Motion Sickness · Scopolamine patch
One scopolamine patch (Transderm Scop) lasts up to 3 days (72 hours). Apply it behind one ear at least 4 hours before you need it to work, ideally the evening before you board. For a trip longer than 3 days, remove the old patch and put a fresh one behind the other ear.

Scopolamine is used for prevention, not immediate relief. The label requires application at least four hours ahead, while CDC lists an onset of about six to eight hours. Plan ahead rather than waiting until nausea starts; follow your prescribed directions.
It happens: a patch peels in the shower, the pool, or the ocean. If it falls off, do not try to re-stick the old one. Throw it away, wash and dry the skin behind your other ear, and apply a new patch there, pressing firmly for 30 seconds. Limit contact with water while swimming or bathing because the patch can fall off. Scopolamine can cause confusion, disorientation and blurred vision; do not undertake underwater sports or other dangerous activities until you know how it affects you. Follow your product leaflet and clinician's instructions. This is exactly why we tell cruise travelers to pack a spare: one patch covers three days, but losing one mid-sailing should not end your protection. Ask for enough to cover your trip plus a backup.
The most common effects are a dry mouth, drowsiness, and sometimes blurred vision. Avoid alcohol, which adds to the drowsiness, and do not wear it if you will be operating a boat or flying a plane yourself. It is not for people with narrow-angle glaucoma, significant prostate or urinary-retention problems, or certain other conditions, which is what the online visit screens for.
If you have a cruise or boat trip coming up, Bidwell Health can review you for a scopolamine patch online and send it to your pharmacy when it is clinically appropriate.
It is a $45 asynchronous visit (no video, no membership) for adults in eligible states, reviewed by a licensed clinician. Request it at least a few days before departure so the patch is on hand and applied before you sail, and ask for a spare.
One scopolamine patch (Transderm Scop) lasts up to 3 days (72 hours). For a trip longer than 3 days, you remove the old patch and apply a new one behind the other ear. It is a prescription medication.
Apply at least 4 hours before motion exposure, following your prescription; applying the evening before may allow more lead time. It is not an immediate rescue treatment once seasickness starts.
The product label says to apply it at least 4 hours before the effect is needed; CDC lists an onset of about 6 to 8 hours for the patch. Plan ahead and follow your prescription rather than assuming full protection at exactly four hours.
If a patch falls off, throw it away, wash and dry the skin behind the other ear, and apply a new patch there. Do not try to re-stick the old one. Press a new patch firmly for 30 seconds. Limit water contact while swimming or bathing because the patch may fall off. Follow the product leaflet and avoid dangerous activities until you know how the medicine affects you.
Yes. Bidwell Health offers a $45 asynchronous online visit, no video and no subscription, for adults in eligible states who need a scopolamine patch for motion sickness, when clinically appropriate, sent to your local pharmacy.
Use one patch at a time, and do not cut it. Apply to clean, dry, hairless skin behind an ear at least 4 hours before motion exposure, following your prescription. For protection beyond 72 hours, remove the old patch before applying a new one behind the other ear. Wash hands after handling and the application site after removal. Remove it before an MRI. See the Transderm Scop instructions.
If a patch falls off, follow its replacement instructions rather than applying a second patch over it. Keep used patches away from children and pets; fold adhesive sides together for disposal. If you develop overheating or reduced sweating, remove the patch and contact a healthcare professional promptly; move somewhere cool. Confusion, collapse or severe heat illness needs emergency care. Risk can continue after removal. See the FDA heat warning.
