(Please read carefully)

These instructions use a split-dose (two-dose) regimen, which has been shown to cleanse the colon (lower intestine) better than other methods. The cleaner the colon, the less likely an exam would have to be repeated earlier than usual. Most importantly, a cleaner colon increases the chances of finding any significant abnormalities, such as polyps.

For some patients, this split-dose regimen may require staying up late into the evening or awakening early in the morning to complete the preparation with the second dose. We know this may be inconvenient, but it is very important to clean the colon as best as possible.

The exact timing of the early evening (5-6pm) first dose is not as important as the timing of the second. The most effective cleansing occurs when the second dose is taken 6 hours before the colonoscopy. Please finish the preparation and all clear liquids 4 hours before the examination.

Tips: Alcohol-free baby wipes, Vaseline, over-the-counter hydrocortisone creams, hemorrhoid treatments, all may be used to ease skin irritation. If you feel nauseous or vomit, rinse your mouth with water, take a 15 minute break, and then continue to drink the solution. Even if you are sitting on the toilet, continue to drink the solution as per instructions.
