As part of a class of drugs called belladonna alkaloids, scopolamine patches (Transderm Scop®) can prevent nausea and vomiting caused by motion sickness, anesthesia, or surgery. This prescription medicine comes as a skin patch that is placed behind the ear at least four hours before the effect is desired. One patch can last for up to three days.
Scopolamine patches work by affecting certain areas of the brain, helping to prevent or suppress nausea. While most people tolerate the medicine well, side effects can occur and may include dry mouth, drowsiness, and dizziness.
