What is fentanyl buccal?
Fentanyl is a narcotic (opioid) pain medicine. Fentanyl buccal tablets are used to treat “breakthrough” cancer pain that is not controlled by other medicines. This medication is not for treating pain that is not cancer-related, such as general headaches or back pain. Fentanyl buccal may also be used for other purposes not listed in this medication guide.
