What is a key requirement for a prescription of a controlled substance?

A key requirement for a prescription of a controlled substance is that the prescriber must include their Drug Enforcement Administration (DEA) number. This unique identifier is crucial for verifying that the prescriber is authorized to prescribe controlled substances and helps prevent drug abuse and illegal prescribing. The DEA number ensures a level of accountability, allowing pharmacies to confirm the legitimacy of prescriptions and the authority of the prescriber.

In the context of controlled substances, several regulatory frameworks emphasize the importance of prescriber information. While a prescriber's credentials, legible signatures, and even patient information might be necessary for various prescriptions, they lack the specific requirement tied to controlled substances like the prescriber’s DEA number does. This number must be written on all prescriptions for controlled substances to comply with federal and state laws, thereby ensuring safe and legal prescribing practices.
