Dimenhydrinate is used to prevent and treat nausea, vomiting and dizziness caused by motion sickness when medication cannot be given by mouth. It is most effective when given to prevent motion sickness rather than as a treatment for symptoms that have already started. Dimenhydrinate injection should not be used in newborns because of an increased risk of side effects.Dimenhydrinate is an antihistamine. It is not known exactly how it treats motion sickness. It is thought to work by blocking a certain natural substance (acetylcholine) and preventing its effects on the inner ear. The inner ear helps maintain your sense of balance and position.Dimenhydrinate is also used to treat symptoms of other motion and balance problems such as feelings of dizziness/spinning (vertigo) and inner ear problems (e.g., Meniere's disease). It may also be used to treat nausea and vomiting due to surgery, radiation sickness, side effects of drug treatment, and other causes.
