Barium sulfate is used to help doctors examine the esophagus (tube that connects the mouth and stomach), stomach, and intestine using x-rays or computed tomography (CAT scan, CT scan; a type of body scan that uses a computer to put together x-ray images to create cross-sectional or three dimensional pictures of the inside of the body). Barium sulfate is in a class of medications called radiopaque contrast media. It works by coating the esophagus, stomach, or intestine with a material that is not absorbed into the body so that diseased or damaged areas can be clearly seen by x-ray examination or CT scan.
Barium sulfate comes as a powder to be mixed with water, a suspension (liquid), a paste, and a tablet. The powder and water mixture and the suspension may be taken by mouth or may be given as an enema (liquid that is instilled into the rectum), and the paste and tablet are taken by mouth. Barium sulfate is usually taken one or more times before an x-ray examination or CT scan.
