@wangling... I use albuterol twice a day in my nebulizer with two other asthma meds. My MAC infection was in the lower right lobe and destroyed its function. Albuterol opens up the airways enough to allow the mucous to drain out, but recently I needed to add a flutter device to move the deepest mucous, since my bronchial tubes are now closing when I cough. I used to get infections when I couldn't get enough albuterol. I'm doing well now that I have a larger prescription on auto refill. I use postural drainage daily. Made it through COVID without complications. It's the right med for me.
