How often must pharmacy DEA registration be updated?

The requirement for pharmacies to update their DEA registration is based on federal regulations that mandate renewals every three years. This renewal process ensures that the DEA maintains up-to-date records regarding the registered entities that handle controlled substances, allowing for effective monitoring and compliance with regulations.

This three-year cycle helps the DEA keep track of active pharmacies and their authorized activities concerning controlled substance dispensing. It also serves as an opportunity for pharmacies to verify or update their registration information, which is critical for maintaining legal operation in the handling of controlled drug inventory.

The other options provide intervals that do not align with DEA regulations; thus, they would not be applicable for satisfying the requirements outlined in the law.
