What is Sutab?

Sutab is a prescription bowel preparation taken before colonoscopy to completely cleanse the colon of stool and debris so the procedure can be performed effectively. It contains sodium sulfate, magnesium sulfate, and potassium chloride in tablet form—a tablet-based alternative to liquid bowel prep solutions. The tablets work as an osmotic laxative by drawing large amounts of water into the intestinal tract, rapidly flushing the colon. It's taken as two split doses—one the evening before and one the morning of the colonoscopy—each with large amounts of water, and should not be taken by patients with kidney disease without medical supervision.

Osmotic bowel flush

The sulfate and chloride salt combination creates a strong osmotic gradient that draws fluid into the intestinal lumen, producing a high-volume watery diarrhea that rapidly and thoroughly cleanses the entire colon of stool and debris.

Tablet-based convenience

Sutab delivers the osmotic laxative effect through tablets rather than a large volume of liquid solution—reducing the unpleasant taste and volume challenges that make traditional liquid bowel preps difficult for many patients to complete.

Split-dose preparation

Divided into two doses taken the evening before and morning of colonoscopy, the split-dose schedule improves colon cleansing quality by timing the second dose closer to the procedure—while requiring adequate water intake to prevent dehydration and electrolyte imbalance.
