Precautions

Neodymium metal dust is a combustion and explosion hazard.

Neodymium compounds, like all rare earth metals, are of low to moderate
toxicity; however its toxicity has not been thoroughly investigated.
Neodymium dust and salts are very irritating to the eyes and mucous
membranes, and moderately irritating to skin. Breathing the dust can
cause lung embolisms, and accumulated exposure damages the liver.
Neodymium also acts as an anticoagulant, especially when given
intravenously.

Neodymium magnets have been tested for medical uses such as magnetic
braces and bone repair, but biocompatibility issues have prevented
widespread application.
