Colonoscopy Commonly Asked Questions

Why choose a gastroenterologist?

Gastroenterologists are board-certified specialists who undergo extensive and rigorous training to gain expertise in endoscopic therapy (EGD, colonoscopy, ERCP, EUS). This typically requires at least three years of specialty fellowship training, which focuses specifically on performing diagnostic and therapeutic endoscopy on a daily basis. By the end of their training…

If you are using a prescription bowel prep, we have sent the prescription to your requested pharmacy. Occasionally, the pharmacy will put the prescription away if patient does not pick it up, but they still have the electronic prescription stored in your profile. If using Miralax this is an over the counter product and can be picked up in most stores.

If you feel very nauseous or if you have vomiting, then take a break for an hour. If symptoms improve, then restart at a slower pace. Refrigeration of the prep often makes it easier to drink.

Bloating, nausea, cramping, diarrhea. Potentially even vomiting. Typically, bloating and cramping begin to improve once you begin having bowel movements. If you feel very nauseous, then take a break for an hour and if symptoms improve, then restart at a slower pace. Refrigeration of the prep often makes it more palatable.

The prep will often begin working within 30 minutes, but it can take up to 3 hours or more to start working. You will need to remain close to a toilet.

If no bowel movement occurs within 5 hours, please contact our office for instructions.

You may apply a petroleum based product or diaper rash ointment to the rectal area if you experience discomfort from frequent stools.

Usually you may resume your normal diet unless otherwise instructed.

Yes. You can start it as early as 1pm.

Yes. This is not a problem.

Please call our office to discuss with a nurse.

Tylenol over the counter is okay.

No. Alcohol is a diuretic which can cause excessive and dangerous fluid losses and dehydration which can cause kidney failure. In addition, it can be a lethal combination with the sedative medications you will be given for the procedure.

Your stool should be translucent yellow, green, or clear. It may take up to a few hours to see an effect from the prep solution. You should complete your prep as instructed, even if it is apparently clear before you are finished with the prep instructions. This is because it usually takes several hours to get adequate bowel cleansing.

Medications swallowed at least one hour before starting the prep should be adequately absorbed. However, if you take oral medications during the bowel prep, they may not be absorbed completely.
