The Law and Practice of Off-Label Prescribing and Physician Promotion.

Prescription of medications for off-label indications is an increasingly common practice; recent events highlight such prescribing as one of the cornerstones of evolving clinical treatment. Clinicians are afforded substantial deference in prescribing practices and other treatments falling within the realm of the actual practice of medicine, including prescribing for off-label indications. Yet clinicians are not necessarily free to promote a medication for the same off-label indication they may have just prescribed for a patient. While trends in jurisprudence appear to be favoring clinicians' freedom to promote prescription medication for any use, in a majority of jurisdictions, the U.S. government can still bring considerable weight to bear on clinicians promoting off-label uses of prescription medications. We review the relevant laws and regulations pertaining to off-label prescription and promotion, as well as the possible legal consequences. The regulations pertaining to physician and pharmaceutical manufacturers regarding off-label drug use are complex. Suggestions are provided to help physicians better navigate the medical-legal landscape when prescribing or promoting medications for off-label use. Physician mindfulness to pertinent legal precedents will allow them to prescribe and promote medications with a higher level of critical reasoning to optimize care and reduce risk.
