Fentanyl is available as a skin patch, lozenge, pills, shots, a film that dissolves in your mouth, nasal spray, or by IV (intravenous).
Use fentanyl exactly as prescribed by your doctor. This is very important so that you do not get too much of the drug. If you get too much fentanyl in your system, you could have serious problems that can lead to death.
How It Works
Fentanyl acts upon specific receptors in your brain and spinal cord to decrease the feeling of pain and to reduce your emotional response to pain. The action of fentanyl is similar to other drugs in the morphine category (opioids).
Why It Is Used
Fentanyl is used to manage moderate to severe pain, usually in people who have chronic pain. It may also be used for breakthrough pain. Fentanyl is often used when your other pain medicines no longer work.
How Well It Works
For people with cancer who are already on opioid pain medicine such as morphine or oxycodone, fentanyl works well for treatment of cancer pain.1
Fentanyl has many side effects, including:
- Weakness and fatigue.
- Feelings of elation (euphoria).
- Dry mouth.
- Difficulty urinating.
- Difficulty breathing.
- Constipation, which may be severe.
- Skin reactions, such as irritation, itching, or hives.
Fentanyl can cause your body to expect this medicine daily (drug dependency). Dependency is not the same as addiction, which is a behavioral disorder marked by craving a drug.
Reasons not to use fentanyl
Fentanyl can cause serious or life-threatening respiratory problems (hypoventilation). For that reason it should not be used in:
- Cancer patients who have not been taking continuous opioid pain medicines.
- The management of pain that responds to other pain medicine.
- Doses greater than 25 mcg per hour at the beginning of opioid therapy.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
In some people, fentanyl impairs balance, coordination, or the ability to think. Do not drive or operate any type of equipment if you are taking fentanyl. If you have severe side effects, call your doctor, and stop taking this medicine.
Do not drink alcohol or use other drugs while you are taking fentanyl.
Fentanyl can interact with many other drugs. Make sure that your doctor is aware of all the medicines you are taking.
Fentanyl should be used during pregnancy only if the benefits to the mother outweigh the risks to the fetus. If you are or may be pregnant, talk with your doctor before using fentanyl. This drug can pass through your body in breast milk and should not be used if you are breast-feeding.
When you remove your fentanyl patch, dispose of it as your doctor tells you to.
Avoid the use of heat, such as a heating pad, electric blanket, hot tub, or sauna, while you are using a fentanyl patch. Heat can increase the amount of fentanyl released from the patch, which causes more risk of serious side effects.
