When This Medicine Should Not Be Used:

How to Use This Medicine:

Device Assisted Patch, Patch

• 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. An overdose can be dangerous. Follow directions carefully so you do not get too much medicine at one time. Your healthcare provider may prescribe naloxone to treat an overdose. Naloxone is a medicine that can temporarily reverse the effects of an overdose. If you have been prescribed naloxone, or purchased it over-the-counter, make sure your household members know how to use it in the event of an overdose. Emergency help is still needed after naloxone is used because the reversal effects are only temporary.
• Ionsys® device: You will be taught how to use this medicine in the hospital after surgery, but you will not use it at home. Do not leave the hospital with the device on your skin.
• Duragesic® patch:
  • Wash your hands with soap and water before and after applying a patch.
  • 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 this medicine if the pouch seal is broken or if the patch is damaged in any way. If any medicine leaks out of the patch and gets directly on your skin, wash it off right away with water.
  • Do not use soap, lotion, alcohol, or oil on your skin before you apply the patch. Wash the skin only with water and let it dry completely. Do not shave the skin where you will apply the patch. You may cut the hair with 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.
  • Do not put the patch over burns, cuts, or irritated skin.

After you apply the patch, push down on it with the palm of your hand for at least 30 seconds to make sure it sticks to your skin.
  • 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 the edges to your skin with first aid tape. You may instead cover the patch with a transparent adhesive film dressing. Do not cover the patch with any other kind of bandage or tape.
• This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.
• Missed dose: 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.
• Store the patches at room temperature in the original package, away from heat, moisture, and direct light.
• Follow the instructions you receive with the patch disposal unit. You will need to seal each patch in a disposal unit, even if it is a patch you did not use. Make sure children and pets cannot come in contact with used or leftover patches. Wash your hands thoroughly with soap and water after you handle the patch. If you must dispose of a patch without the patch disposal unit, be sure you fold it in half with the sticky sides together so no one comes in contact with the medicine.
• Drop off any unused opioid medicine at a drug take-back location right away. If you do not have a drug take-back location near you, flush any unused opioid medicine down the toilet. Check your local drug store and clinics for take-back locations. You can also check the DEA web site for locations.
