Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

This medicine contains a bisacodyl tablet and also a PEG-3350 powder to mix into a solution. You will take the tablet first and then drink the solution once you begin having bowel movements.

Prepare the solution as follows:

• Mix the powder with 2 liters of water.
• Shake well until the powder dissolves completely.
• Add one of the supplied flavor packs if desired. Do not add other flavorings such as sugar, honey, juice, sweetener, or other beverages.
• Keep the solution at room temperature or in a refrigerator until you are ready to start drinking it. Do not keep beyond 48 hours after mixing.

After taking the tablets you should have a bowel movement within 1 to 6 hours.

Once you have a bowel movement, drink 8 ounces of the solution every 10 minutes. Drink each portion as quickly as possible rather than sipping it slowly.

If you have severe stomach discomfort, stop drinking the solution or drink it more slowly at longer intervals.

Watery bowel movements should begin within 1 hour after you start drinking the solution.

Be sure to finish the entire 2 liters of solution, following the schedule your doctor recommends.

Follow your doctor's instructions about the type and amount of liquids you should drink for at least 24 hours before and after your colonoscopy.
