What Happened
In August 2024, Tuan Alex Nguyen, M.D., of Oklahoma City, paid $165,000 to settle civil penalty claims alleging violations of the Controlled Substances Act. The United States alleged that from November 2022 to September 2023, Dr. Nguyen issued prescriptions in Oklahoma for Schedule III controlled substances without the required certificate of registration from the Oklahoma Bureau of Narcotics. The Act requires a prescriber to be authorized to prescribe the substance in the jurisdiction where he or she is licensed. Dr. Nguyen did not admit liability, and the government made no concessions about the legitimacy of its claims. The DEA Office of Diversion Control investigated.
