When must controlled and non-controlled substances be disposed of?

The correct answer indicates that controlled and non-controlled substances must be disposed of when they are removed from inventory. This is crucial because proper disposal is part of ensuring the safe management of pharmaceuticals, particularly controlled substances, which can pose a risk of abuse and diversion. When substances are identified as expired, damaged, or otherwise unsuitable for use, it is important to remove them from active inventory to prevent accidental dispensing or misuse.

This practice is aligned with regulatory guidelines that dictate the importance of having a process for disposing of medications responsibly. Ensuring that these substances are disposed of immediately upon removal from inventory helps maintain compliance with legal and safety standards set forth by authorities such as the Drug Enforcement Administration (DEA) and state pharmacy boards.

While options like managing expiration dates or handling patient returns are relevant in specific contexts, they do not directly relate to the broader requirement of inventory management and timely disposal upon identification of unsuitability. Proper disposal protocols emphasize the importance of preventing any opportunity for these substances to be misused or mishandled, further reinforcing the importance of the correct answer concerning regulatory compliance in pharmacy practice.
