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.
