Miralax (PEG 3350), polyethylene glycol powder alone without electrolytes is FDA approved for constipation. It is mixed in 8-12 ounces of any beverage and can be used daily. Because it lacks taste (no electrolytes) it has been used as a bowel cleanser for colonoscopy. Generally, 255 g of Miralax is combined with 64 oz of Gatorade for bowel cleansing prior to colonoscopy. While not FDA approved for this indication, it has been widely used and is an accepted alternative to Golytely in numerous endoscopy centers across the country.
