Hi All, We have been using the Novolog pen cartridges/vials with syringes for about a year now, but are switching to the NovoPen Jr. in the next couple of days. I still have some pen cartridges left, and wondered if they will work in the Jr., or if I need to get a different size? The pharmacy tech didn't know what I was talking about (they can't seem to wrap their brains around the cartridges being used with syringes and not the pens...I always lose them at that point and get passed around until someone is willing to take my word for it), and put me on hold for the pharmacist, but I just waited forever and then was disconnected. Anyway, I thought I'd probably get a faster (and just as accurate, if not more) answer on here. Thanks!
