What is the correct procedure when a person unknown to the pharmacist wishes to pick up a controlled substance?

When a person unknown to the pharmacist wishes to pick up a controlled substance, the correct procedure involves requesting valid identification, particularly for controlled substances classified as Schedule II (CII) or Schedule III (CIII). This requirement is crucial for ensuring the security and integrity of controlled substances, which are subject to strict regulations due to their potential for abuse and dependence.

By requesting valid identification, the pharmacist can verify that the individual is authorized to receive the medication, which is essential for preventing diversion and ensuring patient safety. This step not only complies with legal requirements but also helps maintain the pharmacy's responsibility in handling controlled substances.

In this context, relying solely on the prescribing physician for verification may not be practical or efficient, as it could delay the process unnecessarily. Similarly, asking the person to return with a known representative does not effectively address the immediate concern of verifying the individual's identity and authorization. Dispensing the medication without question would violate regulations and potentially compromise patient safety and legal compliance. Therefore, requesting valid identification stands out as the appropriate and responsible course of action.
