agents.
Garlic, Allium sativum: (Moderate) Patients receiving antidiabetic agents should use dietary supplements of Garlic, Allium sativum with caution. Constituents in garlic might have some antidiabetic activity, and may increase serum insulin levels and increase glycogen storage in the liver. Monitor blood glucose and glycemic control. Patients with diabetes should inform their health care professionals of their intent to ingest garlic dietary supplements. Some patients may require adjustment to their hypoglycemic medications over time. One study stated that additional garlic supplementation (0.05 to 1.5 grams PO per day) contributed to improved blood glucose control in patients with type 2 diabetes mellitus within 1 to 2 weeks, and had positive effects on total cholesterol and high/low density lipoprotein regulation over time. It is unclear if hemoglobin A1C is improved or if improvements are sustained with continued treatment beyond 24 weeks. Other reviews suggest that garlic may provide modest improvements in blood lipids, but few studies demonstrate decreases in blood glucose in diabetic and non-diabetic patients. More controlled trials are needed to discern if garlic has an effect on blood glucose in patients with diabetes. When garlic is used in foods or as a seasoning, or at doses of 50 mg/day or less, it is unlikely that blood glucose levels are affected to any clinically significant degree.

For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Labetalol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.

Patients should be advised to eat within 20 minutes of mecasermin administration. Glucose monitoring is important when initializing or adjusting mecasermin therapies, when adjusting concomitant antidiabetic therapy, and in the event of hypoglycemic symptoms. An increased risk for hypoglycemia is possible. The hypoglycemic effect induced by IGF-1 activity may be exacerbated. The amino acid sequence of mecasermin (rh-IGF-1) is approximately 50 percent homologous to insulin and cross binding with either receptor is possible. Treatment with mecasermin has been shown to improve insulin sensitivity and to improve glycemic control in patients with either Type 1 or Type 2 diabetes mellitus when used alone or in conjunction with insulins.

(Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as repaglinide. Although specific dose recommendations are not available, a lower dose of repaglinide may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Metformin; Rosiglitazone: (Major) Use of insulins with rosiglitazone is not recommended by the manufacturer due to a potential increased risk for edema or heart failure. If heart failure develops in a patient receiving insulin and a thiazoladinedione, manage the patient according to standards of care, and discontinue or consider reducing the dose of the thiazoladinedione. Since the incidence of hypoglycemia may also be higher with combined therapy, patients should also be instructed to monitor blood glucose concentrations more frequently. In five 26-week trials involving patients with type 2 diabetes, rosiglitazone added to insulin therapy (n=867) was compared with insulin therapy alone (n=663). These trials included patients with chronic diabetes and a high prevalence of coexisting medical conditions, including peripheral neuropathy, retinopathy, ischemic heart disease, vascular disease, and congestive heart failure. In these clinical studies, an increased incidence of heart failure and other cardiovascular adverse events was seen in patients receiving combination rosiglitazone and insulin therapy compared to insulin monotherapy; the incidence of new onset or exacerbated heart failure was 0.9% in patients treated with insulin alone vs. 2% in patients treated with insulin plus rosiglitazone. Some of the patients who developed cardiac failure on combination therapy during the double blind part of the studies had no known prior evidence of congestive heart failure, or pre-existing cardiac condition. Additionally, the results of a meta-analysis that included the same 5 randomized, controlled trials mentioned previously indicate that the rate of myocardial ischemia may be increased in patients taking rosiglitazone in combination with insulin; the incidence of myocardia ischemia was 1.4% in patients receiving insulin monotherapy vs. 2.8% in patients receiving rosiglitazone and insulin combination therapy (OR 2.1 95% CI 0.9-5.1). The cardiovascular events were noted at doses of both 4 mg/day and 8 mg/day of rosiglitazone. In a sixth 26-week study, patients with baseline congestive heart failure were excluded; in this study, compared to insulin monotherapy (n=158), the addition of rosiglitazone to insulin therapy (n=161) did not increase the risk of congestive heart failure. One each of myocardial ischemia and sudden death were reported in patients taking combination therapy compared to zero patients taking insulin monotherapy. When rosiglitazone was added to insulin therapy, the incidence of hypoglycemia was higher with 8 mg/day of rosiglitazone (67%) compared to 4 mg/day (53%). (Moderate) Monitor blood glucose during concomitant metformin and insulin use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Metformin; Saxagliptin: (Moderate) A lower insulin dose may be required when used in combination with saxagliptin to minimize the risk of hypoglycemia. When saxagliptin was used in combination with insulin, the incidence of hypoglycemia was increased compared to a placebo used in combination with insulin. (Moderate) Monitor blood glucose during concomitant metformin and insulin use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Metformin; Sitagliptin: (Moderate) Monitor blood glucose during concomitant metformin and insulin use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Methamphetamine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Methazolamide: (Minor) Carbonic anhydrase inhibitors may alter blood sugar. Both hyperglycemia and hypoglycemia have been described in patients treated with acetazolamide. This should be taken into consideration in patients with impaired glucose tolerance or diabetes mellitus who are receiving antidiabetic agents. Monitor blood glucose and for changes in glycemic control and be alert for evidence of an interaction.
Methenamine; Sodium Salicylate: (Moderate) Monitor blood glucose during concomitant incretin mimetic and salicylate use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and salicylate use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Methohexital: (Minor) The risk of developing hypothermia is increased when methohexital is used with hypothermia-producing agents such as ethanol, insulins, phenothiazines, or other general anesthetics.
Methyclothiazide: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Methylphenidate: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Methylprednisolone: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Methyltestosterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Metoclopramide: (Moderate) Increased GI motility by metoclopramide may increase delivery of food to the intestines and increase blood glucose. The dosing of insulin may require adjustment in patients who receive metoclopramide concomitantly.
Metolazone: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Metoprolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Metoprolol; Hydrochlorothiazide, HCTZ: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Metreleptin: (Moderate) Use caution when administering metreleptin to patients treated with concomitant insulins or insulin secretagogue therapy (i.e., sulfonylureas, nateglinide, repaglinide). In clinical evaluation of metreleptin, hypoglycemia occurred in 13% of patients with generalized lipodystrophy. Most reported cases occurred with concomitant insulin use, with or without oral antihyperglycemic agents. Closely monitor blood glucose in patients on concomitant insulin or insulin secretagogue therapy. Dosage adjustments to their antihyperglycemic medications may be necessary.
Metyrapone: (Moderate) In patients taking insulin or other antidiabetic agents, the signs and symptoms of acute metyrapone toxicity (e.g., symptoms of acute adrenal insufficiency) may be aggravated or modified.
Midodrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Moexipril: (Moderate) Monitor blood glucose during concomitant incretin mimetic and angiotensin-converting enzyme (ACE) inhibitor use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin-converting enzyme (ACE) inhibitor use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Mometasone: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance.

Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Nadolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Naproxen; Pseudoephedrine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Nateglinide: (Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as nateglinide. Although specific dose recommendations are not available, a lower dose of nateglinide may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Nebivolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Nebivolol; Valsartan: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Nelfinavir: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control, specifically hyperglycemia, when anti-retroviral protease inhibitors are instituted. New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. Another possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of protease inhibitors. Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.
Niacin, Niacinamide: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when niacin, niacinamide is instituted or discontinued. Dosage adjustments may be necessary. Niacin interferes with glucose metabolism and can result in hyperglycemia. When used at daily doses of 750 to 2000 mg, niacin significantly lowers LDL cholesterol and triglycerides while increasing HDL cholesterol. Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy. (Moderate) Niacin (nicotinic acid) interferes with glucose metabolism and can result in hyperglycemia. Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy. Monitor patients taking antidiabetic agents for changes in glycemic control if niacin (nicotinic acid) is added or deleted to the medication regimen. Dosage adjustments may be necessary.
Niacin; Simvastatin: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when niacin, niacinamide is instituted or discontinued. Dosage adjustments may be necessary. Niacin interferes with glucose metabolism and can result in hyperglycemia. When used at daily doses of 750 to 2000 mg, niacin significantly lowers LDL cholesterol and triglycerides while increasing HDL cholesterol. Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy.

Changes in glycemic control can usually be corrected through modification of hypoglycemic therapy. Monitor patients taking antidiabetic agents for changes in glycemic control if niacin (nicotinic acid) is added or deleted to the medication regimen. Dosage adjustments may be necessary.
Nicotine: (Minor) Monitor blood glucose concentrations for needed antidiabetic agent dosage adjustments in diabetic patients whenever a change in either nicotine intake or smoking status occurs. Nicotine activates neuroendocrine pathways (e.g., increases in circulating cortisol and catecholamine levels) and may increase plasma glucose. Tobacco smoking is known to aggravate insulin resistance. Cessation of nicotine therapy or tobacco smoking may result in a decrease in blood glucose. (Minor) Nicotine may increase plasma glucose. Monitor blood sugar for needed insulin dosage adjustments in insulin-dependent diabetic patients whenever a change in either nicotine intake or smoking status occurs. In addition, the use of inhaled insulin is not recommended in patients who smoke. Smoking tobacco can alter the effect of inhaled insulin in several ways. First, nicotine activates neuroendocrine pathways (e.g., increases in circulating cortisol and catecholamine levels) and may increase plasma glucose. Second, tobacco smoking is known to aggravate insulin resistance. Finally, compared with non-smokers, insulin exposure after inhalation may be greater in patients who smoke. If inhaled insulin is used in this population, patients should be instructed to monitor blood glucose concentrations closely. If a change in smoking status or nicotine intake occur, patients should continue to monitor their blood glucose concentrations closely and clinicians should adjust the dose of insulin when indicated.
Nirmatrelvir; Ritonavir: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control, specifically hyperglycemia, when anti-retroviral protease inhibitors are instituted. New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors.

Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Norethindrone Acetate; Ethinyl Estradiol; Ferrous fumarate: (Moderate) Separate the administration times of lixisenatide and estrogen and progestin containing oral contraceptives. Advise patients to take estrogen and progestin containing oral contraceptives at least 1 hour before or 11 hours after lixisenatide. Lixisenatide slows gastric emptying and simultaneous coadministration may reduce the rate and extent of estrogen and progestin oral absorption which may reduce efficacy. Additionally, estrogens can impair glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day. (Minor) Patients receiving antidiabetic agents should be periodically monitored for changes in glycemic control when hormone therapy is instituted or discontinued. Estrogens can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day in combined oral contraceptives (COCs), which are not commonly used in practice since the marketing of lower dose COCs, patches, injections and rings.

(Minor) Progestins can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Patients receiving antidiabetic agents should be closely monitored for changes in diabetic control when hormone therapy is instituted or discontinued.
Octreotide: (Moderate) Monitor patients receiving octreotide concomitantly with insulin or other antidiabetic agents for changes in glycemic control and adjust doses of these medications accordingly. Octreotide alters the balance between the counter-regulatory hormones of insulin, glucagon, and growth hormone, which may result in hypoglycemia or hyperglycemia. The hypoglycemia or hyperglycemia which occurs during octreotide acetate therapy is usually mild but may result in overt diabetes mellitus or necessitate dose changes in insulin or other hypoglycemic agents. In patients with concomitant type1 diabetes mellitus, octreotide is likely to affect glucose regulation, and insulin requirements may be reduced. Symptomatic hypoglycemia, which may be severe, has been reported in type 1 diabetic patients. In Type 2 diabetes patients with partially intact insulin reserves, octreotide administration may result in decreases in plasma insulin levels and hyperglycemia.
Olanzapine: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and insulin use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.
Olanzapine; Fluoxetine: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and insulin use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition. (Moderate) Monitor blood glucose during concomitant incretin mimetic and fluoxetine use; an incretin mimetic dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Olmesartan; Hydrochlorothiazide, HCTZ: (Moderate) Monitor blood glucose during concomitant incretin mimetic and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Olopatadine; Mometasone: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Oral Contraceptives: (Moderate) Separate the administration times of lixisenatide and estrogen and progestin containing oral contraceptives. Advise patients to take estrogen and progestin containing oral contraceptives at least 1 hour before or 11 hours after lixisenatide. Lixisenatide slows gastric emptying and simultaneous coadministration may reduce the rate and extent of estrogen and progestin oral absorption which may reduce efficacy. Additionally, estrogens can impair glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day.
Orlistat: (Minor) Weight-loss may affect glycemic control in patients with diabetes mellitus. In many patients, glycemic control may improve. A reduction in dose of insulins or other medicines for diabetes may be required in some patients taking orlistat. Monitor blood glucose and glycemic control and adjust therapy as clinically indicated. (Minor) Weight-loss may affect glycemic control in patients with diabetes mellitus. In many patients, glycemic control may improve. A reduction in dose of oral hypoglycemic medications may be required in some patients taking orlistat. Monitor blood glucose and glycemic control and adjust therapy as clinically indicated.
Oxandrolone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens.

Monitor blood glucose and HbA1C when these drugs are used together.
Oxymetholone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Paliperidone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and insulin use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.
Pasireotide: (Moderate) Monitor blood glucose levels regularly in patients with diabetes, especially when pasireotide treatment is initiated or when the dose is altered.

Patients treated with pasireotide may experience either hypoglycemia or hyperglycemia.
Pegvisomant: (Moderate) Monitor blood glucose levels regularly in patients with diabetes, especially when pegvisomant treatment is initiated or when the dose is altered. Adjust treatment with antidiabetic agents as clinically indicated. Pegvisomant increases sensitivity to insulin by lowering the activity of growth hormone, and in some patients glucose tolerance improves with treatment. Patients with diabetes treated with pegvisomant and antidiabetic agents may be more likely to experience hypoglycemia.
Pentamidine: (Moderate) Monitor patients receiving insulin closely for changes in glycemic control during the use of pentamidine; dosage adjustments of insulin may be necessary. Pentamidine can be harmful to pancreatic cells. This effect may lead to hypoglycemia acutely, followed hyperglycemia with prolonged pentamidine therapy. (Moderate) Pentamidine can be harmful to pancreatic cells. This effect may lead to hypoglycemia acutely, followed by hyperglycemia with prolonged pentamidine therapy. Patients on antidiabetic agents should be monitored for the need for dosage adjustments during the use of pentamidine.

Phendimetrazine: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Phenelzine: (Moderate) Monitor blood glucose during concomitant incretin mimetic and monoamine oxidase inhibitor (MAOI) use; an incretin mimetic dose adjustment may be necessary.

Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Phenytoin: (Minor) Phenytoin and other hydantoins have the potential to increase blood glucose and thus interact with antidiabetic agents pharmacodynamically. Monitor blood glucose for changes in glycemic control. Dosage adjustments may be necessary in some patients. (Minor) Phenytoin can decrease the hypoglycemic effects of lixisenatide by producing an increase in blood glucose levels. Monitor for signs indicating loss of diabetic control when therapy with a hydantoin is instituted. Conversely, patients should be closely monitored for signs of hypoglycemia when therapy with a hydantoin is discontinued.
Pindolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Pioglitazone: (Moderate) Monitor blood glucose and for signs and symptoms of heart failure during concomitant pioglitazone and insulin use. Reduce the insulin dose by 10% to 25% if hypoglycemia occurs; adjust the insulin dose further based on glycemic response. Consider discontinuation of pioglitazone if heart failure occurs and manage according to current standards. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia and fluid retention which may lead to or exacerbate heart failure.
Pioglitazone; Glimepiride: (Moderate) Monitor blood glucose and for signs and symptoms of heart failure during concomitant pioglitazone and insulin use. Reduce the insulin dose by 10% to 25% if hypoglycemia occurs; adjust the insulin dose further based on glycemic response.

(Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as the sulfonylureas. Although specific dose recommendations are not available, a lower dose of the sulfonylurea may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Pioglitazone; Metformin: (Moderate) Monitor blood glucose and for signs and symptoms of heart failure during concomitant pioglitazone and insulin use. Reduce the insulin dose by 10% to 25% if hypoglycemia occurs; adjust the insulin dose further based on glycemic response.

(Moderate) Monitor blood glucose during concomitant metformin and insulin use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Pramlintide: (Major) Reduce mealtime insulin doses, including premixed insulins, by 50% when starting pramlintide to reduce the risk of hypoglycemia; further reductions in insulin dose are dependent on individual patient response.

Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of protease inhibitors.

Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.
Rosiglitazone: (Major) Use of insulins with rosiglitazone is not recommended by the manufacturer due to a potential increased risk for edema or heart failure. If heart failure develops in a patient receiving insulin and a thiazoladinedione, manage the patient according to standards of care, and discontinue or consider reducing the dose of the thiazoladinedione. Since the incidence of hypoglycemia may also be higher with combined therapy, patients should also be instructed to monitor blood glucose concentrations more frequently. In five 26-week trials involving patients with type 2 diabetes, rosiglitazone added to insulin therapy (n=867) was compared with insulin therapy alone (n=663). These trials included patients with chronic diabetes and a high prevalence of coexisting medical conditions, including peripheral neuropathy, retinopathy, ischemic heart disease, vascular disease, and congestive heart failure. In these clinical studies, an increased incidence of heart failure and other cardiovascular adverse events was seen in patients receiving combination rosiglitazone and insulin therapy compared to insulin monotherapy; the incidence of new onset or exacerbated heart failure was 0.9% in patients treated with insulin alone vs. 2% in patients treated with insulin plus rosiglitazone. Some of the patients who developed cardiac failure on combination therapy during the double blind part of the studies had no known prior evidence of congestive heart failure, or pre-existing cardiac condition. Additionally, the results of a meta-analysis that included the same 5 randomized, controlled trials mentioned previously indicate that the rate of myocardial ischemia may be increased in patients taking rosiglitazone in combination with insulin; the incidence of myocardia ischemia was 1.4% in patients receiving insulin monotherapy vs. 2.8% in patients receiving rosiglitazone and insulin combination therapy (OR 2.1 95% CI 0.9-5.1). The cardiovascular events were noted at doses of both 4 mg/day and 8 mg/day of rosiglitazone. In a sixth 26-week study, patients with baseline congestive heart failure were excluded; in this study, compared to insulin monotherapy (n=158), the addition of rosiglitazone to insulin therapy (n=161) did not increase the risk of congestive heart failure. One each of myocardial ischemia and sudden death were reported in patients taking combination therapy compared to zero patients taking insulin monotherapy. When rosiglitazone was added to insulin therapy, the incidence of hypoglycemia was higher with 8 mg/day of rosiglitazone (67%) compared to 4 mg/day (53%).

Saxagliptin: (Moderate) A lower insulin dose may be required when used in combination with saxagliptin to minimize the risk of hypoglycemia. When saxagliptin was used in combination with insulin, the incidence of hypoglycemia was increased compared to a placebo used in combination with insulin.
Segesterone Acetate; Ethinyl Estradiol: (Moderate) Separate the administration times of lixisenatide and estrogen and progestin containing oral contraceptives. Advise patients to take estrogen and progestin containing oral contraceptives at least 1 hour before or 11 hours after lixisenatide. Lixisenatide slows gastric emptying and simultaneous coadministration may reduce the rate and extent of estrogen and progestin oral absorption which may reduce efficacy. Additionally, estrogens can impair glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day. (Minor) Patients receiving antidiabetic agents should be periodically monitored for changes in glycemic control when hormone therapy is instituted or discontinued. Estrogens can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Changes in glucose tolerance occur more commonly in patients receiving 50 mcg or more of ethinyl estradiol (or equivalent) per day in combined oral contraceptives (COCs), which are not commonly used in practice since the marketing of lower dose COCs, patches, injections and rings. The presence or absence of a concomitant progestin may influence the significance of any hormonal effect on glucose homeostasis. (Minor) Progestins can decrease the hypoglycemic effects of antidiabetic agents by impairing glucose tolerance. Patients receiving antidiabetic agents should be closely monitored for changes in diabetic control when hormone therapy is instituted or discontinued.
Semaglutide: (Moderate) Monitor blood glucose during concomitant insulin glargine and semaglutide use; consider decreasing the insulin glargine dose when starting semaglutide. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Serdexmethylphenidate; Dexmethylphenidate: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking insulin. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Sodium Polystyrene Sulfonate: (Moderate) Sodium polystyrene sulfonate should be used cautiously with other agents that can induce hypokalemia such as loop diuretics, insulins, or intravenous sodium bicarbonate. Because of differences in onset of action, sodium polystyrene sulfonate is often used with these agents. With appropriate monitoring, hypokalemia can be avoided.
Sofosbuvir: (Moderate) Closely monitor blood glucose levels if sofosbuvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as sofosbuvir.
Sofosbuvir; Velpatasvir: (Moderate) Closely monitor blood glucose levels if sofosbuvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as sofosbuvir. (Moderate) Closely monitor blood glucose levels if velpatasvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as velpatasvir.
Sofosbuvir; Velpatasvir; Voxilaprevir: (Moderate) Closely monitor blood glucose levels if sofosbuvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as sofosbuvir. (Moderate) Closely monitor blood glucose levels if velpatasvir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as velpatasvir. (Moderate) Closely monitor blood glucose levels if voxilaprevir is administered with antidiabetic agents. Dose adjustments of the antidiabetic agents may be needed. Altered blood glucose control, resulting in serious symptomatic hypoglycemia, has been reported in diabetic patients receiving antidiabetic agents in combination with direct acting antivirals, such as voxilaprevir.
Somapacitan: (Moderate) Patients with diabetes mellitus should be monitored closely during somapacitan therapy. Antidiabetic drugs (e.g., insulin or oral agents) may require adjustment when somapacitan therapy is instituted in these patients. Growth hormones, such as somapacitan, may decrease insulin sensitivity, leading to glucose intolerance and loss of blood glucose control. Therefore, glucose levels should be monitored periodically in all patients treated with somapacitan, especially in those with risk factors for diabetes mellitus.
Somatrogon: (Moderate) Monitor for loss of glycemic control if concomitant use of somatrogon and antidiabetic drugs is necessary; a dose adjustment of the antidiabetic drug may be needed. Growth hormones, such as somatrogon, may decrease insulin sensitivity, leading to glucose intolerance and loss of blood glucose control.
Somatropin, rh-GH: (Moderate) Patients with diabetes mellitus should be monitored closely during somatropin (recombinant rhGH) therapy. Antidiabetic drugs (e.g., insulin or oral agents) may require adjustment when somatropin therapy is instituted in these patients. Growth hormones, such as somatropin, may decrease insulin sensitivity, leading to glucose intolerance and loss of blood glucose control. Therefore, glucose levels should be monitored periodically in all patients treated with somatropin, especially in those with risk factors for diabetes mellitus.
Sotalol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose. Some beta-blockers, particularly non-selective beta-blockers such as propranolol, have been noted to potentiate insulin-induced hypoglycemia and a delay in recovery of blood glucose to normal levels. Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Spironolactone; Hydrochlorothiazide, HCTZ: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Sulfadiazine: (Moderate) Monitor blood glucose during concomitant insulin and sulfonamide use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Sulfamethoxazole; Trimethoprim, SMX-TMP, Cotrimoxazole: (Moderate) Monitor blood glucose during concomitant insulin and sulfonamide use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

(Moderate) Monitor blood glucose during concomitant insulin and sulfonamide use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Sulfonylureas: (Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as the sulfonylureas. Although specific dose recommendations are not available, a lower dose of the sulfonylurea may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Sympathomimetics: (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically. Monitor for loss of glycemic control when sympathomimetics are administered to patients taking incretin mimetics. Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes. (Moderate) Sympathomimetic agents tend to increase blood glucose concentrations when administered systemically.

Sympathomimetics, through stimulation of alpha- and beta- receptors, increase hepatic glucose production and glycogenolysis and inhibit insulin secretion. Also, adrenergic medications may decrease glucose uptake by muscle cells. For treatment of cold symptoms, nasal decongestants may be preferable for short term, limited use (1 to 3 days) as an alternative to systemic decongestants in patients taking medications for diabetes.
Tacrolimus: (Moderate) Patients should be monitored for worsening of glycemic control if therapy with tacrolimus is initiated in patients receiving antidiabetic agents, including lixisenatide. Tacrolimus has been reported to cause hyperglycemia. Furthermore, tacrolimus has been implicated in causing insu lin-dependent diabetes mellitus in patients after renal transplantation. The mechanism of hyperglycemia is thought to be through direct beta-cell toxicity. (Moderate) Tacrolimus has been reported to cause hyperglycemia. Patients should be monitored for worsening of glycemic control if therapy with tacrolimus is initiated in patients receiving antidiabetic agents.
Tegaserod: (Moderate) Because tegaserod can enhance gastric emptying in patients with diabetes, blood glucose can be affected, which, in turn, may affect the clinical response to antidiabetic agents. (Moderate) Tegaserod can enhance gastric emptying in patients with diabetes. Typically, blood glucose could be affected, which, in turn, may affect the clinical response to antidiabetic agents. However, incretin mimetics have been shown to slow gastric emptying. The clinical effects of these competing mechanisms is not known. The dosing of antidiabetic agents may require adjustment and blood glucose should be closely monitored when coadministered with tegaserod.
Telmisartan: (Moderate) Monitor blood glucose during concomitant incretin mimetic and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Testosterone: (Moderate) Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, may decrease antidiabetic agent dosage requirements. Monitor blood glucose and HbA1C when these drugs are used together.
Thiazide diuretics: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes. (Moderate) Thiazide diuretics can decrease insulin sensitivity thereby leading to glucose intolerance and hyperglycemia. Diuretic-induced hypokalemia may also lead to hyperglycemia. Because of this, a potential pharmacodynamic interaction exists between thiazide diuretics and antidiabetic agents. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes. However, patients taking antidiabetic agents should be monitored for changes in blood glucose control if such diuretics are added or deleted. Dosage adjustments may be necessary. Finally, both thiazides and sulfonylureas have been reported to cause photosensitivity reactions; concomitant use may increase the risk of photosensitivity.
Thioridazine: (Minor) Phenothiazines, especially chlorpromazine, may increase blood glucose concentrations. Hyperglycemia and glycosuria have been reported. Patients who are taking antidiabetic agents should monitor for worsening glycemic control when a phenothiazine is instituted.
Thyroid hormones: (Minor) Monitor patients receiving insulin closely for changes in diabetic control whenever there is a change in thyroid treatment. It may be necessary to adjust the dose of antidiabetic agents if thyroid hormones are added or discontinued. Thyroid hormones are important in the regulation of carbohydrate metabolism, gluconeogenesis, the mobilization of glycogen stores, and protein synthesis. When thyroid hormones are added to existing diabetes therapy, the glucose-lowering effect may be reduced. (Minor) When thyroid hormones are added to existing diabetes therapy, the glucose-lowering effect may be reduced. Close monitoring of blood glucose is necessary for individuals who use antidiabetic agents whenever there is a change in thyroid treatment. It may be necessary to adjust the dose of antidiabetic agents if thyroid hormones are added or discontinued. Thyroid hormones are important in the regulation of carbohydrate metabolism, gluconeogenesis, the mobilization of glycogen stores, and protein synthesis.
Timolol: (Moderate) Increased frequency of blood glucose monitoring may be required when a beta blocker is given with antidiabetic agents. Since beta blockers inhibit the release of catecholamines, these medications may hide symptoms of hypoglycemia such as tremor, tachycardia, and blood pressure changes. Other symptoms, like headache, dizziness, nervousness, mood changes, or hunger are not blunted. Beta-blockers also exert complex actions on the body's ability to regulate blood glucose.

Hyperglycemia has been reported as well and is possibly due to beta-2 receptor blockade in the beta cells of the pancreas. A selective beta-blocker may be preferred in patients with diabetes mellitus, if appropriate for the patient's condition. Selective beta-blockers, such as atenolol or metoprolol, do not appear to potentiate insulin-induced hypoglycemia. While beta-blockers may have negative effects on glycemic control, they reduce the risk of cardiovascular disease and stroke in patients with diabetes and their use should not be avoided in patients with compelling indications for beta-blocker therapy when no other contraindications are present.
Tipranavir: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control, specifically hyperglycemia, when anti-retroviral protease inhibitors are instituted. New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of anti-retroviral protease inhibitors. Another possible mechanism is impairment of beta-cell function. Onset averaged approximately 63 days after initiating protease inhibitor therapy, but has occurred as early as 4 days after beginning therapy. Diabetic ketoacidosis has occurred in some patients including patients who were not diabetic prior to protease inhibitor treatment. (Moderate) New onset diabetes mellitus, exacerbation of diabetes mellitus, and hyperglycemia due to insulin resistance have been reported with use of protease inhibitors. Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.
Tirzepatide: (Moderate) When tirzepatide is used with insulin, consider lowering the dose of the insulin to reduce the risk of hypoglycemia and monitor the blood glucose concentration more frequently. Patients receiving tirzepatide in combination with insulin may have an increased risk of hypoglycemia, including severe hypoglycemia.
Tobacco: (Major) Advise patients to avoid smoking tobacco while taking insulin. Tobacco smoking is known to aggravate insulin resistance. The cessation of nicotine therapy or tobacco smoking may result in a decrease in blood glucose. Blood glucose concentrations should be monitored more closely whenever a change in either nicotine intake or smoking status occurs; dosage adjustments in antidiabetic agents may be needed.
Tolazamide: (Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as the sulfonylureas. Although specific dose recommendations are not available, a lower dose of the sulfonylurea may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Tolbutamide: (Moderate) The risk of hypoglycemia is increased when lixisenatide is used in combination with insulin secretagogues such as the sulfonylureas. Although specific dose recommendations are not available, a lower dose of the sulfonylurea may be required to reduce the risk of hypoglycemia in this setting. Adequate blood glucose monitoring should be continued and followed.
Torsemide: (Minor) Monitor patients receiving insulin closely for worsening glycemic control when bumetanide, furosemide, and torsemide are instituted. Bumetanide, furosemide, and torsemide may cause hyperglycemia and glycosuria in patients with diabetes mellitus, probably due to diuretic-induced hypokalemia. Because of this, a potential pharmacodynamic interaction exists between these drugs and all antidiabetic agents.
Tramadol; Acetaminophen: (Minor) When 1,000 mg acetaminophen was given 1 or 4 hours after 10 mcg lixisenatide, the AUC was not significantly changed, but the acetaminophen Cmax was decreased by 29% and 31%, respectively and median Tmax was delayed by 2 and 1.75 hours, respectively. Acetaminophen AUC, Cmax, and Tmax were not significantly changed when acetaminophen was given 1 h before lixisenatide injection. The mechanism of this interaction is not available (although it may be due to delayed gastric emptying) and the clinical impact has not been assessed. To avoid potential pharmacokinetic interactions that might alter effectiveness of acetaminophen, it may be advisable for patients to take acetaminophen at least one hour prior to lixisenatide subcutaneous injection.
Trandolapril: (Moderate) Monitor blood glucose during concomitant incretin mimetic and angiotensin-converting enzyme (ACE) inhibitor use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin-converting enzyme (ACE) inhibitor use; an insulin dose adjustment may be necessary.

(Moderate) Monitor blood glucose during concomitant insulin and monoamine oxidase inhibitor (MAOI) use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Triamcinolone: (Moderate) Monitor blood glucose during concomitant corticosteroid and insulin use; an insulin dose adjustment may be necessary. Corticosteroids may increase blood glucose concentrations. Risk factors for impaired glucose tolerance due to corticosteroids include the corticosteroid dose and duration of treatment. Corticosteroids stimulate hepatic glucose production and inhibit peripheral glucose uptake into muscle and fatty tissues, producing insulin resistance. Decreased insulin production may occur in the pancreas due to a direct effect on pancreatic beta cells.
Triamterene: (Minor) Triamterene can decrease the hypoglycemic effects of antidiabetic agents, such as incretin mimetics, by producing an increase in blood glucose levels. Patients on antidiabetics should be monitored for changes in blood glucose control if triamterene is added or deleted. Dosage adjustments may be necessary. (Minor) Triamterene can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. Patients receiving insulin should be closely monitored for signs indicating loss of diabetic control when therapy with triamterene is instituted. In addition, patients receiving insulin should be closely monitored for signs of hypoglycemia when therapy with any of these other agents is discontinued.
Triamterene; Hydrochlorothiazide, HCTZ: (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes. (Minor) Triamterene can decrease the hypoglycemic effects of antidiabetic agents, such as incretin mimetics, by producing an increase in blood glucose levels. Patients on antidiabetics should be monitored for changes in blood glucose control if triamterene is added or deleted. Dosage adjustments may be necessary. (Minor) Triamterene can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. Patients receiving insulin should be closely monitored for signs indicating loss of diabetic control when therapy with triamterene is instituted. In addition, patients receiving insulin should be closely monitored for signs of hypoglycemia when therapy with any of these other agents is discontinued.
Trifluoperazine: (Minor) Phenothiazines, especially chlorpromazine, may increase blood glucose concentrations. Hyperglycemia and glycosuria have been reported. Patients who are taking antidiabetic agents should monitor for worsening glycemic control when a phenothiazine is instituted.
Valsartan: (Moderate) Monitor blood glucose during concomitant incretin mimetic and angiotensin receptor blocker use. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.

Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor blood glucose during concomitant insulin and angiotensin II receptor blocker use; an insulin dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia. (Moderate) Monitor patients receiving insulin closely for changes in diabetic control when thiazide diuretics are instituted or discontinued; dosage adjustments may be required. Thiazide diuretics can decrease the hypoglycemic effects of insulin by producing an increase in blood glucose levels. It appears that the effects of thiazide diuretics on glycemic control are dose-related and low doses can be instituted without deleterious effects on glycemic control. In addition, diuretics reduce the risk of stroke and cardiovascular disease in patients with diabetes.
Vonoprazan; Amoxicillin; Clarithromycin: (Moderate) The concomitant use of clarithromycin and antidiabetic agents can result in significant hypoglycemia. Careful monitoring of blood glucose is recommended. (Moderate) The concomitant use of clarithromycin and insulin or other antidiabetic agents can result in significant hypoglycemia. Careful monitoring of blood glucose is recommended.
Warfarin: (Moderate) Concomitant administration of 25 mg of warfarin with repeated dosing of lixisenatide 20 mcg delayed warfarin Tmax by approximately 7 hours and reduced Cmax by 19%. No clinically relevant effects on AUC or INR were observed. Although increased INR has not been reported in patients receiving warfarin and lixisenatide, cases of an increased INR have been reported with the concomitant use of warfarin and exenatide. Clinicians should closely monitor patients for changes in INR and bleeding when these drugs are coadministered. Dosage adjustments of warfarin may be necessary.
Ziprasidone: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and insulin use. Atypical antipsychotic therapy may aggravate diabetes mellitus. Atypical antipsychotics have been associated with metabolic changes, including hyperglycemia, diabetic ketoacidosis, hyperosmolar, hyperglycemic states, and diabetic coma. Possible mechanisms include atypical antipsychotic-induced insulin resistance or direct beta-cell inhibition.

Combination products containing insulin glargine and lixisenatide are used to improve glycemic control in type 2 diabetes mellitus. Clinicians may wish to consult the individual monographs for more information about each agent.
Insulin glargine: Endogenous insulin regulates carbohydrate, fat, and protein metabolism by several mechanisms; in general, insulin promotes the storage and inhibits the breakdown of glucose, fat, and amino acids. Insulin lowers glucose concentrations by facilitating the uptake of glucose in muscle and adipose tissue and by inhibiting hepatic glucose production (glycogenolysis and gluconeogenesis). Insulin also regulates fat metabolism by enhancing the storage of fat (lipogenesis) and inhibiting the mobilization of fat for energy in adipose tissues (lipolysis and free fatty acid oxidation). Finally, insulin is involved in the regulation of protein metabolism by increasing protein synthesis and inhibiting proteolysis in muscle tissue.
Lixisenatide: Lixisenatide is an incretin mimetic; specifically, lixisenatide is a glucagon-like peptide-1 (GLP-1) receptor agonist. Lixisenatide binds and activates the GLP-1 receptor. GLP-1 is an important, gut-derived, glucose homeostasis regulator that is released after the oral ingestion of carbohydrates or fats. In patients with type 2 diabetes, GLP-1 concentrations are decreased in response to an oral glucose load. GLP-1 enhances insulin secretion; it increases glucose-dependent insulin synthesis and in vivo secretion of insulin from pancreatic beta cells in the presence of elevated glucose. In addition to increases in insulin secretion and synthesis, GLP-1 suppresses glucagon secretion, slows gastric emptying, reduces food intake, and promotes beta-cell proliferation. At a dose 1.5 times the recommended dose, lixisenatide does not prolong the QTc interval to any clinical relevant extent.

Insulin glargine; lixisenatide is administered subcutaneously. Overall the pharmacokinetics of insulin glargine and lixenatide were not affected in a clinically relevant manner when administered as the combination, Soliqua injection.
Insulin glargine: Endogenous insulin distributes widely throughout the body. A small portion is inactivated by peripheral tissues, but the majority is metabolized by the liver and kidneys. After subcutaneous injection of insulin glargine in diabetic patients, insulin glargine is metabolized at the carboxyl terminus of the Beta chain with formation of two active metabolites M1 (21A-Gly-insulin) and M2 (21A-Gly-des-30B-Thr-insulin). The in vitro activity of M1 and M2 were similar to that of insulin. Insulin is filtered and reabsorbed by the kidneys; the plasma half-life of human endogenous insulin is approximately 5 to 6 minutes.
Lixenatide: The protein binding of lixisenatide is 55%. The mean apparent volume of distribution following subcutaneous administration of lixisenatide is approximately 100 L. Lixisenatide is presumed to be eliminated through glomerular filtration and proteolytic degradation. After multiple dose administration in patients with type 2 diabetes, the mean terminal half-life was approximately 3 hours and the mean apparent clearance was about 35 L/hour. In adults with type 2 diabetes mellitus, lixisenatide reduces fasting plasma glucose concentration and postprandial blood glucose AUC compared to placebo (-33.8 mg/dL and -387 mg x hour/dL, respectively) following a standardized test meal. The effect on postprandial blood glucose AUC is most notable with the first meal and attenuates with later meals in the day.
 
Affected cytochrome P450 (CYP450) isoenzymes and drug transporters: None

Subcutaneous Route

Following subcutaneous injection of insulin glargine; lixisenatide combinations, insulin glargine showed no pronounced peak. Exposure to insulin glargine ranged from 86% to 101% compared to administration of insulin glargine alone. The median Tmax of insulin glargine; lixisenatide was 2.5 to 3 hours. There was a small decrease in lixisenatide Cmax of 22% to 24% compared with separate simultaneous administration, which is not likely to be clinically significant. Similar absorption is achieved with subcutaneous administration of lixisenatide in the abdomen, thigh, or arm.

Pregnancy

Data for insulin glargine; lixisenatide are not sufficient to inform if there is a drug-associated risk of major birth defects and miscarriage when used during human pregnancy. Because of the toxicities found in animal studies with lixisenatide, it may be prudent to avoid insulin glargine; lixisenatide during human pregnancy until more data are available. Based on animal reproduction studies, there may be risks to the fetus from exposure to lixisenatide during pregnancy. Rat and rabbit studies have noted visceral closure and irregular skeletal ossification at systemic exposures that decreased maternal food intake and weight gain during gestation at doses 1-time and 6-times higher than the 20 mcg/day clinical dose, respectively, based on plasma AUC. Fetal abnormalities in animal studies of insulin have not been reported when insulin is used at doses similar to those that would be used in humans; however, high doses of insulin inducing maternal hypoglycemia have been associated with fetal toxicity such as pre- and post-implantation losses and visceral/skeletal abnormalities. Optimizing glycemic control before conception and during pregnancy appears to improve fetal outcome; this should include the avoidance of episodes of hypoglycemia as the toxic effects of maternal hypoglycemia on the fetus have been well-documented. In general, insulin requirements decline during the first trimester, increase during the second and third trimesters, and then decline significantly after delivery. Use caution when administering long-acting insulin products near term as insulin requirements may change rapidly and dietary carbohydrate intake may be unpredictable. Careful monitoring is required throughout pregnancy and during the perinatal period. During the perinatal period, careful monitoring of neonates born to mothers with diabetes is also recommended. Most experts, including the American College of Obstetrics and Gynecologists (ACOG) and the American Diabetes Association (ADA), recommend human insulin as the therapy of choice to maintain blood glucose as close to normal as possible during pregnancy in women with diabetes mellitus and gestational diabetes mellitus (GDM) requiring medical therapy; insulin does not cross the placenta.

There are no data on the presence of lixisenatide or insulin glargine in human milk during breast-feeding, the effects on a breast-fed infant, or the effects on human milk production. Endogenous insulin is present in human milk; insulin glargine is present in rat milk. A decision should be made whether to discontinue breast-feeding or to discontinue the drug, taking into account the importance of the drug to the mother. In lactating rats, lixisenatide and its metabolites had a low (9.4%) transfer into milk and negligible (0.01%) levels of unchanged lixisenatide peptide in the gastric contents of weaning offspring. If lixisenatide is discontinued and blood glucose is not controlled on diet and exercise alone, insulin therapy should be considered. Other oral hypoglycemics may be considered as possible alternatives during breast-feeding. Because acarbose has limited systemic absorption, which results in minimal maternal plasma concentrations, clinically significant exposure via breast milk is not expected. Also, while the manufacturers of metformin recommend against breast-feeding while taking the drug, data have shown that metformin is excreted into breast milk in small amounts and adverse effects on infant plasma glucose have not been reported in human studies. The American Academy of Pediatrics (AAP) regards tolbutamide as usually compatible with breast-feeding. Although other sulfonylureas have not been evaluated by the AAP, glyburide may be a suitable alternative since it was not detected in the breast milk of lactating women who received single and multiple doses of glyburide. If any oral hypoglycemics are used during breast feeding, the nursing infant should be monitored for signs of hypoglycemia, such as increased fussiness or somnolence.
