Macrogol, also known as polyethylene glycol (PEG), is used as a medication to treat constipation in children and adults.[1] It is taken by mouth.[1] Benefits usually occur within three days.[2] Generally it is only recommended for up to two weeks.[3] It is also used as an excipient.[4] It is also used to clear the bowels (known as "bowel prep") before a colonoscopy,[1] when the onset of the laxative effect is more rapid, typically within an hour.[5]
Side effects may include increased bowel gas, abdominal pain, and nausea.[1] Rare but serious side effects may include an abnormal heartbeat, seizures, and kidney problems.[6] Use appears to be safe during pregnancy.[7][1] It is classified as an osmotic laxative.[2] It works by increasing the amount of water in the stool.[3]
Macrogol came into use as a bowel prep in 1980 and was approved for medical use in the United States in 1999.[8][9][10] It is available as a generic medication and over the counter.[1][11] In 2021, it was the 226th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[12][13] It is also formulated together with electrolytes.[14] In 2021, the combination with electrolytes was the 295th most commonly prescribed medication in the US, with more than 500,000 prescriptions.[12][15]
