Colonoscopy with Miralax
For this preparation, you will need:
- One 238 gram bottle of Miralax (available over the counter without a prescription)
- Four Dulcolax tablets
- 64 oz of your favorite clear liquid (preferably Gatorade or Crystal Light,) – do not purchase a red colored liquid
Medication and Diet Instructions:
Seven days before the procedure:
If you take aspirin (and or aspirin containing products), Plavix, Eliquis or any other medication which may influence your ability to clot, please get specific instructions from your doctor about when or if you must stop these medications prior to your procedure.
Three days before the procedure:
- If you take Coumadin (warfarin) for a heart valve please speak to your prescribing cardiologist about alternatives prior to your procedure.
- If you take non-steroidal anti-inflammtories (NSAIDS; Advil, Motrin, Aleve), please discontinue three days prior to your exam. You may use Tylenol as an alternative if needed for pain.
- Avoid eating nuts, seeds, popcorn, grapes, green peas, beans and tomatoes. Fibers from these foods can clog the colonoscope.
On the day before the procedure:
You may have a regular breakfast. After breakfast, you will need to go on a clear liquid diet. You can drink clear liquids up to 2 hours prior to the appointment. Avoid juices with pulp such as orange or grapefruit juice. No dairy products, cream or soy. Coffee and tea are O.K. Examples of clear liquids include broth or bouillon, Jell-O, clear juices (white grape or apple), sports drinks such as Gatorade or PowerAde, sodas such as Sprite, 7-Up, or gingerale, lemonade, Popsicles, coffee or tea and of course, water. Avoid red or purple colored liquids. You may use sugar, honey or lemon. It is important that you drink as much fluid as you can throughout the day. It is also worthwhile to get a supply of aloe wet wipes and Desitin ointment to ward off a sore bottom.

Commonly asked Questions:
How do I know if my prep is adequate?
The stool should be watery in consistency. It does not have to be clear in color like water since digestive juices will continue to tint the stool yellow and small flecks of debris are not a problem as long as the stool is not muddy or thick. If there is any question, you can self administer a fleet enema prior to leaving home for the procedure..
What side effects may I expect?
Since the prep works by flooding the intestinal tract with fluid, abdominal bloating and cramping may occur, as well as some nausea and vomiting. This is usually temporary, and as the diarrhea develops, symptoms will gradually improve. Weakness can also occur, especially if you have not taken enough fluid with the prep, and can be remedied by increasing fluid intake (especially with sports drinks such as Gatorade or PowerAde).
Will the prep interfere with my other medications?
Medications taken at least an hour before beginning the prep should be adequately absorbed, but thereafter, they are likely to be washed away by the prep.
