Fexofenadine and Pseudoephedrine

Fexofenadine (fex-oh-FEN-a-deen) is an antihistamine and pseudoephedrine (soo-doe-e-FED-rin ) is a decongestant. The combination of these two medicines is used to treat the nasal congestion (stuffy nose), sneezing, and runny nose caused by hay fever.

The combination of Fexofenadine and Pseudoephedrine is used to relieve hay fever and allergy symptoms, including runny nose; sneezing; stuffy nose; itchy throat; and red, itchy, tearing eyes. Fexofenadine is in a class of medications called antihistamines. It works by blocking histamine, a substance in the body that causes allergic symptoms. Pseudoephedrine is in a class of medications called decongestants. It works by drying up the nasal passages.

The combination of Fexofenadine and Pseudoephedrine comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken twice a day on an empty stomach. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Fexofenadine and Pseudoephedrine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Swallow the tablets whole; do not split, chew, or crush them.
