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 not listed in this medication guide.
In an emergency situation it may not be possible to tell your caregivers about your health conditions. Make sure any doctor caring for you afterward knows you have received Hydroxocobalamin.
