2 Weeks Before Your Screening

Some of the medicines you take may need to be stopped or adjusted before your colonoscopy. You MUST call the doctor who ordered any of the following medicines at least 2 weeks before your colonoscopy.

  • If you take aspirin, take it and ALL other medications prescribed by your doctor. On the day of your colonoscopy, take your medications with a sip of water.

1 Week Before Your Screening

  • Do NOT take medicines that stop diarrhea – such as Imodium®, Kaopectate®, or Pepto Bismol®.
  • Do NOT take fiber supplements — such as Metamucil®, Citrucel®, or Perdiem®.
  • Do NOT take products that contain iron — such as multi-vitamins (the label lists what is in the product).
  • Do NOT take vitamin E.
  • Do NOT eat high-fiber foods — such as popcorn, beans, seeds (flax, sunflower, quinoa), multigrain bread, nuts, salad/vegetables, or fresh and dried fruit.
  • Buy your bowel preparation kit (MoviPrep) at your local pharmacy or drugstore pharmacy at least 5 days before your colonoscopy BUT DO NOT OPEN OR MIX THE SOLUTION until the day before your colonoscopy. If you do NOT follow the directions for when to start drinking the bowel preparation, your colonoscopy WILL be cancelled.

The Day Before Your Screening

  • Only drink clear liquids the ENTIRE DAY before your colonoscopy. Do NOT eat any solid foods. Drink at least 8 ounces of clear liquids every hour after waking up. The clear liquids you can drink include: water, apple or white grape juice; broth; coffee or tea (without milk or creamer); clear carbonated beverages such as ginger ale or lemon-lime soda; Gatorade® or other sports drinks (not red); Kool-Aid® or other flavored drinks (not red).
  • You may eat plain jello or other non-red gelatins or non-red popsicles.
  • Do NOT drink alcohol on the day before or the day of the procedure.
  • Prepare the Moviprep solution. The MoviPrep carton contains pouches and a disposable container for mixing. Follow the mixing instructions on the carton. Mix the MoviPrep solution no sooner than 24 hours before it will be used. Do not add ice, sugar or flavorings to the solution. Do not take more than the recommended dose or serious side effects could occur. You can refrigerate the preparation before drinking.

The Evening Before Your Screening

Step 1.

i. Start drinking MoviPrep at 6 PM the evening before your colonoscopy. Drink an 8-oz glass of the bowel preparation mixture every 15 minutes for a total of 4 glasses.
ii. Fifteen (15) minutes later, drink an 8-oz glass of clear liquids every 15 minutes for a total of 2 glasses.

Step 2.

i. Thirty (30) minutes later, drink an 8-oz glass of the bowel preparation mixture every 15 minutes for a total of 4 glasses.
ii. Fifteen (15) minutes later, drink an 8-oz glass of clear liquids every 15 minutes for a total of 2 glasses.

You may continue to drink clear liquids only until midnight. Do NOT eat or drink ANYTHING after midnight the night before your procedure or your procedure may be cancelled. This is for your safety so as to reduce the risk of having food or liquid in your stomach move into your lungs (aspiration) during the procedure.

Day Of Your Screening

  • Your bowel must be empty so that your doctor can clearly view your colon.
  • If you take aspirin, take it and ALL other prescribed medicines with a sip of water on the day of your colonoscopy.
  • Designated Driver on the Day of Your Exam: A responsible family member or friend MUST come with you to your colonoscopy and REMAIN in the endoscopy area until you are discharged! You are NOT ALLOWED to drive for 24 hours, take a taxi or bus home by yourself, or leave the Endoscopy Centre ALONE. If you do not have a responsible driver (family member or friend) with you to take you home, your exam cannot be done with sedation and the screening will be cancelled.
