Hazardous Drugs Classification
NIOSH 2016 List: Group 2
NIOSH (Draft) 2020 List: Table 2
Observe and exercise appropriate precautions for handling, preparation, administration, and disposal of hazardous drugs.
Use double chemotherapy gloves and a protective gown. Prepare in a biological safety cabinet or compounding aseptic containment isolator with a closed system drug transfer device. Eye/face and respiratory protection may be needed during preparation and administration.

Injectable Administration

Visually inspect for particulate matter and discoloration prior to administration whenever solution and container permit. The solution is clear, colorless, and contains no particles. Do not use injections which are unusually viscous, cloudy, discolored, or if particles are present.
Do NOT mix liraglutide with insulin. When using liraglutide (Victoza) concomitantly with insulin, administer as separate injections. The 2 injections may be injected in the same body region, but the injections should not be adjacent to each other.
Liraglutide (Saxenda) for the treatment of obesity is not recommended in combination with insulin.
Diabetic medication or other medication 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, if available, or reserve the use of any pen to 1 patient only.

Subcutaneous Administration

Administer once daily at any time of day, independently of meals.
Liraglutide is available as a pre-filled pen.
Pen needles are not included and must be purchased separately.
Use liraglutide pen with Novo Nordisk disposable needles.
The liraglutide pen must be primed prior to the first use. See the pen user manual for directions.
Inject subcutaneously into the thigh, abdomen, or upper arm.
Double-check dosage prior to administration.
Press down on the center of the dose button to inject until 0 mg lines up with the pointer. Inject over 6 seconds to ensure the full dose is injected. Keep thumb on the injection button until the needle is removed from the skin.
Rotate administration sites with each injection to prevent lipodystrophy and cutaneous amyloidosis.
For patients who are self-administering liraglutide, adequate oral as well as written instructions on the use of the injector pen should be supplied before they self-administer a dose.
Missed dose: If a dose is missed, resume the once-daily regimen as prescribed with the next scheduled dose. Do not administer an extra dose or increase the dose to make up for the missed dose. If more than 3 days have elapsed since the last dose, reinitiate therapy at 0.6 mg once daily and retitrate the dose, to reduce the occurrence of gastrointestinal adverse reactions associated with reinitiation of treatment.
Storage: After initial use, the pen can be stored for 30 days at controlled room temperature (59 to 86 degrees F; 15 to 30 degrees C) or in a refrigerator (36 to 46 degrees F; 2 to 8 degrees C). Keep the pen cap on when not in use. Protect the pen from excessive heat and sunlight. Always remove and safely discard the needle after each injection and store the pen without an injection needle attached. This will reduce the potential for contamination, infection, and leakage while also ensuring dosing accuracy.

Medullary thyroid carcinoma (MTC), multiple endocrine neoplasia syndrome type 2 (MEN 2), thyroid cancer, thyroid C-cell tumors

Liraglutide is contraindicated in patients with a personal or family history of certain types of thyroid cancer, specifically thyroid C-cell tumors such as medullary thyroid carcinoma (MTC), or in patients with multiple endocrine neoplasia syndrome type 2 (MEN 2). Liraglutide has been shown to cause dose-dependent and treatment duration-dependent malignant thyroid C-cell tumors at clinically relevant exposures in both genders of rats and mice. A statistically significant increase in cancer was observed in rats receiving liraglutide at 8-times clinical exposure compared to controls. It is unknown whether liraglutide causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans. Cases of MTC in patients treated with liraglutide for diabetes have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and liraglutide use in humans. In clinical trials, there were 7 reported cases of papillary thyroid carcinoma in patients treated with liraglutide and 1 case in a comparator-treated patient (1.5 vs. 0.5 cases per 1,000 patient-years). Most of these papillary thyroid carcinomas were less than 1 cm in greatest diameter and were diagnosed after thyroidectomy, which was prompted by finding on protocol-specified screening with serum calcitonin or thyroid ultrasound. Patients should be counseled on the potential risk and symptoms of thyroid tumors (e.g. a mass in the neck, dysphagia, dyspnea or persistent hoarseness). Although routine monitoring of serum calcitonin is of uncertain value in patients treated with liraglutide, if serum calcitonin is measured and found to be elevated, the patient should be referred to an endocrinologist for further evaluation.

Saxenda, Victoza

Rx

Subcutaneous incretin mimetic (GLP-1 receptor agonist); used once daily; not a first-line therapy due to the boxed warning regarding rodent C-cell tumors and the uncertain risk to humans
Victoza product is used in adult and pediatric patients 10 years and older with type 2 diabetes mellitus (DM) and to reduce the risk of non-fatal and fatal cardiovascular events (e.g., myocardial infarction or stroke) in adults, if these patients also have cardiovascular disease
Separate product (Saxenda) used for weight reduction and maintenance in obese pediatric patients 12 years and older and obese adults or overweight adults with at least 1 weight-related comorbidity

For the treatment of type 2 diabetes mellitus as an adjunct to diet and exercise. Subcutaneous dosage (Victoza) Adults

0.6 mg subcutaneously once daily for 1 week, then 1.2 mg subcutaneously once daily, initially. May increase the dose after at least 1 week to 1.8 mg subcutaneously once daily if additional glycemic control is needed. The 0.6 mg dose is a starting dose intended to reduce gastrointestinal symptoms during initial titration and is not effective for glycemic control.[38653]

Children and Adolescents 10 to 17 years

0.6 mg subcutaneously once daily, initially. May increase the dose after at least 1 week to 1.2 mg subcutaneously once daily and then after at least 1 week to 1.8 mg subcutaneously once daily if additional glycemic control is needed.[38653]

For the reduction of cardiovascular mortality, non-fatal myocardial infarction, or non-fatal stroke in persons with type 2 diabetes mellitus and established cardiovascular disease. Subcutaneous dosage (Victoza) Adults

0.6 mg subcutaneously once daily for 1 week, then 1.2 mg subcutaneously once daily, initially. May increase the dose after at least 1 week to 1.8 mg subcutaneously once daily if additional glycemic control is needed. The 0.6 mg dose is a starting dose intended to reduce gastrointestinal symptoms during initial titration and is not effective for glycemic control.[38653]

For the treatment of obesity and for chronic weight management as an adjunct to reduced-calorie diet and lifestyle modifications.
NOTE: Liraglutide is indicated in adults with an initial body mass index (BMI) of 30 kg/m2 or more or 27 kg/m2 or more in the presence of other risk factors (e.g., hypertension, type 2 diabetes, or dyslipidemia) and pediatric patients age 12 years and older with a body weight more than 60 kg and an initial BMI corresponding to 30 kg/m2 for adults by international cut-offs.
Subcutaneous dosage (Saxenda) Adults

0.6 mg subcutaneously once daily for 1 week, initially. Then increase the dose by 0.6 mg/week to 3 mg subcutaneously once daily. Consider delaying dose escalation for 1 additional week if a dose increase is not tolerated. Discontinue use if the 3 mg dose is not tolerated; efficacy has not been established at lower doses. If weight loss is not at least 4% of baseline weight after 16 weeks, discontinue therapy. Pharmacotherapy should be offered as chronic treatment along with lifestyle modifications to persons affected by obesity when the potential benefits outweigh the risks. Short-term pharmacotherapy has not been shown to produce longer-term health benefits and cannot be generally recommended.

Children and Adolescents 12 to 17 years

0.6 mg subcutaneously once daily for 1 week, initially. Then increase the dose by 0.6 mg/week to 3 mg subcutaneously once daily. May lower dose to previous level if a dose increase is not tolerated during dose escalation; dose escalation may take up to 8 weeks. Discontinue use if the 2.4 mg dose is not tolerated; efficacy has not been established at lower doses. If weight loss is not at least 1% of baseline BMI after 12 weeks on the maintenance dose, discontinue therapy.

Children 7 to 11 years†

0.3 mg subcutaneously once daily for 1 week, initially. Then increase the dose by 0.3 mg/week to 1.2 mg subcutaneously once daily, and then increase dose by 0.6 mg/week to 3 mg subcutaneously once daily. In a small trial, pediatric patients (age 7 to 11 years) at Tanner stage 1 with obesity were randomized (2:1) to receive 7 to 13 weeks of treatment with liraglutide (n = 16) or placebo (n = 8). A significant decrease in BMI Z score from baseline to end of treatment (estimated treatment difference: -0.28; p = 0.0062) was reported. Body weight was not significantly decreased and may be due to the short duration of treatment.[64813]

Patients taking antidiabetic agents should be closely monitored for changes in glycemic control, specifically hyperglycemia, if protease inhibitor therapy is initiated.
Atazanavir; Cobicistat: (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.
atypical antipsychotic: (Moderate) Monitor blood glucose during concomitant atypical antipsychotic and incretin mimetic 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.

Benzoic Acid; Hyoscyamine; Methenamine; Methylene Blue; Phenyl 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.
Beta-blockers: (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.
Bismuth Subsalicylate: (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.
Bismuth Subsalicylate; Metronidazole; Tetracycline: (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.
Bortezomib: (Moderate) During clinical trials of bortezomib, hypoglycemia and hyperglycemia were reported in diabetic patients receiving antidiabetic agents. Patients taking antidiabetic agents and receiving bortezomib treatment may require close monitoring of their blood glucose levels and dosage adjustment of their medication.
Butalbital; Aspirin; Caffeine; Codeine: (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.

Candesartan; 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.
Captopril: (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.
Captopril; Hydrochlorothiazide, HCTZ: (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.
Carbonic anhydrase inhibitors: (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.
Chloroquine: (Major) Careful monitoring of blood glucose is recommended when chloroquine and antidiabetic agents, including the incretin mimetics, are coadministered. A decreased dose of the antidiabetic agent may be necessary as severe hypoglycemia has been reported in patients treated concomitantly with chloroquine and an antidiabetic agent.
Chlorpromazine: (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.
Chlorpropamide: (Moderate) Consider reducing the sulfonylurea dose when initiating liraglutide to reduce the risk for hypoglycemia. Patients receiving liraglutide in combination with a sulfonylurea may have an increased risk of hypoglycemia, including severe hypoglycemia.
Chlorthalidone; Clonidine: (Minor) Increased frequency of blood glucose monitoring may be required when clonidine is given with antidiabetic agents. Since clonidine inhibits the release of catecholamines, clonidine 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. Clonidine does not appear to impair recovery from hypoglycemia, and has not been found to impair glucose tolerance in diabetic patients.
Choline Salicylate; Magnesium 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.
Chromium: (Moderate) Chromium dietary supplements may lower blood glucose. As part of the glucose tolerance factor molecule, chromium appears to facilitate the binding of insulin to insulin receptors in tissues and to aid in glucose metabolism. Because blood glucose may be lowered by the use of chromium, patients who are on antidiabetic agents may need dose adjustments. Close monitoring of blood glucose is recommended.
Clarithromycin: (Moderate) The concomitant use of clarithromycin and antidiabetic agents can result in significant hypoglycemia. Careful monitoring of blood glucose is recommended.
Clonidine: (Minor) Increased frequency of blood glucose monitoring may be required when clonidine is given with antidiabetic agents. Since clonidine inhibits the release of catecholamines, clonidine 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. Clonidine does not appear to impair recovery from hypoglycemia, and has not been found to impair glucose tolerance in diabetic patients.
Codeine; Phenylephrine; Promethazine: (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.
Codeine; Promethazine: (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.
Corticosteroids: (Moderate) Monitor blood glucose during concomitant corticosteroid and incretin mimetic use; an incretin mimetic 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.
Cyclosporine: (Moderate) Patients should be monitored for worsening of glycemic control if therapy with cyclosporine is initiated in patients receiving antidiabetic agents, including liraglutide. Cyclosporine has been reported to cause hyperglycemia. It may have direct beta-cell toxicity; the effects may be dose-related.
Daclatasvir: (Moderate) Closely monitor blood glucose levels if daclatasvir 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 daclatasvir.
Danazol: (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.
Darunavir: (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.
Darunavir; Cobicistat: (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.
Darunavir; Cobicistat; Emtricitabine; Tenofovir alafenamide: (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.
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.
Disopyramide: (Moderate) Disopyramide may enhance the hypoglycemic effects of antidiabetic agents. Patients receiving this combination should be monitored for changes in glycemic control.
Elbasvir; Grazoprevir: (Moderate) Closely monitor blood glucose levels if elbasvir 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 elbasvir.
Enalapril, Enalaprilat: (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.
Enalapril; Hydrochlorothiazide, HCTZ: (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.
Eprosartan: (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.
Eprosartan; 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.
Esterified Estrogens; 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.
Ethotoin: (Minor) Ethotoin can decrease the hypoglycemic effects of incretin mimetics by producing an increase in blood glucose levels. Patients receiving incretin mimetics should be closely monitored 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.
Fibric acid derivatives: (Moderate) Monitor blood glucose during concomitant incretin mimetic and fibric acid derivative use; an incretin mimetic dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
Fluoxetine: (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.
Fluphenazine: (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.
Fosamprenavir: (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.
Fosinopril: (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.
Fosinopril; Hydrochlorothiazide, HCTZ: (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.
Fosphenytoin: (Minor) Fosphenytoin can decrease the hypoglycemic effects of incretin mimetics by producing an increase in blood glucose levels. Patients receiving incretin mimetics should be closely monitored 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.
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.

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.
Loop diuretics: (Minor) Loop diuretics, such as 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, including incretin mimetics. This interference can lead to a loss of diabetic control, so diabetic patients should be monitored closely if these drugs are initiated.
Lopinavir; Ritonavir: (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.

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.
Methazolamide: (Minor) Carbonic anhydrase inhibitors may alter blood sugar. Both hyperglycemia and hypoglycemia have been described in patients treated with acetazolamide.

Tobacco smoking is known to aggravate insulin resistance. Cessation of nicotine therapy or tobacco smoking may result in a decrease in blood glucose.
Nirmatrelvir; Ritonavir: (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.

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.

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 liraglutide. Tacrolimus has been reported to cause hyperglycemia. Furthermore, tacrolimus has been implicated in causing insulin-dependent diabetes mellitus in patients after renal transplantation. The mechanism of hyperglycemia is thought to be through direct beta-cell toxicity.
Tegaserod: (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.
Telmisartan; Amlodipine: (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.
Telmisartan; 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.
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) 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) 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.
Tipranavir: (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.
Tolazamide: (Moderate) Consider reducing the sulfonylurea dose when initiating liraglutide to reduce the risk for hypoglycemia. Patients receiving liraglutide in combination with a sulfonylurea may have an increased risk of hypoglycemia, including severe hypoglycemia.
Tolbutamide: (Moderate) Consider reducing the sulfonylurea dose when initiating liraglutide to reduce the risk for hypoglycemia. Patients receiving liraglutide in combination with a sulfonylurea may have an increased risk of hypoglycemia, including severe hypoglycemia.
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.
Trandolapril; Verapamil: (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.
Tranylcypromine: (Moderate) Monitor blood glucose during concomitant incretin mimetic and monoamine oxidase inhibitor (MAOI) use; an incretin mimetic dose adjustment may be necessary. Concomitant use may cause an increased blood glucose-lowering effect with risk of hypoglycemia.
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.
Triamterene; Hydrochlorothiazide, HCTZ: (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.
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.
Valsartan; 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.
Vonoprazan; Amoxicillin; Clarithromycin: (Moderate) The concomitant use of clarithromycin and antidiabetic agents can result in significant hypoglycemia. Careful monitoring of blood glucose is recommended.

Liraglutide is an incretin mimetic; specifically, liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist with 97% amino acid sequence homology to endogenous GLP-1 (7—37). GLP-1 (7—37) represents < 20% of total circulating endogenous GLP-1. Liraglutide 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. Liraglutide does not increase insulin secretion or suppress glucagon secretion at normal or low glucose concentrations.
 
GLP-1 is also a physiological regulator of appetite and caloric intake and the GLP-1 receptor is present in several areas of the brain involved in appetite regulation. Liraglutide acts to reduce body weight through decreased caloric intake; it does not increase 24-hour energy expenditure.

Liraglutide is given via subcutaneous administration. Liraglutide is more than 98% bound to plasma protein. After a single radioactive liraglutide dose was administered to healthy subjects, the major component in plasma was intact liraglutide for the initial 24 hours. The mean apparent volume of distribution after subcutaneous administration of a 0.6 mg and 3 mg dose of liraglutide is approximately 13 L and 20 to 25 L, respectively. The metabolism of liraglutide mirrors that of large proteins without a specific organ as a major route of elimination. After a radioactive liraglutide dose, intact liraglutide was not detected in urine or feces; only a minor part of the administered dose was excreted as metabolites in the urine (6%) or feces (5%). The mean apparent clearance after subcutaneous injection of a single dose of liraglutide is approximately 0.9 to 1.4 L/hour. Liraglutide is resistant to dipeptidyl peptidase-4 (DDP-4), the endogenous enzyme responsible for the degradation of GLP-1; this allows for a long half-life (13 hours) and once daily dosing.
 
Affected cytochrome P450 (CYP450) enzymes and drug transporters: None

Intravenous Route

The mean volume of distribution after IV administration is 0.07 L/kg.

Subcutaneous Route

After subcutaneous injection, liraglutide binds to albumin at the injection site, and after that is released slowly into circulation. Peak plasma concentrations are achieved in roughly 8 to 12 hours; after a 0.6 mg subcutaneous dose, mean peak concentration was 35 ng/mL and total area under the curve (AUC) was 960 ng x hour/mL. Liraglutide Cmax and AUC increased proportionally over the therapeutic dose range of 0.6 to 1.8 mg. At a dose of 1.8 mg, the average steady-state concentration over 24 hours was approximately 128 ng/mL. In obese patients (BMI 30 to 40 kg/m2), the average steady-state concentration over 24 hours was approximately 116 ng/mL. Similar absorption is achieved with subcutaneous administration of liraglutide in the abdomen, thigh, or arm. The absolute bioavailability of liraglutide after subcutaneous injection is approximately 55%.[38653] [58673]

Pregnancy

Liraglutide excretion into human milk is unknown. Consider the benefits of breast-feeding, the risk of potential infant drug exposure to liraglutide, and the risk of an untreated or inadequately treated condition.[38653] [58673] In lactating rats, liraglutide was excreted unchanged in milk at concentrations approximately 50% of maternal plasma concentrations; the human relevance of thyroid C-cell tumors observed in mice and rats is unknown.[38653] [58673] If liraglutide is discontinued in a lactating woman with type 2 diabetes mellitus (T2DM) 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.[46303] 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.[31407] [31408] [31409] Tolbutamide is regarded as usually compatible with breast-feeding.[27500] 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.[31568] 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.[46104] According to the American Association of Clinical Endocrinologists and American College of Endocrinology (AACE/ACE) Obesity Clinical Practice Guidelines, the use of liraglutide for weight reduction is not recommended in breast-feeding women.[62881]
