How long does it take to poop on MiraLAX?

It can take MiraLAX 1-3 days to produce a bowel movement.



Which is better: MiraLAX powder or Dulcolax tablets?

Both MiraLAX and Dulcolax are FDA-approved over-the-counter laxatives that are used to treat occasional constipation. Both are also used as bowel prep medicines. MiraLAX is an osmotic laxative that works by drawing water into the stool, thus making it softer and easier to pass. Dulcolax is a stimulant laxative that increases intestinal activity to cause a bowel movement. Dulcolax works in 6-12 hours while MiraLAX can take 1-3 days to produce a bowel movement. However, MiraLAX is less likely to cause harsh side effects such as sudden urgency, upset stomach, and cramping. You may find one works better for you than the other.
