Meclizine Dosage: An Introduction

There is only one standard recommended dose for non-prescription meclizine hydrochloride (Bonine®, Dramamine® Less Drowsy Formula). For the prescription version (Antivert®), the dose that your healthcare provider recommends will vary, depending on the medical condition being treated.
As is always the case, do not adjust your dosage unless your healthcare provider specifically instructs you to do so.

Dosing for Non-Prescription Meclizine

The recommended non-prescription meclizine dosage for preventing and treating motion sickness in individuals 12 years old and older is one or two tablets (25 to 50 mg) once daily or as directed by your healthcare provider. Meclizine usually works best if you take it before motion sickness symptoms begin, although you can expect some relief even if you wait until symptoms develop.

For preventing and treating motion sickness, the standard prescription meclizine dosage is 25 to 50 mg taken one hour before embarkation, repeated every 24 hours if necessary.
