Insulin air bubbles

I opened a new pen vial of novorapid yesterday. I now notice lots of tiny air bubbles in the vial. I always prime and use a new pen tip for each injection. I know we all see air bubbles in our insulin vials at times but are so many tiny ones normal ?

Hi @Sharrryn No right or wrong answer to this one - as long as your tapping the vial and priming your pen it won't be an issue,
 
For purposes of injecting via a pen this should be okay. If I get air bubbles when filling a pump cartridge it causes a problem with insulin delivery but not a safety problem for a subcutaneous jab via a pen.
