Hydroxyzine

Hydroxyzine is a prescription medicine used for allergy relief and itching. It is sold under brand names such as Atarax, and it comes in tablet and lotion forms. As an antihistamine, it works by blocking histamine, a natural substance that helps cause allergy symptoms.

Hydroxyzine may be used for itching due to allergic skin reactions and other allergy symptoms. It can cause drowsiness, so use caution when driving or operating machinery. Alcohol and other medicines that cause sleepiness may increase this effect. Follow your prescriber’s directions, especially if you have glaucoma, trouble urinating, heart rhythm problems, or are pregnant or breastfeeding.
