How to Use This Medicine:

Patch

  • 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.
  • This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
  • 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.

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:

  • 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.
  • Keep all medicine away from children and never share your medicine with anyone.

Drugs and Foods to Avoid:

Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.

  • Make sure your doctor knows if you are using other blood pressure medicines (such as atenolol, metoprolol, nifedipine, verapamil, Inderal®, Lotrel®, Norvasc®, Tenormin®), digitalis, or medicines to treat depression (such as amitriptyline, doxepin, nortriptyline, Elavil®, Pamelor®, Sinequan®).
  • Tell your doctor if you are using any medicines that make you sleepy. These include sleeping pills, cold and allergy medicine, narcotic pain relievers, and sedatives.
