Which of the following is a requirement for the storage of controlled substances?

The requirement that controlled substances must be stored separately from non-controlled substances is crucial for maintaining proper regulatory compliance and ensuring safety in pharmacies. This separation helps to prevent inadvertent access to controlled substances by unauthorized personnel and minimizes the risk of misuse or diversion.

Storing controlled substances separately also allows for easier inventory management and tracking, facilitating compliance with federal and state regulations that govern the handling of these substances. Proper segregation ensures that controlled substances are adequately monitored and accounted for, in line with the requirements set forth by the Drug Enforcement Administration (DEA) and state pharmacy boards.

The other choices present requirements or practices that do not align with standard regulations for the storage of controlled substances. For example, while access to storage areas is generally restricted, it is not solely limited to licensed pharmacists; appropriately trained and authorized personnel may also have access. Additionally, keeping controlled substances in their original packaging is good practice for identification and stability, but not a strict legal requirement. Lastly, sharing controlled substances between pharmacies is heavily regulated and typically not permitted without proper transfer protocols. Thus, the focus on separate storage of controlled substances stands out as a clear and essential requirement in pharmacy practice.
