If a drug that is non-controlled becomes a controlled substance, what action must be taken?

• A. Inventory control of that drug must be done on the date it becomes controlled
• B. Wait until next scheduled inventory
• C. Note in ledger but no physical count
• D. Notify the manufacturer

Answer: (A)

When a drug moves from non-controlled to controlled, you must establish an initial controlled-substance inventory on the date it becomes scheduled. This creates a precise starting point for accountability and aligns with regulatory requirements that controlled substances be tracked from the moment scheduling takes effect. Simply noting it in a ledger or waiting for the next inventory doesn’t establish that starting point, and notifying the manufacturer isn’t part of the facility’s required inventory action. So, you perform an inventory of that drug on the date it becomes controlled.
