Colonoscopy Prep for Morning Procedure (Arriving at Hospital before 10am) (Download PDF)
* 2 Days prior to procedure: Avoid high fiber foods such as corn, nuts, tomatoes, lettuce, bran cereals, etc. Click here 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. If you drink or consume red colored products, you may experience red colored bowel movements so this is not advised. You may have clear liquids up until the time of your procedure.
* Please note, the start times below are approximations. If you need
to move the start time up or back an hour or more, then adjust the
other times the same amount.
* At 4pm the Day prior to procedure: Take 1 Dulcolax tablet every 10 minutes with an 8 oz. glass of water until you have taken a total of 2 tablets (over the counter, no prescription needed).
Colon purge solution preparation: Follow the instructions on the colon purge solution for filling with water. Shake well. Do not add sugar or flavorings, unless given to you at the pharmacy. Do not add ice or chill solution, drink the purge solution at room temperature.
* At 6pm the Day prior to procedure: Begin drinking the colon purge solution. Drink an 8 oz. glass every 5-10 minutes (total of 8 glasses or half the total volume). Put the rest in the refrigerator for later. It is best to drink the whole glass quickly rather than sipping small amounts continuously.
Feelings of bloating are common after the first few glasses because of the large amount of fluid ingested. This is usually temporary and should disappear once bowel movements begin. If you experience nausea or cramping, stop drinking for 15 minutes. Try drinking warm tea, broth, or hard candy, and then begin again. Your stools should begin after the first 4-6 glasses. Continue drinking once the stools have begun. They should become more and more liquid and lighter in color.
* Take remaining purge solution out of the refrigerator 1/2 hour prior to drinking your second dose.
* At 9pm the Day prior to procedure: Start drinking the rest of the colon purge solution as above; continue until the solution is all gone. The prep is not complete until the stools are clear or light yellow water. * An alternative would be to drink this second dose of prep very early on the morning of the procedure. You would need to drink this at least 3-4 hours before you are due to arrive at the hospital. Drinking the second dose at this alternative time actually leads to a better overall prep.
