anger, irritable, mood swings, aggressive, changes in behavior, agitated

Caused intense rage, anger, and irritability. I thought I was going crazy - could not control anger, was always irritable and when confronted by anyone I had intense, incredible rage that I have never felt before. Mood changes stopped immediately after I stopped taking Zyrtec. .... Read More

swelling of eyelids, face or lips, itching, mood swings, fatigue, changes in behavior, depression, headache, dizziness

My doctor prescribed me this medication along with my nasal sprays. I stopped taking Zyrtec because my insurance no longer covered it, and I couldn't afford it at the time. It didn't take long to start experiencing the withdrawal side effects I'm on day 4 without the pill. I couldn't figure out why I was getting headaches, it itches all over my body. Especially my back , legs, arms and face. I had to do some research to see what was causing this. I'm much happier now that I'm off the pills. Do not take this medicine, it is not worth it. I can't wait for the side effects to go away. .... Read More

Several times I have attempted to stop taking Zyrtec and I would break out in this itch all over my skin that is just unbearable to deal with. I always thought it was my allergies that was causing this itch but I guess it just might be the medication. .... Read More

night terrors, insomnia, itching, weight gain, rash

It does help me with my allergies a lot, but the withdrawal symptoms after (severe itching, rashes/bumps) are not so awesome.
