<prompt> Answer this question truthfullyWhat type of laxative is polyethylene glycol PEG and how does it work?  <response>: <reason> Polyethylene glycol PEG is an osmotic laxative. It works by drawing water into the colon, which softens the stool and makes it easier to pass. Because PEG is a non-absorbable sugar, it remains in the colon and does not enter the bloodstream. This makes it a safe and effective option for treating constipation. PEG is available over-the-counter and by prescription, and is commonly used for short-term relief of constipation. If you are experiencing constipation, it is important to speak with your healthcare provider to determine the best treatment options for your individual needs.
