Expired Tresiba

[lh378]

Has anyone used expired Tresiba that have been kept in the refrigerator? It would seem like a waste to throw them away. Expired Novolog works fine. Novolog that has been “opened” for more than 30 days work too.

There’s been a lot of very useful discussion on this topic in the boards - here’s one reference

The great unrefrigerated (& expired) insulin demo

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: car-baked-insulin-an-experiment-for-irish 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 …

Now I don’t know if Tresiba is explicitly addressed on this topic, but it might well have been.

Good luck!

I think we know through experimentation that Novolog and Humalog are really really robust and work fine in an expired state. I know through experimentation that Lantus worked fine for us expired. But I don’t recall anyone testing Tresiba. You willing to the guineapig? Would be cool data to provide to the community. Something like test it once per quarter starting at expiration…

I have one pen that is expired by one month. It seems to be fine.
