Fexofenadine in the 50 ml form is typically available as a liquid suspension and is used to treat allergy symptoms like sneezing, runny or itchy nose, and itchy or watery eyes caused by hay fever or other seasonal allergies. It works by blocking histamine, a substance produced by the body during allergic reactions. This medication is also used to relieve symptoms of chronic urticaria (hives), such as itching and rash. As a second-generation antihistamine, Fexofenadine is less likely to cause drowsiness compared to first-generation antihistamines. The 50 ml suspension form is often prescribed for children or individuals who have difficulty swallowing tablets. It generally provides relief for up to 24 hours when taken as directed.
