sodium phosphate monobasic/dibasic - oral, OsmoPrep (cont.)
USES: This medication is used to clean out the intestines before a colonoscopy. Sodium phosphate is a laxative that works by drawing large amounts of water into the colon, causing you to have watery bowel movements. This cleans out the intestines so that your doctor can clearly view them during your colonoscopy.This medication should not be used for weight loss or constipation due to the possibility of severe side effects.
