Two days ago I purchased 2 vials of insulin. I usually buy 2 at a time.
Insulin I purchased had expiration of 2/10.
I read on line about the expiration dates on insulin. I read the strength will become less after time, even if it has not open. Is this correct? Usually vials are a year or more from expiration when I get them. One replaced today does not expire till 2012. They would not replace one that had the box open, even though seal was not broken. Is this insulin still as effective as it should be? Should I just consider a loss and go right to the 2012 vial?
Thanks!
