Putting Air in the syringe and into your vial.

[FartfulCodger]

Try drawing the last dose out of a 60mg vial without injecting air. Good luck with that.

Exactly. You've gotta see-saw that plunger to get out every last drop!

I mean nurses are taught to pull air into the syringe on day 1 in nursing school.

This is one of dozens of reasons I went to pens really early on, and was glad my mom came to the same conclusion for her own stuff. No air, and no vacuum to fight.

To be or not to be. I read things every day that putting air in the syringe can contaminate the vial. I personally don’t do it. But I have a few friends that do. My philosophy is the more sterile the protocols used the better off your peps will be.

I only recon in front of my flow hood, so all air going into a vial is clean.
I use pens as well.
