How does this medication work? What will it do for me?

Magnesium citrate belongs to a class of medications called osmotic laxatives and purgatives. It works by drawing and retaining water into the large colon. This softens the stool and stimulates the rhythmic movement of the muscles in the colon, leading to a bowel movement.

Magnesium citrate is used for the short-term of relief of constipation, and to cleanse the bowels prior to certain procedures, such as a colonoscopy. A bowel movement usually occurs between ½ hour to 6 hours after taking magnesium citrate.
