It doesn't sound great. I use that pen. So far no problem, but there is a supply shortage with some meds. I would think there might be a substitute if push comes to shove, but not certain.I’ve been a Type 1 for 53 years and this week I received a message from my GP surgery that there is a supply problem (temporary) with novorapid pens I don’t remember ever getting a similar message in all those 53 years should I be concerned?
