Allegra® (fexofenadine hydrochloride) is a medication that can be used to relieve symptoms of hay fever and to treat chronic hives and itching.
Allegra tablets are approved for use in adults and children six years of age and older. The oral solution is approved for use in younger children.
The drug works by blocking the effects of histamine, which can reduce allergy symptoms and alleviate itching due to hives. In clinical studies, people taking Allegra tablets for hay fever felt an improvement in symptoms, such as itchy or watery eyes, sneezing, and runny nose.
While most people tolerate this antihistamine well, side effects are possible. Some of the most common side effects that have been reported with Allegra include back pain, coughing, respiratory tract infection (such as the common cold or flu), and headache.
