## Sinex (oxymetazoline) ### Overview Sinex is a nasal spray containing oxymetazoline, a topical alpha-adrenergic agonist that causes vasoconstriction of nasal mucosal vessels, reducing swelling and congestion. ### Primary Indications * Nasal congestion associated with the common cold, allergic rhinitis, or sinusitis. ### Adult Dosing * **Nasal Spray:** 2 sprays in each nostril every 10-12 hours as needed. * **Maximum:** Do not exceed 2 doses in a 24-hour period. ### Pediatric Dosing * **Children 6 to under 12 years:** 1 to 2 sprays in each nostril every 10-12 hours as needed. * **Children under 6 years:** Safety and efficacy have not been established. Use should be at the discretion of a healthcare provider. ### Dose Adjustments * No specific dose adjustments are typically required for renal or hepatic impairment. ### Contraindications * Hypersensitivity to oxymetazoline or any component of the formulation. * Use with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing MAOIs. ### Adverse Effects * **Common:** Nasal stinging, burning, dryness, sneezing, rebound congestion (rhinitis medicamentosa) with prolonged or excessive use. * **Less Common/Serious:** Increased blood pressure, headache, nervousness, insomnia, palpitations, dizziness. ### Key Drug Interactions * **MAOIs and other sympathomimetic agents:** Increased risk of hypertensive crisis. ### Monitoring * Monitor for signs of rebound congestion with prolonged use (typically beyond 3 days). * Monitor blood pressure, especially in patients with pre-existing hypertension or cardiovascular disease. ### Clinical Pearls * Limit use to a maximum of 3 consecutive days to prevent rebound congestion. * If congestion persists, reassess the diagnosis and consider alternative treatments. * Prime the pump before first use or if it hasn't been used for a while. *** _This information is intended for healthcare professionals.
