## How should I take bisacodyl and PEG-3350?

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

Drink plenty of water before, during, and after your bowel cleanse. You may get dehydrated easily while using bisacodyl and PEG-3350.

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.

Swallow each tablet whole and do not crush, chew, or break it. Take with a full glass of water.

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.

Call your doctor if you cannot drink all of the solution as prescribed in time for your colonoscopy. The test may need to be rescheduled.

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

On the day of your colonoscopy, do not eat solid food or drink anything other than clear liquids.

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.

Store unopened bisacodyl and PEG-3350 at room temperature, away from moisture and heat.
