What hydroxyzine used for?

Hydroxyzine is a prescription antihistamine with sedative effects. It’s used for several things, depending on the form (there are two main ones: hydroxyzine hydrochloride and hydroxyzine pamoate). Common uses include:

- Itching from allergic reactions (pruritus, hives, eczema)
- Short‑term relief of anxiety and tension (often as a premedication or during acute situations)
- Sedation before procedures or surgeries
- Nausea or vomiting in some settings (antiemetic)

It’s also sometimes used off‑label for short‑term sleep problems.

Important safety notes:
- Common side effects: drowsiness, dry mouth, dizziness, blurred vision, constipation
- Avoid alcohol and other central nervous system depressants while taking it
- May cause confusion or performance problems in older adults; use with caution in glaucoma, urinary retention, and certain other conditions
- Pregnancy and breastfeeding: discuss with a clinician

If you have a specific condition you’re considering it for, or you’re in a particular country, tell me and I can tailor the information (including typical indications in that setting).
