Cyanide is an ion with the formula of CN-, or a group with a formula of CN. It is a pseudohalogen, and forms a number of compounds, many of them are extremely toxic.

Cyanide compounds
Cyanide complexes
- Potassium ferrocyanide (potassium hexacyanoferrate (II))
- Potassium ferricyanide (potassium hexacyanoferrate (III))
- Sodium tricyanocuprate (I)
- Prussian blue
Other compounds containing the cyanide group
Cyanide toxicity
Cyanide compounds are potent blood agents, particularly the infamous potassium cyanide. However, there are a number of antidotes.
- Methylene blue, a general purpose antidote against blood agents, 50-100 ml of 1% solution intravenously. However, this only temporarily binds cyanide and borrows more time for a more permanent solution.
- Sodium thiosulfate, 250 mg/kg of 30% solution intravenously. This gradually binds cyanide into thiocyanate, which can be harmlessly purged from the body. This should be used after treatment with methylene blue, to thwart the cyanide permanently.
- Glucose, which has a similar, if weaker effect. Injecting it intravenously, or consuming sugar-rich food, is recommended before you start working with cyanides, to provide you with increased resistance for a time.
Note that cyanide poisoning is an exclusively acute condition with no chronic effects. It means, if you successfully thwart it, no long-term repercussions will follow. However, it is a very rapidly advancing condition, so in most cases there is no time to wait for medical attention. This is the reason why you should know the antidotes and how to use them yourself.
