Introduction: Zinc phosphide is a rodenticide compound which converts to phosphide gas and leads to impairment of mitochondrial respiration. Previously, several cases of suicide attempt by ingestion of metal phosphide including aluminum and zinc phosphide have been reported. However, suicide attempt by injection of zinc phosphide has not been reported in the literature.
Case Presentation: In this paper, we report a suicide attempt by subcutaneous selfinjection of zinc phosphide in forearm in a18-year- old female. Allergic reactions, hives, angioedema and suffocation were present in our patient at the time of admission. Vital signs and laboratory tests all were in normal ranges. Supportive therapy was performed for the patient. The patient underwent supervision of a psychiatrist. Citalopram 20 mg and Valproate sodium 200 mg were prescribed for the patient.
Conclusions: Since, zinc phosphide poisoning has a high mortality rate, prompt resuscitation effort is crucial to improve survival. Supportive therapy is all we can do for patients. It seems that injection of zinc phosphide under the skin is not life-threatening.
