I was assuming that Lucy's ProZinc would be safe to use until the expiration date on the vial. Which is 7/2014. Of course it will be used up way before then, but is it true that it loses potency after just a couple of months? I punctured this vial for the first time 12/19/12.
 
Joan,
Only last week? If so, it's gotta still be good, I would think. Can you go to the prozinc website and send them an email?

My vials usually last 4-6 months. As long as it looks the same (no "floaters") & stays refrigerated, it's theoretically good until it expires. It can go bad sooner (officially, you have a month after it's opened), but typically it's "good to the last drop."
 
I'm not worried about this particular vial. Just in general. Arè we supposed to replace the bottle after X amount of days, weeks, or months after breaking the seal and puncturing it?
 
It's probably EVID - every vial is different. :mrgreen: As long as the numbers are consistent, as Lisa said, no floaties, the vial is presumed to be fine. Some people use it to the last drop; some may decide a vial is losing its punch and not bringing the numbers down, and so switch out before it's completely gone.
 
I decided to phone ProZinc. Had to navigate through just two phone trees, and

Whoops, Holy Toledo, typo: I punctured it 9/19/12. :oops: Can you imagine having to buy a ninety dollar vial once a week? Second mortage, here we come.
I decided to call the company that manufactures ProZinc. I was told that if stored correctly, ProZinc is stable and good until the expiration date on the bottle. A tech at the vet's office set me on edge, telling me I should replace the bottle after a couple of months. The rep at ProZinc said human insulin needs to be discarded within 30 - 60 days, maybe that was what the confusion was all about.
Don't know why I was so reluctant to call the company myself and ask, but I'm glad I did.
