Hydroxyzine, sold under the brand names Atarax and others, is a medication of the antihistamine type. It is used in the treatment of itchiness, anxiety, and nausea, including that due to motion sickness. It; however, is less preferred to newer antihistamines such as cetirizine or loratadine for hives. It is used either by mouth or injection into a muscle.

Common side effects include sleepiness, headache, and a dry mouth. Serious side effects may include QT prolongation. It is unclear if use during pregnancy or breastfeeding is safe. Hydroxyzine works by blocking the effects of histamine. It is a first generation antihistamine in the piperazine family of chemicals.

It was first made by Union Chimique Belge in 1956 and was approved for sale by Pfizer in the United States later that year. In the United Kingdom 28 doses cost less than a pound. In the United States the wholesale cost in 2018 was about 0.05 USD per dose. In 2017, it was the 99th most commonly prescribed medication in the United States, with more than seven million prescriptions.
