Bowel preparation before a colonoscopy is extremely important. Good preparation allows a physician to thoroughly examine a colon. The bowels need to be completely and carefully cleaned so that the doctor can easily discover any potential problems. Polyps or other abnormalities may be harder to notice if the bowels aren’t prepped and emptied properly prior to the procedure.  You should consult the gastroenterologist that is performing your procedure for you about the details of your bowel preparation (solution, specific instructions) to ensure it is done correctly to allow for a better prep rather than relying on general instructions.  Do not discontinue any medications without speaking to your doctor.  Procedural preparations also change and evolve with time, so it is important to understand what preparation, solution, and instructions your doctor recommends now for the best preparation for your procedure.

1 Day Before Your GoLYTELY Colonoscopy Procedure:

  • Make sure your solution is refrigerated for use later in the day. Begin a clear liquid diet. You can have water, clear broth or bouillon, coffee or tea (no milk or creamer), Gatorade, Powerade, Pedialyte, carbonated and non carbonated soft drinks, Kool-Aid or other fruit flavored drinks, Jell-O, popsicles, and hard candy. No red or purple fluids are allowed.
  • Drink at least 8 glasses of water of clear liquids throughout the day.
  • At 5 PM: Begin drinking 3 liters of the GoLYTELY solution (75% of the bottle). Drink 8 ounces every 10 minutes until completed. If you vomit, wait 30 minutes.
    After that, begin drinking again, taking 6 ounces every 15 minutes.Rapidly drinking a glassful is better than sipping an ounce or two at a time. A straw may be helpful to use when drinking the solution to get it down easier. Bowel movements may begin to occur about one hour after drinking the first glass and may continue two to four hours after you finish the last glass.Feelings of bloating, nausea, and chills are common after the first few glasses. This is temporary and will soon disappear once bowel movements begin. If nausea becomes acute, stop drinking the solution for 30 minutes, then resume drinking every 15 minutes as before.
  • Refrigerate the remaining 1 liter (25%) of the GoLYTELY

The Day of the GoLYTELY Colonoscopy Procedure:

  • 5 hours before your appointment time: Drink the remaining 1 liter (the rest of the bottle) of GoLYTELY.
  • Continue a clear liquid diet, including water.
  • 3 hours before your appointment: Stop drinking liquids. (You may take your morning medicines with 4 ounces of water)
