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.
- 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.

- You may take a bath, shower, or swim while wearing a patch. Do not expose the patch to the sun for long periods of time.

- Fold the used patch in half with the sticky side together. Throw it in the trash, out of the reach of children and pets. Do not flush the patch down the toilet.
- 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. Never wear 2 patches at the same time.
