How frequently must a controlled substances inventory be taken?

The requirement to take a controlled substances inventory every two years aligns with federal regulations established under the Controlled Substances Act (CSA). The Drug Enforcement Administration (DEA) mandates that all registrants, including pharmacies, conduct an inventory of all controlled substances in their possession at least every two years to ensure compliance with legal standards and to monitor for potential abuse or diversion.

This regular inventory check serves several purposes, including maintaining accurate records, ensuring the proper handling and storage of medications, and preventing loss or theft. It helps pharmacists and pharmacy staff to remain vigilant about discrepancies that could indicate misuse.

While some organizations or settings might choose to conduct inventories more frequently, such as monthly for internal tracking and security purposes, the legal minimum set by the DEA is indeed every two years. Therefore, the selection of this frequency reflects adherence to federal guidelines and the importance of maintaining accountability in handling controlled substances.
