How long after the date Betamethasone dipropionate Drug expiration date?

The 'expiration' date is the last date that the Manufacturers will guarantee their product. In no way, does it mean it mysteriously stops working at midnight. As long as the product is helping, it works.

Expiration means to die. The med is dead that day, and probably isn't as strong. An expiration date is saying I'm dead get rid of me.
