Hcmicidality and Psychosis Caused by an Over-the-Counter Performance-Enhancing Supplement Containing Dendrobium Extract and L-Dopa

摘要

We describe a 30-year-old man who was admitted to our hospital complaining of "being drugged with methamphetamine," along with psychotic and homicidal features, likely caused by four-month use of an over-the-counter (OTC) performance-enhancing supplement (PES) product containing dendrobium extract and L-dopa (L-3,4-dihydroxyphenylalanine). The patient denied a history of psychotic illness. He had abstained from anabolic steroids for four months and from alcohol for two months before admission. Treatment with oral olanzapine during the patient's 13-day hospitalization led to the resolution of his psychosis and homicidality. He was discharged to outpatient care with a primary diagnosis of substance (PES)-induced psychotic disorder (resolved).
