Put one patch on a dry area of skin without hair, such as your stomach, upper arm or side. Do not put the patch on burned, cut or sore skin. To apply the patch, place the silver side on your skin and press it firmly for 10 seconds with the palm of your hand. Make sure the patch is flat and smooth against your skin. Wash your hands after putting on the patch. Nicotine on your hands could get into your eyes or nose and cause stinging or other problems.
