How far in advance should you place the anti-motion patch prior to getting underway?

• A. 1 hour
• B. 2 hours
• C. 8 hours
• D. 4 hours

Answer: (D)

Key idea: medicines delivered through a transdermal patch need time to reach effective levels in your bloodstream before they can protect you from motion sickness. The anti-motion patch works by releasing medication steadily through the skin, but it doesn’t act instantly. It typically takes about four hours for the drug to begin providing protection, with full or steady protection developing after that and lasting for a day or two. So placing the patch four hours before you get underway ensures you’re protected right as you depart, rather than waiting and risking seasickness during those initial hours. Placing it much earlier isn’t necessary since the protective effect is already achieved by four hours, and waiting only one or two hours wouldn’t give enough lead time for the patch to take effect. Eight hours before departure would still work, but four hours is the standard lead time that aligns with how the patch delivers its dose.
