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. An overdose can be dangerous. Follow directions carefully so you do not get too much medicine at one time.
- 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 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.
- 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.
- 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.
- Throw any used patch away so that children or pets cannot get to it. Fold it in half with the sticky sides together and flush it down the toilet. 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 a trash can. Do the same with any unused patches.
