Prussian blue is also the treatment for thallium (Th) toxicity, via a similar mechanism.

Constipation is also commonly reported, and stools may be blue in color. The medication should be taken with food to enhance biliary secretion of Cs.

Although pregnancy category C, pregnant patients should likely still be treated as the benefits likely outweigh the risks.
