Dimenhydrinate Tablets (Gravol) - Uses, Dosage and Side Effects

Dimenhydrinate marketed under brand names Dramamine, Driminate, Gravol, Gravamin, Vomex, Viabom, Dramin, Daedalon, Antimo and Vertirosan is an over-the-counter medication used to prevent nausea and motion sickness. Gravol is a medicine that is also used to relieve sleeping problems. It is most commonly used as tablets, although it is also available in liquid form. Chemically, dimenhydrinate is a salt of two drugs: diphenhydramine, and 8-chlorotheophylline, a chlorinated derivative of theophylline.
The effects of dimenhydrinate are very similar to those of diphenhydramine. The main differences are a lower potency, and a longer latency. 50 mg dimenhydrinate contains 27.2 mg of diphenhydramine, so it is less potent at equal doses. Also, dimenhydrinate must dissociate into diphenhydramine and its counterion in the body before it is active, so it produces effects more slowly than diphenhydramine. The drug typically takes a minimum of 4 hours to fully take effect.
