The long-time Unlimiteds have already seen this kind of stuff. But for newer members, I wanted to share it with a new demo.
I am calling this a “demo” instead of an “experiment”, because really by now, there is no more experimenting. I know what is going to happen, I am just trying to show it.
Perhaps you recall this one from last year:
That was a fun thread! And it was a little bit different, it was in a hot car in the summer for 4 days.
But since people may still be worried about leaving insulin out of the fridge, I did it again, but in a different way.
Take a look at these pics, and notice two things.
I made a note of the date I took it out of the refrigerator. It has been unrefrigerated for over a year!
And check out the expiration date. Almost 4 years past expiration!
Other than normal basal, my last insulin bolus dose was 10pm LAST NIGHT. Over 15 hours of nothing but basal insulin.
Then I did a normal dosing amount for lunch, using my unrefrigerated and extremely expired insulin!
Here is the obligatory Dexcom trace. Where is the horrible insulin degradation? I can’t find it. At the time of writing this it has been 3 hours since my lunch, and I am still looking for the insulin failure.
What I am NOT saying is that this is how you should treat your insulin. Don’t purposefully leave it in a hot car, don’t purposefully leave it unrefrigerated for over a year, don’t purposefully let it expire and use it 4 years later.
But what I am saying is - relax about it a bit. Insulin is much tougher than people think.
