What If the Birth Control Patch Comes Off?
Usually, birth control patches stay on well, although they may occasionally come loose or come off altogether. In any case, if the patch is no longer sticky, if it is stuck to itself or something else, or has anything stuck to it, do not try to reapply the patch (a new patch is necessary). If the patch has been off for less than 24 hours, reapply the patch or apply a new patch as soon as you can and continue with your regular cycle as usual (your regular day for changing the patch will not change). In these cases, no backup birth control is necessary. If it has been more than 24 hours (or if you are not sure how long it has been), start a brand-new, four-week cycle immediately (no matter where you are in the cycle). A backup method of contraception is necessary for the next seven days.
