Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive cesium 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.[2][4] Prussian blue is also used in the urine to test for G6PD deficiency.[5]
Side effects may include constipation, low blood potassium, and stools that are dark.[1][3] With long term use, sweat may turn blue.[3] It works by binding to and thus preventing the absorption of thallium and cesium from the intestines.[3]
Prussian blue was developed around 1706.[6] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[7] As of 2016 it is only approved for medical use in Germany and the United States.[8][9] In the United States a course of treatment costs more than 200 USD.[2] Access can be difficult in many areas of the world including the developed world.[10]
Medical uses
Prussian blue is used to treat thallium poisoning or radioactive cesium poisoning.[1][2] It may also be used for exposure to radioactive material until the underlying type is determined.[3]
Often it is given with mannitol or sorbital to increase the speed it moves through the intestines.[4]
Prussian Blue is also used to detect hemosiderin in urine to confirm a diagnosis of G6PD deficiency.[5]
Thallium poisoning
For thallium it may be used in addition to gastric lavage, forced diuresis, and hemodialysis.[3]
It is given until the amount of thallium in the urine drops to below 0.5 mg per day.[4]
Cesium poisoning
It is specifically only used for radioactive cesium poisoning when the cesium has entered the body either by swallowing or breathing it in.[4]
