Citrodan Oral Solution is a laxative used primarily for the short-term relief of constipation and to cleanse the bowels before certain medical procedures, such as a colonoscopy. Each 300 mL bottle contains 15 g (50 mg/mL) of anhydrous magnesium citrate
Magnesium citrate works by drawing water into the large intestine, which softens the stool and stimulates bowel movements. Typically, a bowel movement occurs between 30 minutes to 6 hours after taking the solution
