What is fentanyl transdermal (Duragesic, Duragesic-100, Duragesic-12, Duragesic-25, Duragesic-50, Duragesic-75)?

Fentanyl is a narcotic (opioid) pain medicine.

The fentanyl skin patch is used to treat moderate to severe chronic pain.

Fentanyl transdermal may also be used for other purposes not listed in this medication guide.

What are the possible side effects of a fentanyl transdermal skin patch?

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Remove the skin patch and call your doctor at once if you have any of these serious side effects:

• weak, shallow breathing;
• severe weakness, feeling light-headed or fainting;
• cold, clammy skin; or
• pale skin, easy bruising or bleeding.

Less serious side effects may include:

• nausea, vomiting, stomach pain, constipation, gas;
• dizziness, drowsiness, anxiety, sleep problems (insomnia);
• muscle stiffness, back pain;
• itching, blistering, redness, or swelling where the patch was worn; or
• increased sweating, urinating less than usual.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

MISUSE OF THIS MEDICATION CAN CAUSE HARMFUL OR FATAL SIDE EFFECTS.

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. Talk with your doctor if you are not sure you are opioid-tolerant.

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.

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.

Keep both used and unused fentanyl transdermal patches out of the reach of children or pets. The amount of fentanyl in a used skin patch could be fatal to a child or pet who accidentally sucks on or swallows the unit. Seek emergency medical attention if this happens.

Avoid drinking alcohol, or using other medicines that make you sleepy (such as cold medicine, other pain medication, muscle relaxers, and medicine for depression or anxiety). They can add to extreme drowsiness or breathing problems caused by fentanyl.

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.
