## Sinex (Oxymetazoline) ### Overview Sinex is a nasal spray containing oxymetazoline, an alpha-adrenergic agonist that causes vasoconstriction of nasal mucosal blood vessels, reducing swelling and congestion. ### Primary Indications Temporary relief of nasal congestion due to the common cold, hay fever, or other upper respiratory allergies. ### Adult Dosing * **Nasal Spray (0.05%):** 2 sprays in each nostril every 10-12 hours. Do not exceed 2 applications in a 24-hour period. ### Pediatric Dosing * **Children 6 years and older:** 2 sprays in each nostril every 10-12 hours. Do not exceed 2 applications in a 24-hour period. * **Children under 6 years:** Safety and efficacy not established. Consult a pediatrician. ### Dose Adjustments No specific dose adjustments are typically required based on renal or hepatic impairment. ### Contraindications * Hypersensitivity to oxymetazoline or any component of the formulation. * Patients currently taking or within 14 days of stopping a monoamine oxidase inhibitor (MAOI). ### Adverse Effects * **Common:** Nasal discomfort, stinging, burning, dryness, sneezing. * **Less Common:** Rhinitis medicamentosa (rebound congestion) with prolonged or excessive use, increased blood pressure, palpitations, insomnia, nervousness. ### Key Drug Interactions * **MAOIs:** Concomitant use or recent use (within 14 days) can cause severe hypertensive crisis. * **Other sympathomimetic agents:** May potentiate pressor effects. ### Monitoring * Monitor for signs of rebound congestion (rhinitis medicamentosa) with prolonged use. * Monitor blood pressure in patients with pre-existing hypertension, especially with frequent or prolonged use. ### Clinical Pearls * Limit use to a maximum of 3 consecutive days to prevent rebound congestion. * If nasal passages remain blocked, consider alternative therapies or consulting a healthcare provider. * Proper nasal spray technique is important: tilt head slightly forward, insert tip into nostril, spray while sniffing gently, and hold head over sprayed nostril for a moment. *** *This information is intended for healthcare professionals and is not a substitute for professional medical advice.
