Fexofenadine is an antihistamine medication commonly used to relieve allergy symptoms such as sneezing, runny nose, and itchy eyes. It works by blocking the action of histamine, a substance in the body that causes allergic reactions. Fexofenadine is often prescribed for seasonal allergies and can help improve overall comfort during allergy season. This medication is available in various forms, including tablets and liquid, and is typically taken once or twice a day. Unlike some other antihistamines, Fexofenadine is less likely to cause drowsiness, making it a preferred choice for many individuals who need to remain alert while managing their allergy symptoms.
