What is fentanyl?
Fentanyl is a narcotic (opioid) pain medicine.
The fentanyl skin patch is used to treat moderate to severe chronic pain.
Fentanyl transdermal may be used for other purposes not listed in this medication guide.
Do not use this medication unless you are already being treated with a similar opioid (narcotic) pain medicine and your body is tolerant to it. Opioid medicines include morphine (Kadian, MS Contin, Oramorph, and others), oxycodone (Oxycontin), and hydromorphone (Dilaudid). Talk with your doctor if you are not sure you are opioid-tolerant.
Before using fentanyl, tell your doctor if you are allergic to fentanyl or any other medications, or if you have:
- a breathing disorder such as chronic obstructive pulmonary disease (COPD);
- a history of head injury or brain tumor;
- a heart rhythm disorder;
- liver disease; or
- kidney disease.
If you have any of these conditions, you may need a dose adjustment or special tests to safely use this medication.
FDA pregnancy category C. This medication may be harmful to an unborn baby, and could cause addiction or withdrawal symptoms in a newborn. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
Fentanyl may also cause addiction and withdrawal symptoms in a nursing infant. Do not use fentanyl transdermal without telling your doctor if you are breast-feeding a baby.
Older adults may be more likely to have side effects from this medicine.
Fentanyl may be habit-forming and should be used only by the person it was prescribed for. This medication should never be shared with another person, especially someone who has a history of drug abuse or addiction. Store the medication in a secure place where others cannot get to it.
The fentanyl transdermal patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.
This medication is for use only on the skin. Avoid touching the sticky side of a skin patch with your fingers. Do not allow the medicine to come into contact with your eyes, nose, mouth, or lips. If it does, rinse with water. Do not use soap or other chemicals.
Fentanyl can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Avoid drinking alcohol, which can increase dizziness or drowsiness.
Tell your doctor if you regularly use other medicines that make you sleepy (such as cold medicine, other pain medicine, muscle relaxers, and medicine for depression or anxiety). They can add to extreme drowsiness or breathing problems caused by fentanyl.
Do not expose the skin patch to heat while you are wearing it. This includes a hot tub, heating pad, sauna, or heated water bed. Heat can increase the amount of drug you absorb through your skin and may cause harmful effects.

Seek emergency medical attention if you think you have used too much of this medicine or if anyone has accidentally swallowed it. A fentanyl overdose can be fatal. Overdose symptoms may include slow breathing, extreme weakness or dizziness, pinpoint pupils, cold and clammy skin, or fainting.
Since fentanyl transdermal is used as needed, you may not be on a dosing schedule. If you are using the skin patches regularly, apply the missed patch as soon as you remember. Continue wearing the patch for up to 72 hours and then apply a new one if needed for pain. Do not wear extra patches to make up a missed dose.
