A 43-year-old male psychiatric outpatient died within hours of ingesting as
much as 600 mg of olanzapine, a newer antipsychotic agent related to cloza
pine. Analysis of postmortem blood and urine by gas chromatography with nit
rogen-selective detection yielded olanzapine concentrations of 1238 and 698
7 mu g/L, respectively greatly in excess of levels expected following thera
peutic administration of the drug. Based on the toxicology findings, the de
cedent's known history of suicide attempts, and the circumstances surroundi
ng the death, this case was ruled a suicide by olanzapine overdosage.
