Barium sulfate is a medicine used in diagnostic testing. It is a radiopaque agent, which means it offers a contrast between organ tissues during an X-ray. The Mayo Clinic, in an article about “Barium Sulfate,” states, “The contrast will help the doctor see any special conditions that may exist in that organ or part of the body.” Barium sulfate is given by mouth in the form or tablets or liquids or as an enema. Once the testing is over, there are a few things you can do to cleanse the barium sulfate out of your body.

Things You'll Need

Drink plenty of fluids. The National Institute of Health, in its article “Barium Sulfate,” suggests to drink water and other fluids once testing has been completed.

Follow doctors’ orders. Listen carefully as your doctor or medical staff personnel tells you when, what, and how much to drink and eat following the test. According to the National Institute of Health, “You will be given specific directions to follow before and after your test.” Make certain you understand what you need to do. Because barium sulfate is given in various forms, in various doses, and by mouth or rectum, there are no guidelines that suit all people.

Use a laxative. Buy an over-the-counter laxative. Using a laxative is often a part of follow-up care after the use of barium sulfate, reports the National Institute of Health. But each situation is different, so only use a laxative if your doctor tell you to.
