Meclizine 25 mg (milligrams) is a generic medication to treat symptoms of motion sickness—nausea, vomiting and dizziness—and is available as a chewable tablet or capsule.

If you are predisposed to motion sickness, the Mayo Clinic recommends taking 25 to 50 mg of meclizine approximately one hour prior to travel 2. Thereafter, the dose may be repeated every 24 hours as needed.
If you are experiencing serious medical symptoms, seek emergency treatment immediately.
