I use Trelegy Ellipta. I have done very well with it, though I did have an exacerbation 9 months after starting it. It is expensive and this year I am going to have to pay about $427 for a 90 day supply once I am through Stage 1. I pay $131 in Stage 1 but my insurance currently pay $1709 for 90 day supply so 25% of that is what I will pay for rest of this year. You only need to use 1 dose daily. I also take Daliresp, an oral med, for COPD. That one is pricey too. Insurance price is over $1000 so I will pay $250+ after Stage 1.
