Levemir

I have been using Novorapid and Levemir for many years, a few months ago I did my morning bg test and could not understand why it was so high, had a day of not eating a lot as bg always high, next morning same again checked Levemir pen and noticed when I removed needle cover it was wet removed the vial and twisted the top which came away in my hand checked another vial and it had a crack in it. This morning bgs high again checked Levemir vial and yes a crack looked at another one it also had a crack in the vial. That has been four faulty Levemir vials in the last six months and no problems with the NovoRapid vials. If you start getting crazy bg readings for no apparent reason check your insulin vials.

I take it you use actual pens as opposed to disposables?

Yes been using pens for a good few years and had no problems, thought it was maybe the way I have been carrying the spare insulin with me but for some reason just the Levemir vials have been faulty.
