How to Use This Medicine:

Patch

  • This is a very strong medicine. This medicine can cause trouble breathing and other serious health problems, including death. No one else should ever use your patch for any reason. Talk to your doctor if you do not understand the directions or warnings.
  • Your doctor will tell you how many patches to use, where to apply them, and how often to apply them. Do not use more patches or apply them more often than your doctor tells you to.
  • Wash your hands with soap and water before and after applying a patch.
  • Fentanyl skin patches come in sealed pouches. Do not use this medicine if the pouch seal is broken or if the patch is cut, damaged, or changed in any way.
  • Leave the patch in its sealed wrapper until you are ready to put it on. Tear the wrapper open carefully. NEVER CUT the wrapper or the patch with scissors. Do not use any patch that has been cut by accident.
  • Do not use soap, lotion, alcohol, or oil on your skin before you apply the patch. Wash the skin only with clear water. Let your skin dry completely. Do not shave the skin where you will apply the patch. If you must get rid of some hair, cut the hair with a pair of scissors.
  • The patient instructions will show the body areas where you can wear the patch. When putting on each new patch, choose a different place within these areas. Do not put the new patch on the same place you wore the last one. Be sure to remove the old patch before applying a new one.After you apply the patch, push down on it with the palm of your hand for 30 seconds to make sure it sticks to your skin.
  • For young children and people with a loss of mental function, apply the patch where it cannot be reached, such as the upper back. Check the patch occasionally to make sure it is still okay.
  • Do not put the patch over burns, cuts, or irritated skin.
  • Put on a new patch if the old one has fallen off and cannot be reapplied.If a patch is loose, tape it to your skin with first aid tape.
  • Never put the patch in your mouth.
  • Wash off any gel that gets directly on your skin right away with clear water. The gel is only supposed to go through the patch and onto your skin.
  • Water should not affect the patch. You may take a shower or go swimming while you wear it.
  • Drink plenty of liquids to help avoid constipation.
  • This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.

If a dose is missed:

  • If you forget to wear or change a patch, put one on as soon as you can. If it is almost time to put on your next patch, wait until then to apply a new patch and skip the one you missed. Do not apply extra patches to make up for a missed dose.

How to Store and Dispose of This Medicine:

  • Store the patches at room temperature in the original package, away from heat, moisture, and direct light.
  • This medicine can cause serious side effects if used by adults or children who are not used to strong narcotic pain medicines. Make sure you store the medicine in a safe and secure place to prevent others from getting it. Keep the medicine away from pets.
  • Throw any used patch away so that children or pets cannot get to it. There is still enough medicine in a used patch to make a child or pet very sick. Fold a used patch in half with the sticky sides together and flush it down the toilet, and then wash your hands thoroughly with soap and water. You may also place the used patch in the patch disposal unit to be thrown in the trash. When you stop treatment, take all of the leftover patches out of the packages, fold them in half, and throw them away.
