What is fentanyl buccal (Onsolis)?
Fentanyl is a narcotic (opioid) pain medicine.
Fentanyl buccal is used to treat "breakthrough" cancer pain that is not controlled by other medicines. Fentanyl buccal is taken together with other non-fentanyl narcotic pain medicine that is used around the clock. 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 purposes not listed in this medication guide.
What are the possible side effects of fentanyl buccal (Onsolis)?

Stop using fentanyl and call your doctor at once if you have a serious side effect such as:
- weak or shallow breathing;
- pale skin, feeling light-headed or short of breath, rapid heart rate, trouble concentrating; or

Less serious side effects may include:

What is the most important information I should know about fentanyl buccal (Onsolis)?
Fentanyl buccal is available only under special programs called Fentora REMS or the FOCUS Program. You must be registered in the program and sign documents stating that you understand the risks and benefits of taking this medication.
Do not use fentanyl unless you are already being treated with a similar opioid pain medicine and your body is tolerant to it. Talk with your doctor if you are not sure you are opioid-tolerant.
Fentanyl buccal tablets are used to treat "breakthrough" cancer pain. This medication is not for treating pain that is not cancer-related, such as general headaches or back pain.
Do not use fentanyl buccal if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days.
Before using fentanyl buccal, tell your doctor if you have a breathing disorder, a head injury or brain tumor, seizures, mental illness, a heart rhythm disorder, low blood pressure, liver or kidney disease, or a history of drug or alcohol addiction.
Keep this medicine out of the reach of children or pets. The amount of fentanyl in each fentanyl buccal tablet can be fatal to a child or pet who accidentally sucks on or swallows it. Seek emergency medical attention if this happens.
Fentanyl may be habit-forming and should be used only by the person it was prescribed for. Never share fentanyl with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
