Bowel preparation before a colonoscopy is extremely important. Good preparation allows a physician to thoroughly examine a colon. The bowels need to be completely and carefully cleaned so that the doctor can easily discover any potential problems. Polyps or other abnormalities may be harder to notice if the bowels aren’t prepped and emptied properly prior to the procedure.  You should consult the gastroenterologist that is performing your procedure for you about the details of your bowel preparation (solution, specific instructions) to ensure it is done correctly to allow for a better prep rather than relying on general instructions.  Do not discontinue any medications prior to your procedure without speaking with your doctor. Procedural preparations also change and evolve with time, so it is important to understand what preparation, solution, and instructions your doctor recommends now for the best preparation for your procedure.



  1. Start a liquid diet after breakfast (water, clear fruit juices, soda, coffee or tea, broth)
  2. Beginning at 6 pm, take one bottle of magnesium citrate, and at 10 pm, take a second bottle of magnesium citrate. Do not take magnesium citrate if you have a history of kidney disease.
  3. If you can not take the magnesium citrate secondary to kidney disease or any other reason, please drink 1 glass of colyte (8 ounces) every 10 minutes until finished with half of the container (2 liters) starting at 6 pm.
  4. Do not eat, drink, smoke, or chew gum except for necessary medication with a sip of water 12 hours prior to your capsule endoscopy. Iron pills should not be taken for 3 days prior to the examination.

  1. Please arrive at the office wearing loose fitting, two piece clothing. Preferably, wear an upper garment made of a thin, natural fiber such as a T-shirt that is long enough to reach a hip level and will not ride up above the belt.
  2. Do not take your regular medications. You will be able to take them 3 hours after swallowing the capsule.
  3. The sensor belt and recording device will be attached to our waistline over your belly button and should remain there.
  4. You will then swallow the small bowel capsule.


(Contact your doctor’s office immediately if you suffer from any abdominal pain, nausea, or vomiting during the procedure)

  1. Do not eat or drink for at least 2 hours.
  2. After 4 hours, you may have a light lunch and continue drinking clear liquids throughout the day.
  3. Please be sure the sensor belt is tight at the waist.
  4. Check the blue flashing PillCam recorder every 15 minutes to be sure it is blinking twice per second. If it stops blinking or changes color, note the time and contact your doctor.
  5. Do not disconnect the equipment at any time. You should not be near any source of powerful electromagnetic fields such as one created near an MRI device.
  6. Avoid any strenuous physical activity, including bending over during the test.
  7. Return to the doctors office at the scheduled time to have the equipment removed. If you were instructed to remove the equipment by yourself , do the following.
    • Remove the sensor belt and the PillCam record and keep them in a safe place
    • Return all the equipment to your doctor’s office as soon as possible. Handle the PillCam recorder and other equipment carefully without exposing them to shock vibration or direct sunlight.
  8. If you are not sure that the capsule has passed out of your body and you develop unexplained nausea, abdominal pain, or vomiting, contact your doctor for evaluation.
  9. Undergoing an MRI while the PillCam capsule is inside your body may result in damage to your intestinal tract or abdominal cavity. If you are not certain the capsule is out of your body, contact your physician for evaluation and possible abdominal x-ray before undergoing an MRI examination.

If you have any questions about these instructions or the small bowel capsule procedure, please call our offices at 212-427-8761 or contact your gastroenterologist.
