How long does it take for MiraLAX to take effect?

Bowel movements usually begin within 1 hour of drinking the first dose, but it may take longer for some people. Don't worry if you don't start having bowel movements after drinking the first half of the MiraLAX. Continue to drink liquids and start the second half of the MiraLAX as instructed.

Does MiraLAX make you poop?

MiraLAX is an osmotic laxative. That means it draws water into the colon, which softens the stool and may naturally stimulate the colon to contract. These actions help ease bowel movements.
