In order for the CT colonoscopy examination to adequately evaluate your colon, it is essential that the colon be free of stool, which, if present, may obscure abnormalities such as colon cancer.  In addition, a clean colon is less likely to produce discomfort during the examination.  To obtain a clean colon, colonic cleansing is performed, starting the day prior to the procedure.  The keys to a successful colon preparation are a low residue diet, as outlined below, taking the prescribed cleansing medications and drinking plenty of fluids.

The following non-prescription medications are available from your local pharmacy and should be obtained prior to beginning the CT Colonoscopy preparation:

  • Magnesium Citrate – One (1) 10 oz bottle
  • Dulcolax (Bisacodyl) – Four (4) tablets (5 mgs. each)
  • Dulcolax (Bisacodyl) – One (1) suppository

Additionally, prior to beginning the CT prep, you must obtain one bottle of Barium mixture from any South Jersey Radiology office. You will only be drinking 8 oz which is half of the bottle. Please discard the remainder of the bottle.
