Which requirement applies to prescribing controlled substances?

• A. A DEA number must be included on the prescription
• B. No special requirement beyond the provider’s signature
• C. A separate hospital approval is always needed
• D. A DEA number is optional in emergencies

Answer: (A)

Authority to prescribe controlled substances hinges on the prescriber being registered with the DEA, and that registration number must appear on the prescription. The DEA number is a unique credential that verifies the prescriber is authorized to handle controlled substances and allows pharmacies to verify legitimacy and track dispensing for safety and regulatory purposes.

This requirement applies to all schedules of controlled substances and is not satisfied by a signature alone. It’s not contingent on a separate hospital approval. Even in emergencies, the prescription must bear the DEA number to be legally dispensed, reflecting ongoing need to confirm authority and prevent diversion.

So, the key rule is that a DEA number must be included on the prescription.
