Miralax

POLYETHYLENE GLYCOL 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.
