Prussian blue is used to treat radioactive cesium or thallium, or non-radioactive thallium poisoning. It works by combining with thallium and cesium in the intestines. The combination is then removed from the body through the stools. By removing the thallium or radiocesium, the medicine lessens damage to your body's organs and tissues.
