How often must a pharmacy conduct an inventory of controlled substances?

The correct answer is that a pharmacy must conduct an inventory of controlled substances biennially, or every two years. This requirement is set by the Drug Enforcement Administration (DEA) as part of the regulations governing the handling of controlled substances to ensure proper accountability and tracking. Conducting an inventory biennially allows pharmacies to maintain an accurate record of their controlled substance stock, which is essential for regulatory compliance and helps prevent diversion or misuse.

Pharmacies have the option to conduct more frequent inventories if they wish to maintain tighter controls, but the regulatory standard specifically mandates this biennial schedule. Regular inventories serve the dual purpose of safeguarding public health and ensuring that pharmacies are in compliance with federal laws governing controlled medications.
