What should I tell my health care provider before I take this medicine?

  • breast cancer
  • diabetes
  • heart disease
  • kidney disease
  • liver disease
  • lung disease

How should I use this medicine?

Apply these patches once daily, at the same time every evening. Follow the directions on the prescription label. Open the pouch and remove the patch. Remove the protective liner and silver disk from the patch. Apply to a clean, dry area of intact skin on the back, abdomen, upper arms, or thighs. Do not apply to a bony area like the hip or shoulder or an area that might receive a lot of pressure while sitting or sleeping. Do not apply to the genitals or scrotum. Remove and replace the patch as directed every 24 hours, applying a new patch to a new site. When you remove a patch, do not place another patch on the same spot for at least 7 days. The patch may be worn during sex, showering, or swimming. Excessive sweating or strenuous exercise might cause the patch to loosen or fall off.

Talk to your pediatrician regarding the use of this medicine in children. While this skin patch has been used in males as young as 15 years of age, precautions may apply.

What if I miss a dose?

Try not to miss a dose. If the patch becomes loose, simply smooth it down again around the edges. If a patch is forgotten or falls off before noon, apply a fresh patch and wear it until you get back on your normal schedule that evening. If a patch is forgotten or falls off in the afternoon or later in the day, do not use a new patch until it is time for your next evening dose. Do not use double or extra doses.
