What must be done to Schedule IV substances in opened containers during an inventory?

For Schedule IV substances in opened containers during an inventory, estimating their count is the appropriate action. This is because federal regulations allow for estimated counts of certain controlled substances under specific conditions, particularly when they are in open containers. Many facilities utilize this approach to streamline the inventory process, focusing on practicality while maintaining compliance with regulatory standards.

In the case of opened containers, an exact count might not be feasible for various reasons, such as the inability to access the entire contents or the significant volume that may make counting impractical. Therefore, estimating allows for a reasonable approximation that satisfies regulatory requirements while acknowledging the practical limitations of inventory procedures.

This approach balances regulatory compliance with operational efficiency and reflects an understanding of the regulations governing controlled substances, which recognize that exact counts may not always be necessary under certain circumstances.
