Hello thanks for your Q
Your medications seems to be quite optimal for management of asthma
mor ethan COPD - so I feel first the diagnosis needs to be confirmed by spirometry
to make sure it is COPD & not asthma.
If above combinations is still not helping with shortness of braesth / if it is getting worse you must been seen by a Dr & also you may need o get tests done ( blood test
, X ray
& lung function check)
Hope that helps
