What is the maximum dose of hydroxyzine when used alone?

Hydroxyzine used as the sole sedative/anti-anxiety agent is dosed to limit total daily exposure to keep sedation manageable and reduce anticholinergic side effects. The maximum daily amount allowed when it’s used alone is 75 mg, typically achieved by giving up to 25 mg per dose three times a day. Higher daily totals raise the risk of excessive sedation, cognitive slowing, dry mouth, blurred vision, and potential cardiac effects, especially if other central nervous system depressants are involved. So, 75 mg is the upper limit for single-agent use because it caps the total daily exposure while still providing therapeutic effect. The other amounts reflect either a per-dose ceiling (25 mg) or a total that would exceed the recommended limit when used alone.
