Hello, I was just wondering what the deal is with unrefridgerated insulin, does it become more dangerous or is it just less effective. I have 2 novarapid flex pens, the expiry date is not untill 2015, but the pens are suppost to be kept refridgerated untill use then discarded after 30 day. The pens havnt been opened but they have just been kept in cupboard. Your thoughts please.
