Default Re: Insulin and Expiration Dates ?

I completely agree with you Natalie. Regulations say that there must be an expiry date on the insulin so that it can be guarateed until this date. There is no way it will, as you put it, " magically cease to work..."
I would imagine if the unopened vial had been stored properly in the fridge it will still be good long after the printed date.
