Uses


What is MiraLAX used for?

MiraLAX is an over-the-counter laxative that softens stool and makes it easier to have bowel movements. This medication is also used for bowel preparation, for example, before a colonoscopy.

There may be other uses of this medicine — your healthcare provider or pharmacist can provide medical advice and give you further MiraLAX drug information.

MiraLAX Mechanism of Action

MiraLAX works by drawing water into the stool. This softens the stool and makes it easier to pass during a bowel movement, thereby providing predictable constipation relief.

What is the dosage of MiraLAX?

MiraLAX is available as a powder in a bottle and single-dose packets. The dose of MiraLAX powder is 17 grams once a day to treat occasional constipation.
