Hydroxyzine is typically prescribed in relatively frequent doses throughout the day, under a clinician’s guidance. The most common patterns are:

• For anxiety: 50–100 mg taken four times daily, with a maximum of about 400 mg per day in adults. This means dosing could be spaced roughly every 4–6 hours during waking hours. The total daily limit helps reduce the risk of sedative or anticholinergic effects accumulating over the day.

• For itching (pruritus): commonly 25 mg taken three to four times daily, with a typical maximum around 400 mg per day. This regimen targets daytime to evening itch control and keeps levels steady to manage symptoms.
• For sedation around procedures: often 50–100 mg given before surgery, with possible additional dosing after the procedure depending on needs.

Important cautions

• Dosing should be tailored by a healthcare provider based on age, kidney function, liver function, other medications, and specific conditions.
• Older adults may require lower initial doses and slower titration due to increased sensitivity to sedative effects.
• Do not exceed the recommended daily maximum without explicit instruction from a clinician, and avoid combining with other sedatives or alcohol unless advised.
• If a dose is missed, do not double up unless explicitly directed by a clinician.

If you’re asking for a personal dosing plan, please consult your doctor or pharmacist. They can confirm whether hydroxyzine is appropriate for your situation and provide a precise dosing schedule based on your medical history and current medications.
