This medication is used to help relieve severe ongoing pain (such as due to cancer). Fentanyl belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain.
Do not use the patch form of fentanyl to relieve pain that is mild or that will go away in a few days. This medication is not for occasional (“as needed”) use.

Read the Medication Guide and, if available, the Instructions for Use provided by your pharmacist before you start using this medication and each time you get a refill. Learn how to properly use, store, and discard the patches. If you have any questions, ask your doctor or pharmacist.
Use this medication on a regular schedule as directed by your doctor, not as needed for sudden (breakthrough) pain.
Before you start using this medication, ask your doctor or pharmacist if you should stop or change how you use your other opioid medication(s). It may take up to 24 hours before you have pain relief from fentanyl patches. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using fentanyl safely with other drugs.
Apply this medication to the skin as directed by your doctor. Do not apply on burns, cuts, irritated skin, or skin that has been exposed to radiation (x-ray treatment). Select a dry, non-hairy area on a flat part of your body, such as the chest, sides, back, or upper arms. In young children or in people unable to think clearly (such as due to dementia), apply the patch on the upper back to lessen the chance it might be removed or placed in the mouth. If there is hair on the skin, use scissors to clip the hair as close as possible to the skin. Do not shave hair since this might cause skin irritation. If needed, use water to clean the area. Do not use soap, oils, lotions, or alcohol on the application site. Dry the skin well before applying the patch.
The patch is usually changed every 72 hours. To avoid irritation, apply to a different area each time. Be sure to remove the old patch before applying a new patch. The used patch still contains enough fentanyl to cause serious harm, even kill a child or pet, so fold it in half with the sticky sides together and discard properly. Do not let children see you apply a patch, and do not apply the patch where children can see it. Children have found patches that have fallen off or removed patches on sleeping adults and put them in their mouths or on their bodies with fatal results. (See also Warning section).

Some of these side effects may decrease after you have been using this medication for a while. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
To prevent constipation, eat dietary fiber, drink enough water, and exercise. You may also need to take a laxative. Ask your pharmacist which type of laxative is right for you.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
