Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive cesium poisoning.[2][3] For thallium it may be used in addition to gastric lavage, activated charcoal, forced diuresis, and hemodialysis.[4][5] It is given by mouth or nasogastric tube.[3][5] Prussian blue is also used in the urine to test for G6PD deficiency.[6]

Side effects may include constipation, low blood potassium, and stools that are dark.[2][4] With long-term use, sweat may turn blue.[4] It works by binding to and thus preventing the absorption of thallium and cesium from the intestines.[4]

Prussian blue was developed around 1706.[7] It is on the World Health Organization's List of Essential Medicines.[8] As of 2016, it is only approved for medical use in Germany, the United States, and Japan.[9][10][11] In the United States a course of treatment costs more than $200.[3] Access to medical-grade Prussian blue can be difficult in many areas of the world including the developed world.[12]

Medical uses

Prussian blue is used to treat thallium poisoning or radioactive cesium poisoning.[2][3][13] It may also be used for exposure to radioactive material until the underlying type is determined.[4]

Often it is given with mannitol or sorbitol to increase the speed it moves through the intestines.[5]

Prussian blue is also used to detect hemosiderin in urine to confirm a diagnosis of G6PD deficiency.[6]

Thallium poisoning

For thallium it may be used in addition to gastric lavage, forced diuresis, and hemodialysis.[4]

It is given until the amount of thallium in the urine drops to below 0.5 mg per day.[5]

Caesium poisoning

It is specifically only used for radioactive caesium poisoning when the caesium has entered the body either by swallowing or breathing it in.[5]

Dosage
