On the day of your CT Colonoscopy examination:

After removing the foil, the Ducolax (Bisacodyl) suppository should be inserted rectally 2 hours prior to arriving at the Radiology Department. While lying on your side with thigh elevated, insert the suppository into the rectum and gently push in as far as possible. Try to keep the suppository in for 20 minutes even if the urge for evacuation is strong. Bowel evacuation usually occurs within 15 to 60 minutes. You may take your normal medications with a small amount of water. Nothing else should be taken by mouth.

Please discuss this preparation with your doctor if you have chronic diarrhea, Inflammatory Bowel Disease such as Ulcerative Colitis or Crohns Disease or a large amount of rectal bleeding.
