Listerine StripsPosted on January 12, 2010. My Listerine whitening strips OK to use after "date? I got my Listerine strips some time, thinking it would be exhausted around 11/08. I read yesterday on the back of the box, it prints USE BY 09/2008. Is it safe for me to finish using all the bands of 1-2 weeks (have not really started yet) or should I throw them out? They should still be fine. If anything they are simply less effective after the expiration date, is not dangerous. Hydrogen peroxide decomposes in the water.
