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.
- The patch should be left on your skin for 7 days. Follow your doctor's instructions carefully. Do not remove the patch without your doctor's approval. Even if you feel fine, your blood pressure can still be high.
- 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 that has very little hair or no hair. 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.
- Leave the patch in place even when showering, bathing, or swimming. If the patch loosens, cover it with an extra adhesive overlay that is provided in the box.
- This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
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
