Recently diagnosed with a form of COPD, the Anoro prescription instantly worked like a miracle for my shortness-of -breath-on-exertion. Doc gave me free trial month coupon. Now I find that Anoro is Tier 3 drug and my Medicare D charges $215 for 30 day supply. I am on Warfarin 5mg/day blood thinner and this may be limiting factor. Will ask lung doc for alternative but looking for helpful perspectives.
