Allegra Drug Information
Allegra® (fexofenadine hydrochloride) is a nonprescription antihistamine approved for the treatment of seasonal allergies and chronic hives and itching.
It works for these conditions by blocking the effects of histamine, chemicals in the body that can cause itching, sneezing, and irritation. Clinical studies show that people taking Allegra had an improvement in their hay fever symptoms (such as itchy or watery eyes, runny nose, and sneezing) and itching due to hives.
In order to help ensure a safe treatment process, you should talk to your healthcare provider before using this allergy medicine if you have kidney disease or are currently pregnant or breastfeeding.
Potential side effects of Allegra include respiratory tract infection, back pain, headache, middle ear infection, and coughing.
