When receiving Schedule IV controlled substances, the pharmacy technician should check the drugs against the:

The narcotic inventory is a record of controlled substances currently held by the pharmacy. While it is important for tracking medications, it does not provide a direct comparison to the recent shipment, making it less relevant when verifying received Schedule IV drugs. The inventory reflects what is present rather than what has been ordered or received.

A formulary is a list of approved medications that a pharmacy can dispense, often including guidelines for therapy. However, it does not serve as a verification tool for received shipments. The formulary does not provide specific details regarding quantities or orders, making it inadequate for confirming the receipt of Schedule IV substances.

DEA Form 222 is specifically used for ordering Schedule I and II controlled substances, not Schedule IV. Thus, it is not applicable in this context. Checking against this form would not provide the necessary information regarding the receipt of Schedule IV drugs, as it is not part of the ordering process for these substances.
