After Having This Test Side Effects of This Medicine Category Diagnostic aid, radiopaque, gastrointestinal disorders Description Barium sulfate is a radiopaque agent. Radiopaque agents are used to help diagnose certain medical problems. This creates the needed distinction, or contrast, between one organ and other tissues. The contrast will help the doctor see any special conditions that may exist in that organ or part of the body.
Barium sulfate is taken by mouth or given rectally by enema.
The dose of barium sulfate will be different for different patients and depends on the type of test. The strength of the suspension and tablet is determined by how much barium they contain. Barium sulfate is to be used only by or under the direct supervision of a doctor. In deciding to use a diagnostic test, any risks of the test must be weighed against the good it will do. This is a decision you and your doctor will make.
