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.
I tried to stop after allergy season, but would get a headache within 24 hours, so I continued the medication year round. For the last 8 months, I noticed if I went more than 24 hours without Zyrtec, I would have intense itching head to toe, so I would break down and take Zyrtec.
