How does this medication work? What will it do for me?
This is a combination product that contains three ingredients: picosulfate sodium, magnesium oxide, and citric acid. This medication is used to cleanse the bowel in preparation for a colonoscopy, barium enema x-ray exam, or surgical procedures that require a clean colon.
Picosulfate sodium belongs to the class of medications called stimulant laxatives, which activate the colon and stimulate the muscles in the colon to contract, causing a bowel movement. Magnesium oxide and citric acid combine to form magnesium citrate, which is an osmotic laxative that increases water in the colon. The combined effect clears out the bowels. Full bowel cleansing usually occurs within 3 to 6 hours or less.

The day before your procedure, dissolve one dose into 150 mL of water. The exact hour you should take this depends on what time your procedure is scheduled for, and your doctor will give you specific instructions. The second dose is dissolved in 150 mL water 6 to 8 hours later.
It is important to drink 1.5 L to 2 L of clear fluids (water; sports drinks; clear fruit juices such as apple, grape, or cranberry juice; broths) between doses: Drink about 250 mL of water each hour after each dose until the effects of the medication have worn off and bowel movements have stopped.
