Off-label drugs are medications that are approved for one or more medical issues, but are prescribed by doctors for a different (not "officially" approved) issue. For example, a drug that is approved to treat high blood pressure may also be prescribed by a doctor to help with insomnia, even though the drug has not been specifically tested or approved for that use.
Off-label prescribing is common and can be a useful tool for doctors to treat patients with conditions that may not have a specific, approved treatment. There are many such off-label drugs being used to effectively treat cancer, if you can find an open-minded doctor willing to help you obtain a prescription.
