is there an expiration date on the package or prescription?
sometimes medications can loose effectiveness after their expiration date.
if you keep the medication in a cool dark dry area, this can sometimes extend the life of medications.
if they are kept in a warm, moist, humid place, this can often shorten the life of medications.
