Off-label use

What is off-label use?

Off-label use refers to prescribing or using an approved medication or medical device for a purpose, dosage or patient population beyond what regulatory approval specifically covers.

This practice is generally legal and, in many circumstances, medically appropriate, since physicians frequently prescribe based on their own clinical judgment about a patient's specific circumstances rather than being strictly limited to approved indications alone.

It becomes genuinely relevant to a personal injury claim where this specific use itself was inappropriate, or where the manufacturer specifically promoted this use despite inadequate supporting safety evidence.

Understanding this distinction matters considerably to properly evaluating whether a claim connected to this type of use is actually viable.

When does this specific use become legally significant to a claim?

Several distinct circumstances can transform an otherwise legal practice into the basis for a viable claim.

• The physician's decision to prescribe this way fell below the applicable standard of care
• The manufacturer specifically and improperly promoted this use, despite the specific FDA restriction
• Inadequate warning existed regarding risks specific to this particular use
• The specific use itself was genuinely unforeseeable, which could affect a product claim differently
• Clinical evidence supporting this specific use was genuinely lacking at the relevant time

Why does manufacturer promotion of this practice matter so significantly?

Because manufacturers generally face specific restrictions on how they may promote their own products, and improperly encouraging this type of use despite inadequate supporting safety evidence can itself become a distinct failure to warn claim.

Internal manufacturer marketing materials and sales representative communications, obtained through discovery, frequently reveal whether this type of promotion actually occurred and what the company genuinely knew about the associated risks.

This is distinct from a physician's own independent clinical judgment to prescribe this way, which is generally treated quite differently under a medical malpractice analysis instead.

How does this issue actually affect a specific claim's analysis?

Where a physician's own independent clinical decision led to this type of use, the analysis generally centers on medical malpractice principles and the applicable standard of care for that decision.

Where manufacturer promotion of the practice was itself improper, the analysis may instead center more heavily on product liability and failure to warn theories.

These theories can, and frequently do, overlap within a single case where both the prescribing decision and the manufacturer's own conduct are genuinely at issue.

Common questions

Is this type of prescribing use always considered improper or illegal?

No. It is generally legal and often medically appropriate, based on a physician's own clinical judgment. The legal question is whether the specific decision or promotion involved fell below applicable standards.

Can I sue a manufacturer for promoting this specific type of use?

Potentially yes, particularly where the promotion was improper and inadequate warning existed regarding risks specific to that particular use, which can support a failure to warn theory.

Does the learned intermediary doctrine still apply in a case involving this specific issue?

Generally yes, the learned intermediary doctrine still applies, meaning the manufacturer's warning duty generally runs primarily to the prescribing physician.
