There are definitely issues and inconsistencies around dispensing Insulin Pens for people, as there are for getting people on to systems like the Freestyle system. I suspect - but cannot prove - that it is all to do with GP budgets as, if I am correct, these are charged back to the local practice budget and are not always cheap (my eldest son - also T1 - had to buy a Freestyle sensor whilst on holiday after he had his pulled off his arm; the local pharmacy charged £60 for a single sensor...). I noted with dismay that NICE (I'm guessing) have also removed blood testing meter sensors off repeat prescriptions for Type 2 diabetics as well, probably for much the same reason. If ever there was a route to people suffering poor overall control then that has to be up there with the best of them!
As for your isse, then I would revert back to the Hospital where your specialist is and complain there about the lack of availability of a Novopen, and continue to write - and visit in person demanding to see the Practice manager - until this is resolved. Patience and strong persistence in equal measure seems to be the only way to get success in the NHS these days!
