For vertigo, the typical adult dosage of meclizine is 25 to 100 mg per day, taken in divided doses. The exact frequency depends on the clinical response and your doctor's instructions, but it is commonly taken two or three times a day within that dosage range

. Key points on dosing for vertigo:

• Total daily dose: 25 to 100 mg
• Divided doses throughout the day (e.g., 2-3 times daily)
• Adjusted based on how you respond to the medication
• Follow your doctor's prescription carefully

For motion sickness, the dosing is different-usually a single dose of 25 to 50 mg taken 1 hour before travel, with no more than one dose every 24 hours

• You can take meclizine multiple times a day (usually 2-3 times) within a total daily dose of up to 100 mg.

Do not exceed the prescribed amount or frequency without medical advice, and consult your healthcare provider for personalized dosing and duration
