How to Prepare
What Do You Need to Do to Prepare for Your Colonoscopy?
Five (5) days before your colonoscopy, discontinue fiber supplements and any medication containing iron (Metamucil, Citrucel, multivitamins with iron, etc.).
Taking a blood thinner? You’ll need to contact your prescribing physician before discontinuing.
Below is a checklist for medications/prescriptions and items that you’ll need:
● 1 container of 238g MiraLAX (Polyethylene Glycol – generic name) – will be sent as a prescription
● 2 (two) 5mg Dulcolax Laxative tablets, not stool softeners (Bisacodyl – generic name)
● 1 10oz. bottle of Magnesium Citrate
● 64oz. of Gatorade (NO RED OR PURPLE)
Arrange for a driver the day of your procedure who will remain on the premises until you are discharged from the surgery center.
Three (3) days before your colonoscopy, begin a low-fiber diet. Avoid tough meats, whole grains, nuts, popcorn, seeds (i.e. flax, sunflower, quinoa), raw/seedy vegetables and fruits, and beans.

On the day before your colonoscopy, as soon as you wake up, you will begin a clear-liquid diet for breakfast, lunch, dinner, and any snacks. NO SOLID FOOD, NO DAIRY, and NO RED OR PURPLE COLORED PRODUCTS.

● At 8:00am, drink one (1) 10oz. bottle of Magnesium Citrate.
● At 4:00pm, start drinking 8oz. of the MiraLAX/Gatorade solution every 15 minutes, until the entire mixture is finished. (You should be done with this process around 6:00pm.)
● You may continue clear liquids until midnight.
