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.

Because it takes about four hours to absorb and reach a steady level, scopolamine is a prevention medication, not a rescue one. Putting it on once the boat is already rocking and you feel sick is too late to help that wave of nausea. Apply early, before symptoms start.
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. The patches are water resistant and usually survive swimming and showering, but check yours after water activities on a multi-day trip. 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 nurse practitioner. 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 the patch at least 4 hours before you need it to start working, and ideally the evening before you board, so it is fully active when you sail. It takes time to absorb, so applying it as the boat leaves the dock is too late.
It takes about 4 hours to begin working after you apply it. That is why it is applied in advance rather than once symptoms start.
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. If it gets wet while swimming it usually stays on, but check it after water activities.
