When This Medicine Should Not Be Used

How to Use This Medicine


  • 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.
  • Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
  • 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.
  • 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.
  • Apply the patch to clean, dry skin with very little hair, on your back, abdomen, upper arms, or thighs. Apply the patch at about the same time every night.
  • Do not put the patch over burns, cuts, or irritated skin. Do not put the patch on oily or sweaty skin or on a spot that might put extra pressure on it (such as over a joint).
  • Bathing or swimming should not affect the patch. However, wait at least 3 hours after you apply the patch before you wash the skin area or shower or swim. Heavy exercise and sweating may cause the patch to fall off.
  • If the patch becomes loose, smooth it down and press it back onto your skin. If the patch comes off before 12 o'clock noon, put on a new patch, and then replace the new patch at your regular time. If the patch comes off after noon, just wait and put on a new patch at your next regular time. Do not tape the patch to your skin.
  • 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 a closed container, away from heat, moisture, and direct light.
  • Fold the used patch in half with the sticky sides together. Throw any used patch away so that children or pets cannot get to it. You will also need to throw away old patches after the expiration date has passed.
