Meclizine is an antihistamine that reduces the effects of natural chemical histamine in the body. Meclizine is used to treat or prevent nausea, vomiting, and dizziness caused by motion sickness. It is also used to treat symptoms of vertigo (dizziness or spinning sensation) caused by disease that affects your inner ear. Meclizine may also be used for purposes not listed in this medication guide.
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.
