Can I take zyrtec (cetirizine) while pregnant? If not, what can I take to ease my allergies (sneezing, itchy eyes and ears, runny nose)?

Confirm. I would suggest a saline rinse for nose and eyes. It should be safe, but please check with your local pharmacy and OB. They have up to date computerized information. Using a HEPA filter at home and avoiding triggers will also help.
