Otrivin nasal spray is used to relieve nasal congestion caused by colds, flu, and allergies. It helps open the airways by constricting the blood vessels in the nose, which reduces swelling and congestion and facilitates breathing.
Otrivin nasal spray is also used for sinusitis and allergic rhinitis. It works very quickly and relieves symptoms within minutes of use. It is recommended not to use it for long periods exceeding five days to avoid side effects such as nasal dryness or increased congestion after stopping. A doctor should be consulted if symptoms persist or worsen.
