How can you prepare for virtual colonoscopy?

ANSWER

You may have to change what you eat for a few days and take medicine to clean out your colon.

You’ll need to drink a special contrast liquid before the test.

Make sure your doctor knows about all of the medicine you take. That includes drugs you can get without a prescription, like vitamins, supplements, and herbs. She may ask you to stop some of these for a short time before the test.

Tell your doctor if you’ve had past reactions to the contrast liquid used during X-rays.

Don’t get this test if you’re pregnant.
