Thanks, I think I have done this but I will try again. The problem is the air bubble is really big so If I syringe it back into the penfill it will put air in there and maybe degrade the insulin. Also for some reason air seems to get caught in the end of my syringes also near the needle area( they are larger syringes and needles that come with my pump cartridges) and I have to shoot that out because is won’t all go to the plunger.
@Jen I’m using penfills for my novopenjunior. I leave them at room temp for 20 minutes before filling a cartridge and then they go into my novopen and my purse to carry with me. I’m changing the cartridge every 3 days now so they get used pretty quickly. I’m still on old penfills and haven’t used even one of the larger viles I have- I wonder if that will change the air bubble situation though. I think it’s maybe something to do with the syringe.
