Radiogardase is given to people with known or suspected exposure to radioactive cesium-137 or radioactive or non-radioactive thallium. Radiogardase binds with radioactive cesium-137 or radioactive or non-radioactive thallium to help them pass out of the body faster. Radiogardase does not treat the complications of radiation exposure.

General Precautions with Regardase:

• Radiogardase may cause constipation. A fiber based laxative and/or high fiber diet is recommended during treatment. 
• Cesium-137 passes out of the body in urine and stools. You should take safety measures to make sure others are not exposed to your urine, stools, or blood. 
• Radiogardase may make your stool blue-colored. 
• Radiogardase may turn the mouth and teeth blue in people who cannot swallow capsules, when the capsules are opened and mixed with food and eaten.
