Hydroxyzine Side Effects
Although most people do not experience problems while taking hydroxyzine, side effects are possible. Based on limited information, common side effects with this medication may include dry mouth, drowsiness, and shakiness. While most problems are mild, some are potentially serious and should be reported to your healthcare provider right away, including hallucinations, seizures, and difficulty breathing.
Just like any medicine, hydroxyzine (Atarax®, Vistaril®) can cause side effects. However, not everyone who takes the medication will experience 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 hydroxyzine. Your healthcare provider can discuss a more complete list of hydroxyzine side effects with you.)
Some hydroxyzine side effects, while occurring infrequently, are potentially serious and should be reported to your healthcare provider. These include, but are not limited to:
- Signs of an allergic reaction, such as:
- An unexplained rash
- Unexplained swelling (especially of the lips, mouth, or throat)
- Wheezing or other breathing problems.
Bothersome Side Effects of Hydroxyzine
Hydroxyzine is a relatively "old" medication, approved before the United States Food and Drug Administration (FDA) required detailed information on potential side effects in the prescribing information for medications. Therefore, only vague information on possible hydroxyzine side effects was provided, with no specific percentages.
Based on this limited information, possible bothersome (but not usually dangerous) side effects of hydroxyzine include:
- Dry mouth (see Hydroxyzine and Dry Mouth)
