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.
Claritin causes stomach problems, and Allegra causes headaches. I have been using Zyrtec for years now, and there are days when I take 5 or more 10mg doses to get relief. I had been using OTC sinus sprays for immediate relief, but have quit them, using only saline solution 2 or 3 times daily.
