What Does “Off-Label” Mean in Medicine?

What Does “Off-Label” Mean?

When people hear the phrase “off-label use of medication”, it can sound confusing or even concerning. In simple terms, “off-label” means that a doctor prescribes a medication for a use that is not included in the official FDA approval of that medication. This does not mean the use is unsafe or experimental. In fact, off-label prescribing is often a vital and common part of medical care in the U.S.

The FDA’s role includes approval of the types of conditions that a drug can treat which corresponds to the advertising that the pharmaceutical company provides. However, the FDA does not review every possible medical benefit of a drug, every related medical condition, or every piece of new research. That is where medical providers come in. Doctors may consider scientific studies, drug class similarities, mechanisms of action (this is explained further below), and clinical experience when deciding whether a medication may help beyond its original approval.

Why Off-Label Prescribing Happens

There are several reasons why a provider may recommend an off-label medication use:

  1. Drug Class Profiles
    If one medication in a class is FDA-approved for a condition, others in the same class may also work. For example, sertraline (Zoloft) is approved for social anxiety disorder, so it is reasonable for providers to also consider other SSRIs like fluoxetine (Prozac) for the same condition.
  2. Research Evidence
    Sometimes research supports an off-label use. For instance, bupropion (Wellbutrin) is not FDA-approved for ADHD, but some studies suggest it may help certain adults. Similarly, some providers may use second-generation antipsychotics (SGAs) off-label as adjuncts in treating PTSD, based on limited scientific research.
  3. Mechanism of Action
    A medication may logically help with another condition based on how it works in the body. Propranolol, a blood pressure medication, blocks the effects of adrenaline and may be prescribed off-label for panic attacks in some cases, based on how it works in the body. Another example is prazosin, also a blood pressure drug, which has been used to help with PTSD-related nightmares.
  4. Clinical Experience and Case Reports
    Sometimes providers learn from each other. For example, some providers may use bupropion off-label to help with sexual side effects caused by SSRIs, based on shared clinical experiences.

Common Examples of Off-Label Uses

Here are a few examples you may have heard of:

  • Gabapentin off-label uses: While approved for seizures and nerve pain, it is often prescribed off-label for anxiety, insomnia, and hot flashes.
  • Naltrexone off-label uses: Beyond its FDA approval for alcohol and opioid dependence, lower doses are sometimes prescribed off-label for chronic pain or autoimmune conditions.
  • Metformin off-label uses: Originally used for diabetes, it may also be prescribed off-label for polycystic ovary syndrome (PCOS).

Is Off-Label Use Appropriate?

Off-label use may be appropriate when overseen by an experienced prescriber. Off-label prescribing is not about taking unnecessary risks. It involves applying medical expertise, clinical research, and an understanding of patient needs to determine the most suitable treatment.

Final Thoughts

Off-label prescribing is one reason medicine is often described as an art based on science. By using research, class knowledge, and clinical experience, providers may help patients access treatments even when those treatments go beyond the FDA’s marketing approval.

If you have questions about your medications, including whether you are taking them for an off-label use, talk openly with your provider. Understanding why your medication was chosen can help you feel confident in your treatment plan.

Medications should only be taken as prescribed by a licensed provider. Off-label use may be appropriate in certain cases, but it should always be discussed with a qualified healthcare professional. Availability of specific treatments may vary by location and insurance coverage. Please consult your provider to understand what options are appropriate and accessible for you.
