I started taking Advair 2 years and it has helped me tremendously. However, I did notice some side effects like the dryness of throat and the constant need to clear my throat which I can live with. My main concern is blood sugar levels. I have been told by my doctor over the last year that my blood tests shows I have hit the diabietes numbers on the fasting tests. Is this a side effect of Advair? Is there anyone out there that has experienced this?
