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 began taking Zyrtec in March to battle seasonal allergies and did not realize until today all the horrible side effects I have been experiencing are from this pill! I take 1 Zyrtec at night, right before bed due to the extreme drowsiness it causes if I take it during the day. I am a certified nutritionist and adhere to an extremely regimented diet and exercise plan. I have a ton of self control when it comes to diet and exercise and typically maintain a weight of 115 lbs.
