Prep Instructions

  • Mix the first entire 238 gram bottle of Miralax with 64 ounces of Gatorade, Powerade, or Crystal Light in a large pitcher.  You may use any other clear liquid you choose as well.  Stir.  We recommend chilling the mixture. You may add ice.
  • At 2 PM, start drinking your chilled Miralax mixture. Plan to consume ½ of the mixture. The start time for this may be varied according to your personal circumstances. 
  • You should pace yourself to drink an eight-ounce glass of the mixture every 10-15 minutes, until you have finished ½ of the mixture. 
  • Expect to move your bowels at least 5-10 times, although some people do not have multiple bowel movements after this initial dose of preparation. It usually takes about 30-60 minutes after drinking the Miralax solution to begin having bowel movements. You may notice some bloating or cramping at the beginning of the preparation, but this will usually improve once the bowel movements begin. 
  • At 7 PM, consume the rest of the Miralax mixture. 
  • Bowel movements should resume within 30 minutes to one hour.  Expect to move your bowels at least 10-15 times.

 

DAY OF COLONOSCOPY

  • Mix the second entire 238 gram bottle of Miralax with 64 ounces of Gatorade, Powerade, or Crystal Light in a large pitcher.  You may use any other clear liquid you choose as well.  Stir.  We recommend chilling the mixture. You may add ice.
  • 8 hours before the test is scheduled, again start drinking your chilled Miralax mixture. Plan to consume ½ of the mixture. 
  • You should pace yourself to drink an eight-ounce glass of the mixture every 10-15 minutes, until you have finished ½ of the mixture. 
  • Bowel movements should resume within 30 minutes to one hour.  Expect to move your bowels at least 10-15 times.
  • 5 hours before the procedure time, consume the rest of the Miralax mixture. 
  • You should pace yourself to drink an eight-ounce glass of the mixture every 10-15 minutes, until you have finished ½ of the mixture. 
  • Bowel movements should resume within 30 minutes to one hour.  Expect to move your bowels at least 10-15 times.
  • By the end of your preparation, your stool should become a clear, yellow tinged fluid.  If the stool coming out is not clear, please drink an additional 1-litre of water or another clear fluid approximately 3 ½ hours prior to your procedure time.
  • You may continue to drink clear fluids until 3 hours before the test is scheduled, but then nothing by mouth after that.  


HOW DO I KNOW IF MY PREP IS ADEQUATE?

The stool should be watery in consistency and should be a clear, yellow-tinged fluid without stool particles. Digestive secretions will continue to “tint” the stool yellow. If you are concerned that there are still stool particles present, you can self-administer one or two saline enema laxatives (these are available in pharmacies without prescription as 4.5 fluid ounce enemas) prior to leaving home for the procedure. If your prep is inadequate, the physician may not be able to visualize the entire colon adequately.

  • Make sure you know where your procedure will be performed.
  • Please arrive 1 hour in advance of your scheduled procedure time to allow time to complete the necessary paperwork.
  • Please bring a photo ID.
  • Please bring current insurance card, if applicable.
  • If for any reason you need to cancel your procedure, please call your doctor at the number provided to you. You must call at least 48 hours in advance to allow other patients to be scheduled for procedures.
