Scopoderm patches are a type of transdermal patch used to prevent and treat nausea and vomiting caused by motion sickness or postoperative conditions. They contain scopolamine, which is absorbed through the skin to block certain signals in the brain that cause nausea. These patches are typically applied behind the ear and can provide relief for up to 72 hours. Always follow the instructions for proper use and consult a healthcare provider if you have any concerns.
