Humalog 25 insulin

Hello, just wondering does anyone know if the humalog 25 insulin cartridges fit into the novopens?

My doc wants to put me on this insulin as mixtard 30 is due to be discontinued :-( I have big issues with injections and it has taken me years to get used to it, now i am comfortable with these pens and dont want to change. Just the thought of starting again is driving me mad - i know this may sound stupid to all you diabetics who can easily inject themselves but this is much a big deal for me and my doc doesn't understand.

Typically the humalog and novalog cartridges are not interchangeable, so my assumption would be that they will not fit your current pen. I know it may be disruptive to change pens, but hopefully you can find a new one that makes it equally comfortable over time.
