Adverse Effects From Counterfeit Alprazolam Tablets

Abstract

the California Poison Control System-San Francisco division identified 8 patients who experienced adverse effects associated with the ingestion of counterfeit alprazolam tablets found to contain fentanyl and, in some cases, etizolam. The identification of these patients resulted in a coordinated response that included state and local public health departments, a toxicology laboratory, and media outlets, and resulted in an investigation by local law enforcement agencies.
