What is Sutab?

Sutab has a mix of magnesium sulfurate, potassium chloride, and sodium sulfurate. Magnesium and potassium, as well as sodium, are electrolyte minerals that naturally occur in body fluids. Sutab is a prescription medication that is used by adults in order to clean the colon prior to a colonoscopy. Sutab can cause diarrhea, which cleanses the colon. Cleaning your colon (bowel preparation) lets the interior of your colon be clearly seen through the colonoscopy.


Sutab could cause extreme dehydration, which could result in a serious electrolyte imbalance, seizures, or kidney failure.

Contact your physician if you have a fever, nausea, or vomiting and you aren't drinking enough fluids to support your bowel preparation, or if you experience a migraine, dizziness, or a decrease in the frequency of urination.
