The Rhofade pump must be primed prior to its first use. With the pump in the upright position, depress the actuator until cream is dispensed and then pump 3 times. Discard the cream from priming actuations. NOTE: Priming the pump is only required before the initial use; tubes do not require priming.
Apply pea-size amount of cream as a thin layer to the entire face (i.e., forehead, cheeks, nose, and chin).
Avoid contact with eyes and lips.
Wash hands immediately following application.

Prior to initial use, remove the protective cap from the tip and prime the pump by depressing firmly several times.
Shake well before each use.
Hold upright with thumb at the base and the nozzle placed between the first and second fingers. Insert nozzle into nostril (do not tilt head). Fully depress rim with a firm, even stroke and sniff deeply.
Wipe nozzle clean after each use. To avoid spreading infection, the container should be used by only 1 person.

Visually inspect for discoloration. Do not use if solution changes color or becomes cloudy.
Remove contact lenses before instilling drops. Contact lenses may be reinserted 15 minutes after administering the dose.
If more than 1 ophthalmic medication is being used, the medications should be administered at least 15 minutes apart.
To avoid contamination, do not touch the tip of container to any surface.
To prevent infection, avoid the use of the container by more than 1 person.
Tilt head back, pull down the lower eyelid with a finger, and instill drop into the conjunctival sac of the affected eye.
For the 0.1% solution, each single patient-use container will provide enough medicine to treat both eyes (if needed) 1 time each day. There is some extra solution in each single patient-use container in case the drop misses the eye. Discard the single patient-use container and any unused solution immediately after dosing.
For the 0.025% solution, replace the cap after each use.[61735] [65687]

If these drugs are used together, closely monitor for changes in blood pressure.
Phenelzine: (Major) Oxymetazoline should generally not be used in patients taking non-selective monoamine oxidase inhibitors (MAOIs). The combination of an MAOI and a sympathomimetic drug, including decongestants given via topical, nasal, or ophthalmic routes, may rarely result in high blood pressure or in more serious cases, hypertensive crisis. Avoid use during and up to 2 weeks following discontinuation of the MAOI. Consider alternative treatments for the patient's condition.
Phenoxybenzamine: (Major) Caution is advised when administering phenoxybenzamine with oxymetazoline. Phenoxybenzamine, an alpha adrenergic blocker, would likely antagonize the sympathomimetic effects of oxymetazoline, alpha adrenergic agonists; thereby reducing the effectiveness of oxymetazoline. Clinicians should note that phenoxybenzamine has a long duration of action and its effects may persist for several days after it has been discontinued.
Phentolamine: (Major) Caution is advised when administering phentolamine with oxymetazoline. Phentolamine, an alpha adrenergic blocker, would likely antagonize the sympathomimetic effects of oxymetazoline, alpha adrenergic agonists; thereby reducing the effectiveness of oxymetazoline.

If these drugs are used together, closely monitor for changes in blood pressure.
Ramipril: (Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by angiotensin-converting enzyme inhibitors. If these drugs are used together, closely monitor for changes in blood pressure.
Rasagiline: (Moderate) The concomitant use of rasagiline and sympathomimetics was not allowed in clinical studies; therefore, caution is advised during concurrent use of rasagiline and sympathomimetics including non-prescription nasal and ophthalmic decongestants. Although sympathomimetics are contraindicated for use with other non-selective monoamine oxidase inhibitors (MAOIs), hypertensive reactions generally are not expected to occur during concurrent use with rasagiline because of the selective monoamine oxidase-B (MAO-B) inhibition of rasagiline at manufacturer recommended doses. One case of elevated blood pressure has been reported in a patient during concurrent use of the recommended dose of rasagiline and ophthalmic tetrahydrozoline, a drug similar to oxymetazoline. It should be noted that the MAO-B selectivity of rasagiline decreases as the dose increases above the recommended daily dose and interactions with sympathomimetics may be more likely to occur at these higher doses.
Sacubitril; Valsartan: (Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. If these drugs are used together, closely monitor for changes in blood pressure.
Selegiline: (Moderate) Use these drugs together with caution. Monitor blood pressure for hypertension during concomitant use of selegiline and oxymetazoline. Although oxymetazoline is used by nasal or ophthalmic routes, the use of these drugs together may produce substantial elevations in blood pressure. If a hypertensive crisis occurs, selegiline should be discontinued immediately and therapy to lower blood pressure should be instituted immediately.

(Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by calcium-channel blockers. If these drugs are used together, closely monitor for changes in blood pressure.
Telmisartan; Hydrochlorothiazide, HCTZ: (Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by angiotensin II receptor antagonists. If these drugs are used together, closely monitor for changes in blood pressure. (Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by diuretics. If these drugs are used together, closely monitor for changes in blood pressure.
Terazosin: (Major) Caution is advised when administering terazosin with oxymetazoline. Terazosin, an alpha adrenergic blocker, would likely antagonize the sympathomimetic effects of oxymetazoline, alpha adrenergic agonists; thereby reducing the effectiveness of oxymetazoline.
Testosterone: (Moderate) The drug interaction potential between intranasal testosterone (e.g., Natesto) and other intranasally administered drugs other than sympathomimetic decongestants is unknown. Therefore, concomitant use of intranasal testosterone with intranasal drugs other than sympathomimetic decongestants (e.g., oxymetazoline) is not recommended. Eighteen males with seasonal allergic rhinitis were treated with intranasal testosterone and randomized to receive oxymetazoline (30 minutes prior to intranasal testosterone) or no treatment. In general, serum total testosterone concentrations were decreased by 21-24% in males with symptomatic allergic rhinitis, due to the underlying condition. A mean decrease in AUC and Cmax (2.6% and 3.6%, respectively) for total testosterone was observed in males with symptomatic seasonal rhinitis when treated with oxymetazoline compared to untreated patients. Concomitant use of oxymetazoline does not impact the absorption of testosterone.

Oxymetazoline stimulates alpha-adrenergic receptors which cause intense vasoconstriction. When administered intranasally, this action promotes drainage and improves ventilation. The 0.025% ophthalmic solution causes vasoconstriction of conjunctival blood vessels thereby providing relief from minor eye irritations. In patients with rosacea, topical use can reduce facial erythema.
 
For the treatment of blepharoptosis, the 0.1% ophthalmic solution targets a subset of adrenoreceptors in the upper eyelid tarsal smooth muscle (Mueller's muscle). Stimulation of these alpha-adrenoceptors causes contraction of the Mueller's muscle and subsequent opening of the eye.

Oxymetazoline is administered via the topical, ophthalmic, and intranasal routes. After systemic absorption, the drug is approximately 57% bound to human plasma proteins. In vitro studies using human liver microsomes showed oxymetazoline was minimally metabolized, with 96% of the parent drug remaining intact after 120-minute incubation. Excretion has not been determined; however, the mean terminal half-life in healthy adults is 8.3 hours (range: 5.6 to 13.9 hours).[61733] [61734] [61735]
 
Affected cytochrome P450 isoenzymes and drug transporters: none

A pharmacokinetic study evaluating use of oxymetazoline topical cream in adults with rosacea identified measurable plasma drug concentrations in most subjects. After the first application, mean peak concentrations (Cmax) and exposure (AUC) were 60.5 +/- 53.9 pg/mL and 895 +/- 798 pg x hour/mL, respectively. After once daily applications for 28 days, the mean Cmax and AUC were 66.4 +/- 67.1 pg/mL and 1,050 +/- 992 pg x hour/mL, respectively; thus indicating little drug accumulation.[61733]

Ophthalmic Route
Following administration of a single drop of 0.1% ophthalmic solution in each eye (total oxymetazoline dose of 0.07 mg), the median time to reach peak oxymetazoline concentrations was 2 hours (range: 0.5 to 12 hours). The mean peak concentration (Cmax) and systemic exposure (AUC) were 30.5 +/- 12.7 pg/mL and 468 +/- 214 pg x hour/mL, respectively.

Data are limited regarding the use of oxymetazoline during pregnancy. It is unknown if the use of the drug in pregnant women is associated with an increased risk for major birth defects or miscarriages. In animal reproductive studies, no adverse developmental effects were observed after oral administration of oxymetazoline to pregnant rats and rabbits at systemic exposures up to 7- and 278-times the maximum recommended human ophthalmic dose, respectively. Data from 1 literature article found a potential association between second-trimester exposure to oxymetazoline nasal spray and renal collecting system anomalies. In another case, fetal distress was reported in a 41-week pregnant patient following repeated use of oxymetazoline nasal spray at a dose 5-times the recommended dose. The fetal distress resolved hours later, and prior to delivery of the healthy infant. Exposure to oxymetazoline topical cream has also been reported in 2 pregnant females. One pregnancy resulted in the delivery of a healthy child. The other pregnancy ended in spontaneous abortion, which was not considered related to drug exposure.

It is not known whether oxymetazoline is distributed into breast milk, or if the drug affects breast milk production. According to the manufacturer, caution should be exercised when administering it to women who are breast-feeding their infants. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.
