What is this medication for?
Sodium sulfate - potassium sulfate - magnesium sulfate belongs to the class of medications called osmotic laxatives. It is used for cleansing of the colon in preparation for a medical procedure called a colonoscopy in adults.
This medication works by causing water to accumulate in the intestines. This helps to soften the stool and produce a bowel movement more quickly. It also causes you to have diarrhea. Cleaning your colon helps your health care provider see the inside of your colon more clearly during your colonoscopy.
