Dispensing Requirements — Federal Law

It must be issued for a legitimate medical purpose by an individual practitioner acting in the usual course of professional practice. A document that fails this test is not a prescription under the CSA, no matter how complete it looks.

The prescriber carries the primary responsibility, but the pharmacist who fills the prescription carries a corresponding responsibility under 21 CFR 1306.04(a). A pharmacist can be liable for filling a prescription the pharmacist knew or should have known was not legitimate.

A person who knowingly fills a purported prescription that was not issued in the usual course of professional treatment is subject to the penalties for violating the CSA. The order is treated as an unlawful distribution, not a prescription.

Only a pharmacist acting in the usual course of professional practice who is either registered individually or employed by a registered pharmacy or registered central fill pharmacy. The pharmacist's own professional judgment is part of the 'usual course' standard.

DEA has held that a pharmacist violates corresponding responsibility not only with actual knowledge but also through willful blindness, meaning deliberately ignoring obvious red flags. Filling while consciously avoiding the truth is treated like knowing it.

Common red flags include patients traveling long distances, paying cash, presenting the same 'cocktail' of drugs, requesting early refills, and a prescriber writing identical drugs, strengths, and quantities for many patients. Others include multiple patients at one address and prescriptions from many prescribers for one patient.
