What is Dimenhydrinate

DimenhydrinateThe Generic name of this drug
Treatment SummaryDimehydrinate is a medication that helps to prevent nausea, vomiting, and dizziness caused by motion sickness. It is a combination of an antihistamine called diphenhydramine and 8-chlorotheophylline in a salt form. It works by blocking histamine receptors in the vestibular system and blocking adenosine receptors. When taken in large doses, it can cause hallucinations, excitement, incoordination, and disorientation. Dimehydrinate was approved by the FDA in 1972.

Effectiveness

How Dimenhydrinate Affects PatientsDimenhydrinate is a drug used to prevent and treat nausea, vomiting, or dizziness related to motion sickness. It works for 4-8 hours. Patients should be aware that this drug can cause drowsiness and should avoid drinking alcohol or taking other sedatives while taking it. People should also be careful when driving or operating heavy machinery.
How Dimenhydrinate works in the bodyDimenhydrinate works by combining two active ingredients, diphenhydramine and 8-chlorotheophylline. Diphenhydramine is thought to reduce dizziness by blocking certain receptors, while 8-chlorotheophylline may help to increase alertness by blocking adenosine receptors. The exact way these ingredients interact is not yet known.

Dimenhydrinate for Motion Sickness
I use this product to help me with travel anxiety. It's really effective when taken 30 minutes before the event (be it a car ride or plane flight). I find that it also helps me in general stressors and situations which would normally trigger my anxiety.

Dimenhydrinate for Motion Sickness
A couple years ago, I tried Dramamine before riding roller coasters at an amusement park and it really worked well for me. I usually get motion sickness easily, but I felt noticeably better throughout the day and after riding the coasters. next time i think i will try the less drowsy formula (meclizine).

Dimenhydrinate for Sensation of Spinning or Whirling
I had been feeling really off balance and unsteady, to the point where I was constantly nauseous and vomiting. Thankfully, my doctor diagnosed me with vertigo and prescribed dimenhydrinate. Since treatment, I haven't experienced any of those awful symptoms! I'm so grateful to be able to go about my life without that constant discomfort.
