What is Fexofenadine?
Fexofenadine is an antihistamine medication used to relieve allergy symptoms such as hay fever (allergic rhinitis) and hives (urticaria). It works by blocking histamine, a substance in the body that causes allergic reactions like itching, sneezing, a runny nose, and watery eyes. As a second-generation antihistamine, it is less likely to cause drowsiness compared to older antihistamines like diphenhydramine. Fexofenadine is available in tablets, capsules, and oral suspension forms.
