how soon does miralax work

MiraLAX generally takes about 12 to 24 hours to start working, with most people experiencing a bowel movement within 1 to 3 days after taking it. However, in some cases, it can take up to 96 hours. The timing can vary depending on factors like dosage, severity and cause of constipation, existing health conditions, and individual digestion speed. MiraLAX works by drawing water into the colon to soften the stool and increase its volume, making it easier to pass. It does not usually cause immediate effects or sudden urgency like stimulant laxatives.
