- Leave the patch 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.
- 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 you shower, bathe, or swim. If the patch loosens, cover it with an extra adhesive that is provided in the box.
- Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
- 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.
