PEG (polyethylene glycol) with electrolyte is used to clean out the intestines before certain bowel exam procedures such as colonoscopy or barium enema X-rays. It is a laxative that works by drawing large amounts of water into the colon. This effect results in watery bowel movements. Clearing stool from the intestines helps your doctor to better examine the intestines during your procedure.
