This medication is a combination of polyethylene glycol 3350 and electrolytes and belongs to a class of medications called osmotic laxatives. It works by drawing and retaining water into the large colon. This softens the stool and stimulates the rhythmic movement of the muscles in the colon, leading to a bowel movement.
This medication is used to cleanse the bowel in preparation for a colonoscopy, barium enema x-ray exam, or surgical procedures that require a clean colon. You should expect the first bowel movement to occur approximately 1 hour after you start taking this medication. Full bowel cleansing usually occurs within 3 to 5 hours.
