Thorough cleansing of the bowel is mandatory. Instructions for doing so will be given by the health care provider. This will include using enemas, abstaining from all solid foods 2 or 3 days before the test, and taking laxatives.
To avoid dehydration, drink plenty of clear liquids (such as juices and broths). Unless otherwise instructed, continue taking any regularly-prescribed medication. Discontinue taking iron preparations a few weeks before the test, unless otherwise instructed by the health care provider (iron residues produce a dark black stool, which inhibits the view).
Complete emptying of the colon before the examination requires enemas or other purgatives. These must be repeated until no solid matter remains. An intravenous infusion and an injection will be given to administer a pain reliever and a sedative during the procedure.
People with valvular heart disease may receive antibiotics before and after the test to prevent infection. Outpatients must plan to have someone take them home after the test, as they will be woozy and unable to drive.
