Fexofenadine and Pseudoephedrine


The combination of fexofenadine and pseudoephedrine is used in adults and children 12 years of age and older to relieve the allergy symptoms of seasonal allergic rhinitis ('hay fever'), including runny nose; sneezing; congestion (stuffy nose); red, itchy, or watery eyes; or itching of the nose, throat, or roof of the mouth. Fexofenadine is in a class of medications called antihistamines. It works by blocking the effects of histamine, a substance in the body that causes allergy symptoms.
