A general rule of thumb is one year after the fill date. After that it can lose potency.

The reason there is a discard date is because you are supposed to discard it. After that date, there is no guarantee its as good as it should be. Also, with liquids there is always the chance of the fluid evaporating, thus making a more concentrated solution of medication, so you are getting more then you should.
