How often must a pharmacy conduct a controlled substances inventory?

Pharmacies are required to conduct an inventory of controlled substances every two years as mandated by federal regulations. This requirement helps to ensure that pharmacies maintain accurate records of their controlled substances, which is critical for compliance with drug enforcement laws and regulations. Conducting an inventory at this regular interval allows pharmacies to identify any discrepancies or issues with inventory management, such as theft, loss, or improper documentation. Ensuring proper oversight through biennial inventory helps to uphold the integrity of the controlled substances system and enhances patient safety by preventing the misuse of these drugs.

The other time frames mentioned, such as every year, every six months, or at the pharmacist's discretion, do not align with the established regulations governing inventory requirements for controlled substances, thus reaffirming that a biennial inventory is the correct practice.
