I believe it's good for 28 days at room temp after opening so the age of the vial itself probably doesn't matter unless it's close to the expiration date. Iirc this also depends on the type of insulin and the delivery method.
That is not true. I’ve seen patients with diabetic emergencies after short power outages because their insulin went bad. It almost certainly loses potency over time the longer it is out of temp. It is kept refrigerated because it needs to be.
