What is the most important information I should know about a fentanyl transdermal skin patch?

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.

What is fentanyl transdermal?

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.

What should I discuss with my healthcare provider before using a fentanyl transdermal skin patch?

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.

How should I use fentanyl transdermal skin patches?

Use this medication exactly as it was prescribed for you. Do not use the medication in larger or smaller amounts, or use it for longer than recommended by your doctor. MISUSE OF A FENTANYL SKIN PATCH CAN CAUSE HARMFUL OR FATAL SIDE EFFECTS.

Read all patient instructions carefully before using a fentanyl transdermal skin patch. Ask your doctor or pharmacist if you have questions.

If the skin must be washed before you apply a skin patch, use clear water only. Allow the skin to dry completely before applying the patch.

Do not use soaps, oils, lotions, alcohol, or other chemicals on the skin where you will apply a fentanyl transdermal skin patch. These substances could increase the amount of fentanyl that your skin absorbs, possibly causing harmful effects.

Apply the skin patch to a flat, dry, hairless area of the chest, back, side, or outer side of your upper arm. To remove any hair from these areas, clip the hair short but do not shave it. Press the patch firmly with the palm of your hand for 30 seconds. Make sure the patch is sticking firmly, especially around the edges. You may wear the patch for up to 72 hours. Never wear more than 1 fentanyl transdermal skin patch at a time.

After removing a skin patch fold it in half, sticky side in, and flush the patch down the toilet. Apply a new patch to a different skin area on the chest, back, side, or upper arm. Do not use the same skin area twice in a row.

Do not use a fentanyl transdermal skin patch if it has been cut or damaged. Doing so could expose you to too much fentanyl, which can cause a life-threatening overdose.

Store the skin patches at room temperature. Keep each patch in its foil pouch until you are ready to use it.

Keep track of how many skin patches have been used from each new package of this medicine. Fentanyl is a drug of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.

What happens if I miss a dose?

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.

What happens if I overdose?

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.

What should I avoid while using a fentanyl transdermal patch?

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.

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. Tell your doctor about any unusual or bothersome side effect.
