How does hydroxyzine (Vistaril) work?
- The body releases histamine during several types of allergic reactions and, to a lesser extent, during some viral infections, such as the common cold. When histamine binds to its receptors on cells, it causes the cells to release chemical messengers that lead to sneezing, itching, and increased mucus production. Antihistamines, like histamine, bind to the histamine receptors. When they bind to the receptors, however, they do not stimulate the cells to release chemical messengers. In addition, they prevent histamine from binding and stimulating the cells. Hydroxyzine itself has no histamine-like activity. After ingestion, it is converted to its active form. The active form of hydroxyzine is a drug called cetirizine (Zyrtec). Although, both hydroxyzine and cetirizine act as antihistamines, hydroxyzine causes more sedation than cetirizine.
When was hydroxyzine (Vistaril) approved by the FDA?
- The FDA approved hydroxyzine in 1956.
Hydroxyzine (Vistaril) is a drug prescribed to treat itching caused by a variety of allergic conditions, nausea, vomiting, and alcohol withdrawal. Review drug interactions, and pregnancy and breastfeeding safety information prior to taking hydroxyzine.

An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it.

Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
