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.

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.
Reserpine: (Major) The vasoconstricting actions of oxymetazoline, an alpha adrenergic agonist, may reduce the antihypertensive effects produced by reserpine. 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.

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.
