User:Mr. Ibrahem/Dimenhydrinate

Dimenhydrinate, marketed as Dramamine and Gravol among others, is a medication used to treat motion sickness, nausea, and vertigo. While it maybe useful for allergies it has not been studied for this condition. It is a combination of diphenhydramine and 8-chlorotheophylline.

Common side effects include sleepiness, blurry vision, dry mouth, headache, confusion, and dizziness. Children may become hyperactive. Other side effects may include urinary retention and glaucoma. It has been taken by many pregnant women without any evidence of harm to the baby. Low doses when breastfeeding appear safe. Dimenhydrinate is a first generation antihistamine. It works mostly via the effects of diphenhydramine which blocks acetylcholine. The 8-chlorotheophylline is present to try to decrease the side effect of sleepiness.

Dimenhydrinate has been used medically since at least 1947 after being developed by G. D. Searle & Company. It is avaliable over-the-counter drug and as a generic medication. In the United States 120 tablets of 50 mg strength can be purchased for less than 10 USD as of 2020. It may be used recreationally for the high that large doses can cause.
