What is Allegra-D 24 Hour?
Allegra-D 24 Hour contains a combination of fexofenadine and pseudoephedrine. Fexofenadine is an antihistamine that reduces the effect of the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
The pseudoephedrine in Allegra-D 24 Hour is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
