NuLYTELY Colonoscopy Prep

** Following these instructions correctly will help your colonoscopy prep and procedure go smoothly**

NuLYTELY® with electrolyte (also called PEG (polyethylene glycol) is used to clean out the intestines before colonoscopy procedures. It is a laxative that works by drawing large amounts of water into the colon resulting in watery bowel movements. Clearing stool from the intestines helps your doctor to better examine the intestines during your procedure.
