The United States Food & Drug Administration (FDA) is responsible for regulating both prescription and non-prescription medications. One of their roles in regulation is to ensure that medications are safe and effective. This is done through the FDA approval process.
This means the medication is used in a way that is not stated in the FDA labeling. Medications may be used off-label for several reasons such as:
Off-label use of medications is common. Although common, many patients may not know that a medication is prescribed off-label. So why are medications used off-label?
One reason may be that the FDA approval process is expensive and time-consuming. If the company would like to add an indication to a medication, an additional application is required. For this reason, a medication may still be helpful for off-label use even if it is not approved by the FDA. Off-label use of medications can be particularly useful for patients who have tried all other medications for a disease. Another reason a medication may be prescribed off-label is because there might not be an approved drug to treat a disease. One example is cancer medication. Often a cancer medication may be approved to treat one type of cancer, but is used off-label to treat other types of cancers. Although a medication is not approved for a condition, it may have been studied for its benefits in that condition.1,2
Once a medication is approved for one use, doctors can decide whether it is right for other uses. Several factors are considered when a health care provider decides to prescribe a medication. This includes deciding whether the medication is safe and effective for a specific patient.2,3
In most cases, taking a medication for off-label use is safe. Drug companies are required to prove that a medication is safe for people to use. They just don’t need to prove the drug works for treating an off-label condition. Sometimes a medication could help with symptoms of conditions that it was not approved for. There are many off-label uses that most doctors agree are safe and effective.4
