What is the most effective medication for motion sickness?

• A. Oral scopolamine
• B. Dimenhydrinate
• C. Transdermal scopolamine
• D. Meclizine

Answer: (C)

Motion sickness prevention works best with an anticholinergic approach, and the transdermal scopolamine patch provides the most reliable, long-lasting protection. The patch delivers a steady amount of drug over about 72 hours, bypassing the digestive tract and first-pass metabolism, so you get consistent CNS exposure without the peaks and troughs you see with oral dosing. This makes it more effective for preventing motion sickness during long trips than taking an oral anticholinergic. Oral scopolamine can be effective but is more variable in absorption and often requires more frequent dosing, while dimenhydrinate and meclizine (antihistamines) help with symptoms but are typically less effective overall and tend to cause daytime drowsiness. The patch’s convenience and superior preventive efficacy explain why it’s considered the best option for motion sickness prevention. Apply behind the ear at least a few hours before travel, and keep it in place for up to three days. Be mindful of anticholinergic side effects, especially in older adults.
