Well, you can ask your doc about stopping one or the other of your 2 meds to get a clearer idea of which med may be helping and which may not be.

I generally try to only change one med at a time but in Nov, I started both Trelegy & Dupixent. I’m doing better than last year and don’t honestly know how much to attribute to each medication. At this point, I’m just happy to be more stable and have fewer exacerbations so I’m sticking with the new combo.
