Preparing for your Colonoscopy: NULYTELY

The day before your colonoscopy:

DRINK CLEAR LIQUIDS ONLY.

Clear liquid is any liquid that you can see through, and includes:

  • Water, clear broth or bouillon, black coffee, or black tea (you may use sweeteners). DO NOT use or drink milk products.
  • Gatorade, Powerade, Vitamin Water, or Pedialyte that is clear, yellow, orange, or green. Electrolyte drinks are recommended to help you stay hydrated.
  • Lemonade, limeade, ginger ale, and clear sodas. DO NOT drink cola or root beer.
  • Apple juice, white grape juice, white cranberry juice.
  • Jell-O and popsicles are allowed if they are yellow, green, or orange colored.

Drink at least eight glasses of water or clear liquids. It is important to drink fluids the day before the procedure to keep you hydrated. The more you drink, the better you will feel.

Preparation timeline:

  • In the morning, add water up to the fill line of your Nulytely bottle.
  • Add the flavor packet that came with your bottle, or other powdered drink mix (such as Crystal Light). Use ONLY flavors that are yellow, orange, or green in color – DO NOT use flavors that are red, blue, or purple.
  • Stir/shake until the contents are completely dissolved. Chill the mixture if desired. You will drink this later in the day.
  • At 1 p.m. take two Dulcolax tablets with eight ounces of water.
  • At 3 p.m. take the remaining two Dulcolax tablets with eight ounces of water.
  • At 5 p.m. begin drinking the Nulytely solution. Drink one glass every 10 to 15 minutes to finish HALF the bottle within two to three hours. Using a straw will help make drinking the solution easier.
  • Refrigerate the remaining half of the mixture, you will drink this in the morning.

Please note that everyone reacts to laxatives differently. You may feel bloated, nauseated, or have stomach cramping while drinking the solution. This is temporary and will improve once you start having bowel movements. If you feel ill, stop drinking for 30 minutes and then resume drinking at a slower rate. Walking around between drinking each glass can help with bloating. Bowel movements usually start within two hours of starting to drink the liquids but may take longer.

The day of your colonoscopy:

  • Four hours prior to your procedure time, shake the remaining solution and finish drinking it within one hour.

  • You may have clear liquids (NO broth) up until three hours before your procedure time.
  • Three hours prior to your procedure time, you may take the following medications with a small sip of water:
    • Daily narcotic
    • Anti-anxiety
    • Blood pressure/cardiac medication
    • Seizure medication
    • Asthma inhalers
    • Thyroid medication

After taking your medications, nothing by mouth, EVEN WATER, THREE hours before your procedure time or else your procedure WILL be cancelled!
