Prep Instructions

  • At 6 PM, drink one bottle of clenpiq.
  • Clenpiq is ready for you to drink from the bottle. It does not need to be mixed or diluted.
  • Do not refrigerate or freeze clenpiq.
  • Drink an additional 5 cups (8 oz each) of water or clear liquids.
  • 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 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.
  • The time of this dose may be adjusted to suit individual schedules.


  • Six hours before the scheduled time of your procedure, drink another bottle of clenpiq.
  • Drink an additional 5 cups (8 oz each) of water or clear liquids.
  • 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 prep, your stool should become a clear, yellow-tinged fluid. If the stool coming out is not a clear, yellow-tinged fluid, please drink an additional 32 ounces 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 colonoscopy 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 a 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.
