Neonatal death following clozapine self-poisoning in late pregnancy: An unusual case report

The report presents a fatal poisoning of a neonate occurring in the final stage of gestational life and evoked by his mother, who, while 9 months pregnant, took a toxic dose of clozapine aiming at committing suicide. She was also severely poisoned, but ultimately was saved.The woman had been taking the medication due to schizophrenia and depression prior to conception, and the discontinuation of the drug in the course of pregnancy increased the risk of the woman attempting suicide. In the course of comprehensive toxicological analysis based on the developed analytical procedure with the use of LC–APCI–MS, clozapine and its two metabolites, norclozapine and clozapine–N-oxide, were determined in postmortem blood, liver and kidney in concentrations explaining the death of the neonate.The interpretation of the above-described case is complex and – apart from toxicological aspects – also involves issues associated with psychiatry, pharmacotherapy in pregnancy and medicolegal problems.
