No that was an example of how your reasoning does not compute. You are saying because i put this is a vial that extends the expiration date out a year that means that the expiration date is longer than what the manufacturer stated. With your reasoning i could go through the pharmacy take all my close dated items and put them in amber vials then i could use them for one more year. In that case why do we do outdates at all we could just keep everything and dispense it whenever and say the date that the computer came up with, which will always be a year out is right.
