Oxidizes hemoglobin to methemoglobin, which has high affinity for cyanide, forming cyanmethemoglobin and freeing cytochrome oxidase. Combined with sodium thiosulfate.
Creates controlled methemoglobinemia — dangerous if overdosed. Monitor methemoglobin levels. Do not use in smoke inhalation (already elevated carboxyhemoglobin).
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.
