Accidentally left Insulin out for 12 hours, is it okay to use until new one comes in?

[Britty]

The one time I decided to ignore my OCD to double check and I left it out...

I got the insulin back in late January. I'm going to order a new batch right away (there goes my idea of ordering from the Canadian Pharmacy since that'll take six weeks I think, and I was planning on doing that in April... and I wanted to do the curve this week too.), but it most likely will not get here for about a week. Is it okay to still use the old batch until then or should I just stop injections?

I'd call my vet, but they're not open on Sunday

OH NO!!! YOU'VE RUINED IT! (...sorry, just couldn't resist...)

SERIOUSLY - it's just fine. Just put it back in fridge. Lantus is designed to be kept out of the fridge for 28 days for humans. We keep it refrigerated to last longer. I've done it several times over the years.

HUGS!! Now have a much better day!

Thanks a bunch for the fast response!

I know it can last ~6 months in the fridge, but it's glad to know it's fine for humans outside for 28 days. I wasn't sure if it already being over a month old would affect it or not. Glad to know I can relax when it does happen in the future.
