Change your patch on the same day each week to stay on schedule.

Do not apply a skin patch to your breasts. Do not apply a patch where it might be rubbed off by tight clothing, such as under an elastic waistband.

If a patch falls off, try putting it back on to a different skin area, pressing the patch into place for 10 seconds. If the patch will not stick you may apply a new one.
