After dispensing an emergency Schedule II drug, the pharmacist must contact which entity if a written prescription is not received within the stipulated time?

In Massachusetts, when a pharmacist dispenses an emergency Schedule II drug, they are required to receive a written prescription from the prescriber within a specified time frame, typically within 7 days. If the pharmacist does not receive the written prescription within this period, they must contact several relevant entities to ensure compliance with regulatory requirements.

The correct answer indicates that the pharmacist must inform the Commissioner of the Massachusetts Department of Public Health, the DEA Office, and the U.S. Department of Justice. Each of these entities plays a role in regulating and overseeing the prescribing and dispensing of controlled substances. Notifying them helps to ensure that both state and federal laws are upheld, acknowledges potential compliance issues, and demonstrates the pharmacist's commitment to maintaining proper standards in the dispensing of controlled substances.

By contacting these agencies, the pharmacist not only fulfills their legal obligation but also protects themselves and their practice from potential legal repercussions that may arise from failing to receive the required documentation for the emergency dispensing of Schedule II drugs.
