Pens 'over heating' & not working

Hi, like lots of people I carry my insulin pens around with me, my Novorapid Flex pen.

I've found sometimes that after having my pen In my coat pocket for a few hours means that when I next inject (having worked out correctly how many units I need by carb counting), my sugar will be high.

Does anyone else suffer from this, or agree/disagree and thinks it's not my pen getting too hot to work properly?

If it's close to a source of heat then there's a good chance that the insulin has been spoiled, get yourself a Frio wallet.
 
After reading this , I can relate when I put my novo rapid pen in my inner blazer pocket and do my next blood testing it tends to be on the high side
now I tend to leave my novo rapid in my bag

I'm glad I'm not the only person with this problem. Every single novo pen! It gets to about 50/60% used & it then becomes '****'. The pen in my bayer bag at room temp & still it ends up with bubbles & becomes less effective /:
 
Chelseaace - funnily enough my pen was towards the end of its run, there was less than 50 units in there. So maybe it was that as well. Thanks

This doesn't happen with pumps, and the thing is worn next to the skin so I don't think it gets too hot.
