One , somewhere on packaging there WILL BE AN EXPIRATION DATE , so go with that … 2 , everywhere that I've read and that I have been taught says that freezing insulin DESTROYS IT , yes RUINED !!!!!!!!!!!!!!! If frozen just throw it out its GARBAGE !!!!!!!!!! Just read about a young lady that ended up in hospital because of her insulin being no good due to getting too cold …

OK I was taught that freezing insulin destroys it also. However tells of an experement where the insulin was put in the freezer and the subject, a t 1 named Madeline tried it and here is the account from the site >>"Humulin—unopened—has a shelf-life of at least one year at room temperature. And Humulin can be frozen without ill effects to the user. Lilly won't tell you this, but I know of a type 1 diabetic who froze a year's supply for Y2K.

Her name is Madeline and in 1999 she called me to ask if I knew if insulin could be safely frozen. I told her that I didn’t know, but I would find out. Several of us in Medical Corps started making calls and found out it could. I relayed the good news to Madeline.

I suggested that if she were going to freeze it that she keep a log of her blood sugar test values with un-frozen insulin and then with the frozen insulin. She did and her blood sugar did not vary. In fact, Madeline still practices that type of preparedness with her disease."<<

I can see Lilly's agenda for telling us it is no good after being frozen but what would the agenda be for Chuck Fenwick to tell us the opposite?

As it says in Alice in Wonderland: "Couriser and Couriser!"

I think you can "stick a fork in it" it is long past its useful life under any circumstances.

On Lantus see the article here ~

For Humulin see here ~

But maybe I was too hasty with my "stick a fork in it" remark. While researching the length of time Humulin can be kept, I came across this little tidbit ~

So maybe the thing about not using insulin after freezing is not valid after all? Hmmmm!

I don't know if what the mfr says is bogus or not about freezing insulin but since you have excess insulin you might just try freezing it and if you or someone else needs it in case the "big event" happens (whatever it may be) it would be there for you.
