FENTANYL (FEN ta nil) is a pain reliever. It is used to treat persistent, moderate to severe chronic pain. It is used only by people who have been taking an opioid or narcotic pain medicine for more than one week.
Apply the patch to your skin. Do not cut or damage the patch. A cut or damaged patch can be very dangerous because you may get too much medicine. Select a clean, dry area of skin above your waist on your front or back. The upper back is a good spot to put the patch on children or people who are confused because it will be hard for them to remove the patch. Do not apply the patch to oily, broken, burned, cut, or irritated skin. Use only water to clean the area. Do not use soap or alcohol to clean the skin because this can increase the effects of the medicine. If the area is hairy, clip the hair with scissors, but do not shave.
Take the patch out of its wrapper, and take off the protective strip over the sticky part. Do not use a patch if the packaging or backing is damaged. Do not touch the sticky part with your fingers. Press the sticky surface to the skin using the palm of your hand. Press the patch to the skin for 30 seconds. Wash your hands at once with soap and water.
Keep patches far away from children. Do not let children see you apply the patch and do not apply it where children can see it. Do not call the patch a sticker, tattoo, or bandage, as this could encourage the child to mimic your actions. Used patches still contain medicine. Children or pets can have serious side effects or die from putting used patches in their mouth or on their bodies.
Take off the old patch before putting on a new patch. Apply each new patch to a different area of skin. If a patch comes off or causes irritation, remove it and apply a new patch to different site. If the edges of the patch start to loosen, first apply first aid tape to the edges of the patch. If problems with the patch not sticking continue, cover the patch with a see-through adhesive dressing (like Bioclusive or Tegaderm). Never cover the patch with any other bandage or tape.
To get rid of used patches, fold the patch in half with the sticky sides together. Then, flush it down the toilet. Do not discard the patch in the garbage. Pets and children can be harmed if they find used or lost patches. Replace the patch every 3 days or as directed by your doctor or health care professional. Follow the directions on the prescription label. Do not take more medicine than you are told to take.
A special MedGuide will be given to you by the pharmacist with each prescription and refill. Be sure to read this information carefully each time.
Talk to your pediatrician regarding the use of this medicine in children. While this drug may be prescribed for children as young as 2 years old for selected conditions, precautions do apply.

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.
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 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.

If you are going to need surgery, a MRI, CT scan, or other procedure, tell your doctor that you are using this medicine. You may need to remove this patch before the procedure.
