I am 55 and have been struggling with a yearlong plus flare up that hasn't resolved despite the usual treatment with inhaled steroids (Qvar). A couple of additional things have really helped and perhaps worth considering.
FIrst, I went on spiriva. Its a copd med also used for asthma as a long-acting bronchodiolator which helped a lot.
Also, at my doctor's advice I got a nebulizer. Using 7% saline and albuterol seems like its done a lot to open me up and help reduce some lingering congestion.
I'm back on montelukast. I went off of it bc I wasn't sure it was working after a couple of weeks on it. A new Dr recommended I try it again and it definitely is helping.
Finally, 100mg/daily of coenzyme q10 liquid also seems to help.
Sometimes you really have to throw the kitchen sink at this to make progress! ICS alone never has been enough alone to do the job...
