1-3 days: The onset of MiraLAX (polyethylene glycol) is usually 1-3 days. Remember, it is an osmotic agent that draws water into the stool and hence makes it easier to have a bowel movement.

Osmotic laxative: If you remember from science class putting sugar or other dry compound in small amount of water and placing it in lager container of tap water the tap water would cross the plastic bag and dilute the sugar water......Miralax (polyethylene glycol) is an osmotic laxative it prevents water from being absorbed in the gastrointestinal tract thereby getting more water to the anus vice a dry poop.

Hours to days.: Miralax (polyethylene glycol) works by absorbing water from the colon allowing it to move easier through the bowel and pass the stool. It probably needs to be taken daily to be effective . It is not like milk of magnesia or citrate of mnagnesia, which should only take few hours to be effective.

Few days: not really laxative to induce bowel contractions but a nonabsorbable material that cause the stools to become softer, and lubricates the bowel to cause easier passage of stool

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.
