Default Re: Insulin and Expiration Dates ?

I concur with your thoughts Patty. I find the need to replace Mil's NPH every month now with her Humalog lasting much longer.

Your mention of keeping a vial of Humalog for 6 months is current vial of Humalog is at 2 1/2 months and still with good results.
With the price of Humalog I am seeing just how far it will stretch as in the past I have replaced it every 60 days.

But, as I stated previously and what you state now...I do think there's a difference in how long a vial can last based on whether it is a clear insulin or one requiring mixing.
