During your 3 weeks on 1 week off patch cycle you should put your new patch on immediately after you take the old one off during your 3 patch-weeks. You should not go more than 7 24-hour days without applying a new patch after your patch-free week. If you do go more than 7 24-hour days without applying a new patch then you should use back-up for at least the 7 days of your first patch of the new cycle. Take a look at the patient info. leaflet that came with your patches to see the manufacturers instructions for how to use your patches correctly and for precautions to take if you mess-up.
