How frequently should an inventory of controlled substances be taken?

Taking an inventory of controlled substances is a critical aspect of pharmacy practice, ensuring compliance with regulations and maintaining accurate records. According to the Drug Enforcement Administration (DEA), a pharmacy must take a complete and accurate inventory of all controlled substances on hand every two years.

This two-year requirement allows pharmacies to monitor their stock of controlled substances carefully, helping to prevent illegal diversion and ensuring that all controlled substances are accounted for. By adhering to this schedule, pharmacies maintain compliance with legal standards and contribute to the integrity of the controlled substances distribution and prescription systems.

While options suggesting annual, triennial, or quinquennial inventories do not align with the DEA's specific requirement, they may reflect other practices or regulations that are not as stringent in terms of the frequency of inventory checks for controlled substances. The two-year cycle strikes an important balance between sufficient oversight and practicality for pharmacies managing these substances.
