Description

Cetirizine and pseudoephedrine(se-TEER-a-zeen and su-do-a-FED-rin) is a combination of an antihistamine and a decongestant used to treat the symptoms of seasonal or yearly allergies. Antihistamines work by preventing the effects of a substance called histamine, which is produced by the body. Histamine can cause itching, sneezing, runny nose, and watery eyes. Decongestants produce a narrowing of blood vessels. This leads to clearing of nasal congestion, but it may also cause an increase in blood pressure in patients who have high blood pressure.
