Meclizine is used to prevent and treat nausea, vomiting, and dizziness caused by motion sickness. It is most effective if taken before symptoms appear.

Meclizine comes as a regular and chewable tablet and a capsule. For motion sickness, meclizine should be taken 1 hour before you start to travel. Doses may be taken every 24 hours if needed. For dizziness caused by an ear condition, follow your doctor's directions. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take meclizine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The chewable tablets may be chewed or swallowed whole. - "Meclizine"
