motion sickness
"If I could give this drug a negative rating, I would. PLEASE be careful taking it. I sought the patch to use on 6-day cruise after reading that it was more effective than meclizine. Meclizine is a JOY compared to scopalamine. On patch, I was @ the ship's infirmary every day with low bp and feeling overheated (cruise was in Canada during fall - not warm weather!) Wicked, constant headache, nausea and could barely keep eyes open for entire trip. Ruined vacation. Disembarked and went straight to ER. Was completely dehydrated. ER doc informed me of documented instances of scopolamine psychosis. VERY dangerous med, here!"
