Please read this ENTIRE PAGE of INSTRUCTIONS carefully several days before the procedure.  You must follow the instructions exactly in order to cleanse your colon adequately.  If your colon is not properly cleaned out it may result in cancellation of your procedure.  Please review Colon Prep: Questions & Answers.


4 Days prior to procedure:
Avoid high fiber foods such as corn, nuts, seeds, tomatoes, lettuce, bran cereals, fruit skins, fresh or dried fruits, fiber/granola bars, etc.  Click on link for more examples on Low Fiber Diet.  Drink extra clear liquids all day.

1 Day prior to procedure:
You are to have Clear Liquids only the entire day before your procedure and are encouraged to drink liberally, at least 10 (8 oz.) glasses, throughout the day. Clear liquids include: broth, tea, plain Jell-o(without fruit), punch, Kool-Aid, Sprite, 7-up, clear juices (i.e. apple or cranberry) sports drinks, flavored waters or Popsicles.  DO NOT DRINK ANYTHING RED OR PURPLE since this may look like blood in the colon.  You may have clear liquids up until the time of your procedure.
