How does this medication work? What will it do for me?
Dimenhydrinate belongs to a group of medications called antiemetics. This medication is used to prevent and treat motion sickness as well as nausea and vomiting associated with various conditions such as chemotherapy, radiation, and surgery. It is also used to treat nausea and spinning sensations (vertigo) due to Ménière's disease and other conditions that cause these symptoms.
Dimenhydrinate works to relieve or prevent nausea and vomiting by affecting the vomiting centre in the brain. Most people can expect some relief of nausea and vomiting within one hour of taking any form of dimenhydrinate. It works to relieve vertigo by affecting the brain and the inner ear.
