30 days to trash?

I’m new to insulin use and am wondering if everyone really tosses their insulin in the trash 30 days after opening?

here’s a discussion we had on the subject of “refrigerate or not”. hope this helps!

Only if it wasn’t keep refrigerated.

Bob,

I rode cross country on my bicycle unsupported 2007 and I used iinsulated foil lined box for my insulin. Monitoredt my BG very closely did not have any problems. Very similar preparation for multiple week backpacking trips as well. I never refrigerate after opening bottle
