Dimenhydrinate is used to prevent and treat nausea, vomiting, and dizziness caused by motion sickness. Dimenhydrinate is in a class of medications called antihistamines. It works by preventing problems with body balance.
Dimenhydrinate comes as a tablet and chewable tablet to take by mouth with or without food. To prevent motion sickness, the first dose should be taken 30 minutes to 1 hour before you travel or begin motion activity. Adults and children older than age 12 may usually take dimenhydrinate every 4 to 6 hours as needed to prevent or treat motion sickness. Children under age 12 may usually be given dimenhydrinate every 6 to 8 hours as needed to prevent or treat motion sickness. Follow the directions on the package carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dimenhydrinate exactly as directed. Do not take more or less of it or take it more often than directed by the package label.
Do not give dimenhydrinate to children younger than 2 years of age unless your doctor has told you to do so.
Dimenhydrinate is also sometimes used to treat Meniere's disease (condition of the inner ear which causes extreme dizziness, loss of balance, ringing in the ears, and hearing loss) and other inner ear problems. Talk to your doctor about the risks of using this medication for your condition.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
