Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive caesium poisoning. [1] [2] For thallium it may be used in addition to gastric lavage, activated charcoal, forced diuresis, and hemodialysis. [3] [4] It is given by mouth or nasogastric tube.

There are two main methods of removing both radioactive and stable isotopes of thallium from humans. The first known was to use Prussian blue (potassium ferric hexacyanoferrate), which is a solid ion exchange material, and absorbs thallium.

Jan 31, 2025 · Prussian blue is a pill that can help remove radioactive cesium and thallium from people’s bodies. Prussian blue traps radioactive material in the intestines and removes it through bowel movements. You can only obtain Prussian blue through a doctor.

Prussian blue is a sequestering agent for certain heavy metal ions and a thallium poisoning antidote. Treatment with Prussian blue (or activated charcoal) interrupts the enterohepatic cycling of thallium, thus enhancing faecal elimination of the metal.

Thallium poisoning can be successfully treated with potassium ferric hexacyanoferrate (Prussian blue). Gastric lavage (within six hours of ingestion) and induced emesis may help prevent thallium absorption.

However, Prussian blue's safety profile is superior to that of other proposed therapies and it should be considered the drug of choice in acute thallium poisoning. Public health efforts should focus on greater restrictions on access to, and use of, thallium salts.
