Hydroxyzine max dose per day?

Typically, the maximum recommended daily dose of hydroxyzine in adults is 400 mg/day. Dosing is usually divided throughout the day depending on the reason it's being taken:

- For anxiety: 50–100 mg every 4–6 hours as needed, up to a total of 400 mg/day.
- For itching (pruritus): 25–50 mg every 6–8 hours, up to 400 mg/day.
- For short-term sedation/pre-procedure use: 50–100 mg as a single dose.

Notes and safety:
- There are two salt forms (hydroxyzine HCl and hydroxyzine pamoate); the 400 mg/day limit generally applies to adults regardless of the salt form.
- In elderly individuals, or those with liver disease, start low and go slow (often MUCH lower than 400 mg/day) due to greater sensitivity to drowsiness and confusion.
- Avoid alcohol and other CNS depressants while taking hydroxyzine.
- Do not exceed the prescribed dose; talk to your clinician if symptoms persist or you think you need more.

If you want, tell me your age and the reason you’re taking hydroxyzine (anxiety, itching, etc.), and I can tailor the guidance more specifically.
