On DEA labels for controlled substances, which two items must appear?

• A. A capital C followed by a roman numeral identifying the schedule.
• B. A capital D followed by a numeric code identifying the drug.
• C. A barcode and expiration date.
• D. A chemical name and lot number.

Answer: (A)

The key idea is to clearly indicate that a substance is controlled and what schedule it falls under. On DEA-labeled containers, this is shown by a capital C followed by the Roman numeral that designates the schedule (for example, C-II or C-III). This pairing tells anyone handling the drug both that it’s regulated and how tightly it must be controlled, guiding secure storage, dispensing limits, and precise recordkeeping. Other details like barcodes, expiration dates, or lot numbers may appear for inventory or tracking, but they are not the required indicators of controlled-status and schedule.
