Despite doctors motivation

1.5 years ago I moved over to a diabetes drug, Victoza. This was due to my diabetes being inadequately controlled. Although my long term levels (Hb1AC) seemed ok, I suffered from spikes in blood sugar and also lows(due to the meds I took). Victoza gave me a new lease on life. I paid for this out of pocket. I app**** to for chronic cover last year and was refused. I app**** this year again having upped my plan to comprehensive. Discovery refused . Their reason was I did not meet the requirements without specifying the requirements. Previously the reason given was that in their opinion there were other meds. that was more suitable. My doctor disagrees...so do I. The only conclusion is that they refuse due to to the cost. This is short sighted as my risk of complications decrease significantly with tighter diabetes control and so will their long term cost if my diabetes is managed properly. I also have to assume they don't take all factors into consideration as my doctor has done. Stopping this drug effectively robs me of the chance at controlling my diabetes and leading a relatively normal life. I am still trying to get them to see my point of view - this is a challenge
