About half of all people who use the patch experience mild skin itchiness or rashes, but fewer than 5% have to stop using the patch because of it. The rash is generally caused by a reaction to either the adhesive on the patch or the nicotine in the patch. You can help avoid skin irritation by putting the patch in a new place each time.
You can try treating the rash with over-the-counter hydrocortisone cream (1%). If the rash is severe, call your doctor.
