What is hydroxocobalamin?
Hydroxocobalamin is a form of vitamin B-12. It is used as an antidote to cyanide
poisoning. Hydroxocobalamin works by helping cells in the body convert cyanide to a form that
can be removed from the body through urination.
Hydroxocobalamin is used in an emergency to treat cyanide poisoning. This type of
poisoning can occur if you are exposed to smoke from a house or industrial fire, if you swallow
or breathe in cyanide, or if you get cyanide on your skin.
Hydroxocobalamin may also be used for purposes other than those listed in this
medication guide.
