While most side effects are minor, some are potentially serious and should be reported to your healthcare provider immediately, including seizures, hallucinations, and allergic reactions.
An Introduction to Vistaril Side EffectsAs with any medicine, Vistaril® (hydroxyzine) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Vistaril. Your healthcare provider can discuss a more complete list of Vistaril side effects with you.)
