I've twice had trouble with malfunctioning Novorapid pens. On changing to new pen, sugar spiked and impossible to get down until I replaced the pen with one from another batch. Maybe this is similar to the problem you've had? Luckily or should I say unluckily, I am still alive after having been diagnosed in December 1952 i.e. 60 years ago. Being experienced I have very understanding Doctors and can still drive, have all my limbs and only use glasses for reading and driving, so live a full land active life for my age.
I just wonder how many diabetics this malfunction may have killed? Maybe this is something the BMA should be investigating. They would not have been lucky enough to tell their stories. Do you think this would be of Press interest. I am so incensed with what happened to me since Thursday and how changing the pen batch has solved the problem, proof that the previous pen was malfunctioning. What other evidence do I need? I know you will appreciate my concerns, not just for me, but for all our other fellow Type 1 diabetics.
GNatalieood luck with your control and finding an insulin pen that suits you.
