? Medical newbie whack-a-mole INSULIN STORAGE

Hello
Something new occurred to me…. should my insulin pen have oxygen in it?
I thought the answer was no

 

If you use a syringe to to draw insulin out of a pen some air gets into the pen. It should not have any effect since if you use a vial you inject air into the vial equal to the insulin you want to draw out

 

Great thank you! Thats a relief

 

It's not uncommon to have a few bubbles. You just don't want to inject air into the pen.
