So, I am having a very frustrating moment...we've had two bad vials of insulin. I went through all the appropriate steps to make sure that it was the insulin and nothing else causing the extremely high numbers, so I know it is the insulin but I don't know why. I called the mail order pharmacy to get them replaced and they said they don't do that. They told me I'd have to go through the company that manufactures the insulin. I called Lilly to get the bottles replaced and they will only do a "grace" replacement of 1. I am really confused about who is responsible for this. I don't know if it went bad in delivery, storage from the warehouse, or what. We've been doing this for over 7 years so I know how to handle and store insulin. We've never had two bad bottles and I should clarify, one was bad in end of jan/feb and the other just this week...so it wasn't back to back vials. And it was right after we opened the vials, so numbers were in range then we did a site change and within four hours BG went really high. Anyhow, I need advice - what should I do? We are getting one bottle replaced, but what about the other?
