Which documents must be included in the records maintained for Schedule III-V substances?

The correct response emphasizes the necessity of maintaining comprehensive records for Schedule III-V substances, which includes invoices, receipts, and inventory records. This requirement is crucial for ensuring compliance with the regulations set forth by the Drug Enforcement Administration (DEA).

Invoices are important as they serve as proof of the procurement of controlled substances, detailing when and from whom the substances were acquired. Receipts are essential as they provide evidence of the sale or distribution of these substances, maintaining a clear trail of transactions. Inventory records are needed to track the quantities of substances on hand, helping to prevent misuse and ensure accurate reporting of inventory levels.

Together, these documents help in establishing accountability and transparency in the handling of controlled substances. They facilitate audits and inspections by regulatory bodies and serve to protect both the pharmacy and the public from potential discrepancies or unlawful practices related to controlled substances.
