From what I have managed to glean from various sources - a vial of insulin used in a pen injector should be discarded after 25 days of use. Not being refrigerated, it is subjected to room temperature or ambient temperature depending on how it is stored in transit.
From my own experience, I have noticed that insulin over a certain time frame tends to be less effective. Seasonal temperatures can play a significant role in the performance of insulin over time. I date all vials used in my Novopen3 and Lantus pen to 25 days in winter and 20 days in summer to avoid expiry of insulin. Better safe than sorry!
