I was diagnosed with COPD in 2002 after having a PFT done. I also had a chest x-ray taken, which I'm told was normal, although I have never been shown the x-ray. The dr. prescribed Azmacort Inhaler, 20GM/100MCG, two times a day; Serevent Diskus, 50 MCG/60 puffs, two times a day, and a fast acting inhaler, Albuterol, 17GM/90MCG, as needed. Is this a good combination? The cost is rather high for both the Serevent and the Azmacort. Would I get the same results if I asked the dr. to take me off the Azmacort or the Serevent?
