What is this medicine?
FENTANYL (FEN ta nil) is a pain reliever. It is used to treat breakthrough cancer pain that your long acting pain medicine does not control.

The medicine is used only by people who have been taking an opioid or narcotic pain medicine for at least a week.
How should I use this medicine?
Follow the directions on the prescription label. Cut open the package using scissors, and remove the unit. Do not open the package until you are ready to use it. Place the unit in your mouth between your cheeks and gum and suck on it. Move the unit from one side of your mouth to the other every couple of minutes. Twirl the handle often.

Then, throw the handle away out of the reach of children and pets. If you did not finish the entire unit and you cannot immediately get rid of the medicine, put the unit in the temporary storage bottle that you have received in the Welcome Kit. Push the unit into the opening on the top of the unit it falls completely into the bottle. NEVER leave unused or partly used units where children or pets can get to them. Empty the storage bottle, and run the handles under hot tap water to get rid of the medicine at least once a day.

What should I watch for while using this medicine?
Tell your doctor or health care professional if your pain does not go away, if it gets worse, or if you have new or a different type of pain. You may develop tolerance to the medicine. Tolerance means that you will need a higher dose of the medicine for pain relief. Tolerance is normal and is expected if you take the medicine for a long time. If you need to use more than 4 units per day, call your doctor or health care professional. If you do not finish the whole unit each time you have an episode of breakthrough pain or your if pain is not relieved after finishing a whole unit, call your doctor or health care professional.
Do not suddenly stop taking your medicine because you may develop a severe reaction. Your body becomes used to the medicine. This does NOT mean you are addicted. Addiction is a behavior related to getting and using a drug for a non-medical reason. If you have pain, you have a medical reason to take pain medicine. Your doctor will tell you how much medicine to take. If your doctor wants you to stop the medicine, the dose will be slowly lowered over time to avoid any side effects.
There are different types of narcotic medicines (opiates). If you take more than one type at the same time or if you are taking another medicine that also causes drowsiness, you may have more side effects. Give your health care provider a list of all medicines you use. Your doctor will tell you how much medicine to take. Do not take more medicine than directed. Call emergency for help if you have problems breathing or unusual sleepiness.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medicine. Avoid alcoholic drinks.
The medicine will cause constipation. Try to have a bowel movement at least every 2 to 3 days. If you do not have a bowel movement for 3 days, call your doctor or health care professional.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water may help. Contact your doctor if the problem does not go away or is severe.
