Patient Education

Polyethylene glycol-electrolyte solution (PEG-ES)


Polyethylene glycol-electrolyte solution (PEG-ES) is used to empty the colon (large intestine, bowel) before a colonoscopy (examination of the inside of the colon to check for colon cancer and other abnormalities) or barium enema (a test in which the colon is filled with a fluid and then x-rays are taken) so that the doctor will have a clear view of the walls of the colon. PEG-ES is in a class of medications called osmotic laxatives. It works by causing watery diarrhea so that the stool can be emptied from the colon. The medication also contains electrolytes to prevent dehydration and other serious side effects that may be caused by fluid loss as the colon is emptied.
