Appropriate bowel cleansing is one of the most important steps in performing a successful and accurate colonoscopy. Please read this sheet in advance of your procedure and follow these instructions carefully.

One week prior to procedure:

• Purchase the following items at your local pharmacy:
  • Three 10-ounce (296 mL) bottles of Magnesium Citrate and two Dulcolax tablets
  • Consider purchasing a large bottle (64 ounces) of a sports drink (but not red/purple) to stay hydrated (I recommend Coco5 or something natural without sucralose)
• Avoid red/purple foods, nuts, seeds, popcorn, grapes, peas, beans and tomatoes since these foods may interfere with preparation.
• If you take blood thinners such as Aspirin (or Aspirin containing products), Plavix (Clopidogrel), Effient (Prasugrel), Coumadin (Warfarin), Pradaxa (Dabigatran), Xarelto (Rivaroxaban), Eliquis (Apixaban), or any other blood thinners please inform us in advance so that these medicines can be adjusted appropriately.
• If you are a diabetic and take insulin or other medications to lower your blood sugar, please inform us in advance so that these medicines can be adjusted appropriately.
• Stop any anti-inflammatory medicines (Aleve, Motrin, Advil, Ibuprofen, Naproxen). You can take Tylenol if needed for pain.
• Stop taking iron supplements or vitamins containing iron.

On the day before the procedure:

• You may have a light breakfast.
• You will need to be on a “clear/thin” liquid diet for the rest of the day. Examples of clear/thin liquids include water, broth, Jell-o, juices, sports drinks, sodas, ginger ale, lemonade, popsicles, coffee/tea (without milk).
• Avoid red- or purple-colored liquids, juices with pulp, dairy products.
• It is important to stay hydrated and drink as much fluid as you can throughout the day!

The preparation:

• If your procedure is in the morning:
  • Drink the first bottle of Magnesium Citrate at 6 pm the night before your procedure along with the two Dulcolax tablets.
  • Drink the second bottle of Magnesium Citrate at 8 pm the night before your procedure.
  • Drink the third bottle of Magnesium Citrate at 10 pm the night before your procedure.
  • Drink plenty of fluids (non-red sports drink or water) to help the cleansing process and to stay hydrated.
• If your procedure is in the afternoon:
  • Drink the first bottle of Magnesium Citrate plus the two Dulcolax tablets at 8 pm the night before your procedure.
  • Drink the second bottle of Magnesium Citrate at 10 pm the night before your procedure.
  • Drink the third bottle of Magnesium Citrate at 6 am the morning of your procedure.
