this isn't a problem at all with humalog and nph (insulins i've used, no experience with lantus, but i don't see a problem). i don't want to say anything concrete but i'm pretty sure insulins can stay out of the fridge for up to 30 days as long as it isn't exposed to extreme temperatures (above 30, i think). before i got my pump my humalog pen was never in the fridge since i tried to take it everywhere with me. just in case of a spontaneous snack or meal out. considering an insulin pump isn't refridgerated you know insulin has to be good for at least 3 days outside the fridge because it has to be in your pump. the little info sheet that comes in the box of insulin should have some information.
