= Colonoscopy prep: Miralax (polyethylene glycol) is essentially a small dose of oral lavage widely prescribed for years in preparation for colonoscopy. The drug is not generally absorbed, so more taken means more of it available to promote bowel evacuation. An "overdose" of MiraLAX (polyethylene glycol) approaches the dose that optimally cleanses the colon for colonoscopy as something called "MiraLAX (polyethylene glycol) prep." don't "od" on your own--see doctor for right dose.

Laxative: Taking MiraLAX (polyethylene glycol) at more than a recommended dose causes more diarrhea. This is often used as a bowel prep prior to colonoscopy in different brand names. Many conventionally available bowel preps are similar to MiraLAX (polyethylene glycol) in chemical constituents, except the fact that they are larger volumes. You should stay hydrated and should go to er if you do not feel well.

Is dose-dependent...: The more MiraLAX (polyethylene glycol) you take the faster it works. As a once over-the-counter dosed laxative you may not see results for 3-4 days, but as a multi-dosed colonoscopy preparation (when used under doctor's advice) expect laxation within hours. As with any laxative however understand its mechanism of action, its risks, & treatment goals & make sure you are not missing obstruction, dysmotility, inflammation
