We describe a case of delirium due to olanzapine overdose. After ingestion of 280 mg of olanzapine, a 19-year-old schizophrenic patient developed a delirium (ICD-10: F 05.0) with consciousness disturbance, disorientation in time, space, and situation, acoustic and visual hallucinations, and agitation. The symptoms lasted for approximately 36 h. ⋯ There were no abnormalities in ECG, EEG, or routine blood tests. Approximately 36 h after the intoxication, the patient recovered fully. Until now, there have been no reports of delirium from this cause.
