• What is this medication?

  POLYETHYLENE GLYCOL (pol ee ETH i leen; GLYE col) prevents and treats occasional constipation. It works by increasing the amount of water your intestine absorbs. This softens the stool, making it easier to have a bowel movement. It also increases pressure, which prompts the muscles in your intestines to move stool. It belongs to a group of medications called laxatives.

  This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
