How frequently does the DEA require pharmacies to take inventory?

Pharmacies are required by the DEA to take an inventory of controlled substances every two years. This regulation is in place to ensure proper control and management of these drugs, which are subject to abuse and diversion. The biennial inventory helps to maintain accurate records of the quantities of controlled substances on hand, aiding in the prevention of misuse and ensuring compliance with federal and state laws.

Taking inventory more or less frequently than every two years could lead to either an excessive burden on pharmacy operations or insufficient oversight for controlled substances, which could result in discrepancies and potential regulatory issues. This requirement underscores the importance of regular audits within the pharmacy to ensure proper dispensing and storage of controlled medications.
