Hydroxyzine (hydroxyzine) — Uses, Dosage, Side Effects & Safety

Drug class: Antihistamine (First-generation)

Overview

Hydroxyzine is a prescription antihistamine used to relieve symptoms of allergy, such as itching, hives, and rashes. It is also commonly prescribed to manage anxiety, tension, and to help with sleep problems caused by these conditions. In some cases, hydroxyzine is used as a sedative before or after general anesthesia. Hydroxyzine works by blocking the effects of histamine, a natural substance in the body that causes allergic symptoms. It also has calming effects on the brain, which can help reduce anxiety and promote relaxation. Key points for patients: Hydroxyzine can cause drowsiness, so avoid driving or operating heavy machinery until you know how it affects you. It should only be used as directed by your healthcare provider and is not recommended for long-term use for anxiety.
