A: Zyrtec-D is a combination tablet of an antihistamine (Zyrtec) and a decongestant (pseudoephedrine). Antihistamines help with sneezing, runny noses and drainage. Decongestants help relieve pressure and pain in the sinuses. Zyrtec or the antihistamine portion has a potential to cause some drowsiness and dry mouth. Sudafed (pseudoephedrine) can cause difficulty sleeping, nausea, and loss of appetite.
What is Zyrtec? Zyrtec (cetirizine) is an antihistamine that reduces the effects of natural chemical histamine in the body.

Zyrtec is also used to treat itching and swelling caused by chronic urticaria (hives). Zyrtec may also be used for purposes not listed in this medication guide.
