My four year old daughter has been taking Zyrtec for six months. We've had severe emotional outbursts, signs of depression, and aggression to the point were we were strongly considering a psychologist.
This registry is a place to share positive or negative side effects of using Zyrtec. If you directly experienced a side effect while using Zyrtec, then we encourage you to enter it here. Please note that entries here are the experiences of individual users, and in no way means that you or anyone else will experience the same side effect, since the same medication affects people in different ways. Please always contact your physician.
