This medication is used to clean the intestine to prepare you for rectal or bowel examinations.This product is a combination of two laxatives, bisacodyl and PEG with electrolyte. Bisacodyl works directly on the large intestine to make you have bowel movements. It is known as a stimulant-type laxative. PEG with electrolyte works by holding water in the stool to cause watery bowel movements. It is known as an osmotic-type laxative.
