OVERVIEW
A medication used to temporarily relieve constipation and heartburn

As a Laxative: When taken in higher doses, magnesium hydroxide draws water into the intestines through an osmotic effect. This increased water content softens stool and stimulates bowel movements, typically within 30 minutes to six hours.
HOW IT WORKS
Magnesium hydroxide acts as an osmotic laxative. When ingested, it draws water into the intestines, which:
Softens the stool, making it easier to pass.medicalnewstoday.com+1mscenter.org+1
Increases the volume of the stool, which stimulates the muscles of the intestines to contract and move the stool along.
This combination of effects helps relieve constipation typically within 30 minutes to 6 hours after taking the medication.
