    Hi - sorry to bother you folks on Xmas Eve....
    Went to get a new unused vial of prozinc from the fridge this morning and realised that it had been stored upsidedown for 7 weeks.
    Is this likely to have caused any harm ? The only possible reason I can think if is because the insulin will have been in contact with the stopper the whole time but surely the manufacturer must allow for that sort of thing.
    Just panicking a little - can anyone help?
    I'll post this on both the main health & prozinc forums as I imagine traffic will be very light today

    I don't think that should make a difference.
    Does the insulin look good, after you have mixed it back into suspension? So it looks cloudy again?
    Are there any remaining "floating" particles after you have mixed it?

    Not frozen at all?
    Protected from light?

    The only thing I can imagine, is that the white part of the insulin will have settled onto the rubber stopper and you just have to make sure to mix it well.
    The stopper was sterile, since you said the vial was unused.

    I can't imagine there would be a problem with the new vial.
