Emsam (generic: selegiline) is a prescription medication used to treat depression in adults.  Emsam belongs to a group of drugs called monamine oxidase (MAO) inhibitors, which affect communication between brain cells by increasing amounts of certain natural substances needed for mental balance.

This medication comes in the form of a skin patch. It is applied once a day to the upper chest or back, upper thigh, or upper arm.

Common side effects of Emsam include redness in the application area, a large and sudden increase in blood pressure (hypertensive crisis), and low blood pressure (hypotension).  Do not drive or operate machinery until you know how Emsam will affect you.
