What Should I Know About Oxymetazoline (0.05% W/v), Including Its Uses, Dosing, And Safety?

Oxymetazoline is a nasal decongestant commonly used to relieve nasal congestion caused by colds, allergies, or sinusitis. It works by narrowing the blood vessels in the nasal passages, reducing swelling and congestion. Typically, it is available as a nasal spray with a concentration of 0.05% w/v.

For adults and children over 6 years, the usual dose is 1-2 sprays in each nostril every 10-12 hours, not exceeding 2 doses in 24 hours. It's important not to use it for more than 3 consecutive days to avoid rebound congestion, where symptoms worsen after stopping the medication.

Safety tips include avoiding use if you have certain conditions like high blood pressure or heart disease, and consulting a healthcare provider if you're pregnant or breastfeeding.
