Meclizine is used in adults and children aged 12 years and older to treat or prevent nausea, vomiting and dizziness caused by motion sickness.

Meclizine is also used in adults to treat symptoms of vertigo (dizziness or spinning sensation) caused by disease that affects your inner ear.

Meclizine is most effective if taken before symptoms appear.

Use meclizine only as directed. Tell your doctor if you use other medicines or have other medical conditions or allergies.

You should not take this medication if you are allergic to meclizine.

Before you take this medicine, tell your doctor if you have liver or kidney disease, asthma, glaucoma, an enlarged prostate, or urination problems.

Meclizine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Drinking alcohol can increase certain side effects of meclizine.

Cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression or anxiety can add to sleepiness caused by meclizine.

Take meclizine exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Swallow the tablet whole and do not crush, chew, or break it.

You must chew the chewable tablet before you swallow it.

To prevent motion sickness, take meclizine about 1 hour before you travel or anticipate having motion sickness. You may take meclizine once every 24 hours while you are traveling, to further prevent motion sickness.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

Avoid driving or hazardous activity until you know how meclizine will affect you. Your reactions could be impaired.

Avoid drinking alcohol. Drinking alcohol with this medicine can cause side effects.

Get emergency medical help if you have signs of an allergic reaction to meclizine: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Common meclizine side effects may include:

• drowsiness;

• dry mouth;

• headache;

• vomiting; or

• feeling tired.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Using meclizine with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

Sometimes it is not safe to use certain medicines at the same time. Some drugs can affect your blood levels of other drugs you use, which may increase side effects or make the medicines less effective.

Other drugs may interact with meclizine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all other medicines you use.

Keep all appointments with your doctor.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
