# Sinex (oxymetazoline) ## Overview Sinex is a nasal spray containing oxymetazoline, a topical alpha-adrenergic agonist. It acts as a vasoconstrictor to reduce swelling and congestion in the nasal passages. ## Primary Indications Temporary relief of nasal congestion due to the common cold, hay fever, or other upper respiratory allergies. ## Adult Dosing Instill 2-3 sprays in each nostril every 10-12 hours. Do not exceed 2 doses in a 24-hour period. ## Pediatric Dosing * **Children 6 to under 12 years:** Instill 2-3 sprays in each nostril every 10-12 hours. Do not exceed 2 doses in a 24-hour period. * **Children under 6 years:** Not recommended. Consult a pediatrician. ## Dose Adjustments No dose adjustments are typically needed based on renal or hepatic impairment for topical nasal use. ## Contraindications * Hypersensitivity to oxymetazoline or any component of the formulation. * Patients with narrow-angle glaucoma. * Patients who have undergone transsphenoidal hypophysectomy or have exposed basal dura. ## Adverse Effects Common: Nasal burning, stinging, dryness, sneezing, increased nasal discharge. Rebound congestion (rhinitis medicamentosa) with prolonged use. ## Key Drug Interactions Systemic absorption can occur, especially with overuse. Use with caution in patients taking MAO inhibitors or tricyclic antidepressants, as this may potentiate the pressor effects of oxymetazoline. ## Monitoring * Monitor for signs of rebound congestion (worsening nasal blockage) with prolonged use. * Monitor for systemic side effects such as increased blood pressure, palpitations, or nervousness, especially in patients with cardiovascular disease or those using other sympathomimetic agents. ## Clinical Pearls * Limit use to a maximum of 3 consecutive days to minimize the risk of rebound congestion. * Advise patients to blow their nose gently after application. * Store at room temperature. *** *This information is intended for healthcare professionals.
