What is scopolamine?

Scopolamine reduces the secretions of certain organs in the body, such as the stomach and intestines. Scopolamine also decreases nerve signals that trigger your stomach to vomit.

Scopolamine is used to prevent nausea and vomiting caused by motion sickness or from anesthesia given during surgery.

Scopolamine is also used to treat certain stomach or intestinal problems, muscle spasms, and Parkinson-like conditions.

Scopolamine may also be used for purposes not listed in this medication guide.
