Sodium/potassium/magnesium sulfate solution - oral
Sodium/potassium/magnesium sulfate solution is used to clean out the intestines before a certain bowel exam procedure (colonoscopy). It is a laxative that works by drawing large amounts of water into the colon. This causes watery bowel movements. Clearing stool from the intestines helps your doctor to better examine the intestines during your procedure.
