What happens if a DEA registration is cancelled due to revocation or other reasons?

When a DEA registration is cancelled due to revocation or other reasons, it means that the practitioner is no longer legally allowed to handle controlled substances. This cancellation affects the authority to issue prescriptions for these substances, which includes any refills.

Once a DEA registration is cancelled, no refills are permissible. The pharmacy and the practitioners involved must adhere to this regulation to ensure compliance with federal drug laws and to safeguard against potential misuse or illegal distribution of controlled substances. As a result, the cancellation means that any previously authorized refills are no longer valid, necessitating that patients obtain a new prescription under a valid DEA registration if they still require their medication.

Thus, the accurate response reflects the legal implications of a cancelled DEA registration on the authority to prescribe and dispense controlled substances.
