Suicide attempts are frequent during adolescence. Intentional ingestion of rat poison is not well known in France. The complications of this are prolonged and may be serious.
Case report: An adolescent, 15 years old, with clinical hemorrhagic syndrome, had coagulation deficiency. Rat poison had been found in serum. The young girl recognized later that the ingestion of these toxins was intentional.
Conclusion: Suicide attempt with rat poison is exceptional, but we have to mention it when vitamin K-dependent factors failed without any other explication.
