Afrin drops are used as a nasal decongestant, helping to relieve nasal congestion caused by colds, allergies, or sinusitis. It works by constricting the blood vessels in the nose, which reduces swelling and congestion and facilitates breathing. It is used by spraying it into the nostrils as needed.
Afrin should not be used for long periods to avoid the rebound effect of congestion or severe nasal dryness. It is also recommended not to use it for more than five consecutive days, and the doctor or pharmacist’s instructions should be followed to avoid side effects such as itching or irritation in the nose.
