How does this medication work? What will it do for me?
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.
This medication will start to take effect approximately one hour after administration if taken for a medical procedure, and approximately 2 to 4 days if taken for treatment of constipation.
This medication may be available under multiple brand names and/or in several different forms.
