oxymetazoline

Oxymetazoline is a topical nasal decongestant used to relieve nasal congestion caused by allergies, colds, or sinus issues. It works by constricting blood vessels in the nasal passages, which reduces swelling and opens up nasal airflow quickly. Typically available as a spray or drop, it provides fast relief—usually within minutes—and its effects can last several hours. However, it should be used cautiously and not for more than a few days, as prolonged use can lead to rebound congestion, where nasal stuffiness worsens. Always follow dosing instructions and consult a healthcare provider if needed.
