Off‐Label Use of Drugs and Medical Devices: A Review of Policy Implications

“Off‐label use” occurs when the use of a medication or device deviates from what is mentioned in its US Food and Drug Administration (FDA) product label. Off‐label use is common, legal, and an important source of innovation; however, it can be costly, and strong evidence of the efficacy and safety of such use may be lacking. 1 Given the contradictory and unresolved expectations of major stakeholders, off‐label use remains problematic. It 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.
