[Toxicity to rodenticides and its treatment]

A case is presented of exposure to a rodenticide which caused a severe disorder of hemostasis, including macroscopic hematuria, several months after the patient was exposed to it. Response to treatment with vitamin K and barbiturates came only after 70 days. The cause-and-effect relationship between exposure to the rodenticide and the disorder in hemostasis is based on the clinical course and on the late response to treatment.
