The Food and Drug Administration (FDA) regulates prescription drug marketing, not prescribing. However, off‐label use is common, often lacks supporting evidence, and may expose patients to unwarranted risk. We sought to determine physicians' knowledge of the FDA‐approved indications of commonly prescribed drugs, and to assess whether physicians' belief that an indication is FDA‐approved increases with level of evidence supporting such use.

Given the contradictory and unresolved expectations of major stakeholders, off‐label use remains problematic and requires a new policy paradigm that can successfully balance the need for innovation against the imperatives of evidence‐based practice and finite health‐care resources.

Experts’ Views on FDA Regulatory Standards for Drug and High-Risk Medical Devices: Implications for Patient Care

Experts identified advantages of expediting development and of FDA flexibility in applying its standards to new drugs and medical devices, but highlighted concerns that patients may not be adequately informed about the risks of shorter review times or about uncertainties in the evidence that result.

First Amendment Protection of Evidence-Based Promotion of Prescription Drugs: A Study of Published Clinical Evidence Supporting Off-Label Promotion in the USA

Some of the off-label uses alleged in FCA complaints investigated and settled by the federal government were supported by published clinical evidence; however, many of the alleged uses were unsupported by any clinical evidence and, thus, false and misleading.

Prescription Drug and Pharmaceutical Policy

This chapter is a primer for medical trainees that highlights the ways in which drugs are developed, approved, and paid for in the USA as well as the important differences between brand and generic medications.

Analyzing Patterns of Drug Use in Clinical Notes for Patient Safety

This work applied term extraction tools on the clinical notes of a million patients to compile a database of statistically significant patterns of drug use, and validated some of the usage patterns learned from the data against sources of known on-label and off-label use.

In many circumstances, an off-label medication may be in the patient's best interests; however, where there is a lower level of clinical justification, the informed consent of the patient and shared decision making of the patients is essential to optimize outcome.

Report of the Council on Scientific Affairs*: Unlabeled Indications of Food and Drug Administration-Approved Drugs

The AMA's Council on Scientific Affairs reviews and makes recommendations on four important subjects related to unlabeled uses: clinical significance and prescribing; coverage and reimbursement; dissemination of information by pharmaceutical manufacturers; and improving the Supplemental New-Drug Application (SNDA) process.

Off-label prescribing among office-based physicians.

Off-label medication use is common in outpatient care, and most occurs without scientific support, so efforts should be made to scrutinize underevaluated off-label prescribing that compromises patient safety or represents wasteful medication use.

‘Off-label’ drug use: an FDA regulatory term, not a negative implication of its medical use

The doctor's decision to inform the patient of the ‘off-label’ status of the prescription is not relevant to the physician's standard of care for an informed consent case, and doctors should not be branded with the additional duty of disclosing non-pertinent information, such as the FDA's medically irrelevant distinction, to their patients.

The prevalence of off-label drug use in routine clinical practice and the development of newer and more costly drugs for treatment of HIV and its medical complications argues for the articulation of an explicit national reimbursement policy for off- label uses of prescription drugs so that medically appropriate therapies will be available to those with insurance in a rational, consistent way.

Marked increases in COX-2 inhibitor use have occurred since their release, primarily among patients at low risk for adverse events from NSAIDs, demonstrating the challenge of limiting innovative therapies to the settings in which they are initially targeted and maximally beneficial.
