revolution: how old is too old

Saw this same question recently about Frontline and read that it didn't expire. Would the same apply to Revolution?

SIL's dog came to live with us after SIL passed away. We've found several boxes of Revolution at the house dated '05 and '06 plus some newer that obviously are fine.

Is it safe to use the older ones first? Thank you, Sandy
