As I said, insulin transported at wrong temperature can go bad.
The insulin I take is really clever stuff, releasing over time from one injection. But if it gets too hot or cold it is buggered.
So what we need is a clever means to include in the insulin something that changes colour dramatically if outside these temperature, but is also safe to inject.
That way, badly stored insulin could turn red or some such.
Surely this is possible?
P.S. As people have pointed out, far safer to have something external on the pen that shows out of temperature at some point, and no need to make it actually safe to inject.
P.P.S. Surprised manufacturers don't do this, as they would sell more where it was badly transported :-)
