Cyanide Toxicity

Cyanide's primary mechanism of harm is blocking oxygen delivery to the mitochondria, destroying the mitochondrial complex responsible for cellular energy production. The antidote to cyanide poisoning in emergency medicine is methylene blue, which bypasses mitochondrial damage and restores oxygen supply. People with impaired detoxification genes cannot adequately clear even small cyanide loads from cyanocobalamin, leading to gradual accumulation. Cumulative exposure from multiple cyanocobalamin sources can collectively deliver a meaningful total cyanide burden.
