Scopolamine is a medication primarily used to prevent nausea and motion sickness. It works by blocking certain signals in the brain that can cause these symptoms. Scopolamine is often administered as a patch placed behind the ear, allowing for gradual absorption into the bloodstream. In addition to its use for motion sickness, Scopolamine can also be used in some medical procedures to reduce saliva production and as part of anesthesia. It is important to use this medication under the guidance of a healthcare professional, as it can have side effects and interactions with other drugs.
