Fexona Oral Suspension is an antihistamine medication used for the relief of allergy symptoms. It contains Fexofenadine Hydrochloride, which blocks the action of histamine—a substance responsible for allergic reactions. This suspension is particularly effective for managing symptoms of seasonal and perennial allergic rhinitis, as well as chronic idiopathic urticaria (hives). It alleviates symptoms such as sneezing, runny nose, itchy eyes, and itching.
