Hydroxocobalamin, a precursor of vitamin B12, has a history of use in the prehospital setting in France for cyanide poisoning, particularly that associated with smoke inhalation. Because cyanide poisoning by ingestion is less common than smoke inhalation-associated cyanide poisoning, less information is available on prehospital use of hydroxocobalamin to treat cyanide poisoning by ingestion. This report describes a case of prehospital use of hydroxocobalamin for poisoning by ingestion of cyanide. The case supports the efficacy of hydroxocobalamin for acute cyanide poisoning caused by ingestion of a cyanide salt. No adverse events attributed to hydroxocobalamin were observed.
