Zyrtec Anxiety Reviews

Sun, 28 Mar 2010
I took Zyrtec for a week and while it does solve my allergy issues, it makes me a raving lunatic. Severe aggression, mood swings, and nightmares are the norm for me n this medicine. I would not recommend it if you are taking any anti Anxiety or anti depressants.
