I didn't know the profile of both inhalers so appreciate you sharing that info. I’m absorbing so much information here about this process and treatments. Both inhalers were prescribed by my pulmonologist following my latest PFT. I started on BREYNA but then they added in the Spiriva at the next follow up. I did ask about the exact question you posed, does Spiriva replace the BREYNA, but even in my MyChart summary it’s lists taking them both. The PFT showed my results improved after using an inhaler so with the suspected asthma component and continued shortness of breath this was the recommended therapy. I do go back in October so will certainly ask. I believe they did say there is an inhaler with is a combination so you don’t need multiple ones?
