What is acrivastine and pseudoephedrine (Semprex-D)?
Acrivastine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of acrivastine and pseudoephedrine is used to treat runny or stuffy nose, sneezing, itching, watery eyes, and sinus congestion caused by allergies, the common cold, or the flu.
Acrivastine and pseudoephedrine may also be used for purposes other than those listed in this medication guide.
