@suzyq61 if you are having difficulty walking around the house, I would definitely call your Dr or his NP back and tell them you need this immediately. I’m sorry, I don’t know if you are from the US or not, but in US my Dr has samples of Brexit and Trelegy available. Just ask for them. I asked my Pulmonologist for Trelegy , along with Brexit, so I could alternate them. That seemed to help me. It wouldn’t hurt to try. My Pulmonologist didn’t think it was an issue. Also, are you using nighttime oxygen? I have emphysema, probably end stage or close enough, that I use oxygen during sleep. It seems to be helping me especially in the mornings.

But personally, I would call again or drive over if it’s not inconvenient and ask for samples plus possibly a Trelegy prescription to alternate. You have to be your own advocate . This is not medical advice it’s just what is helping me for now. Wishing you the best
