My pulmonologist suggested I take Mucinex twice a day to thin mucous so I can cough it up if necessary and to avoid mucous plugs. I have Bronchiectasis only. After testing me for asthma, which I did not have, he took me off inhalers because he said studies show they can actually create worse conditions in the lungs for pneumonia. I was hesitant at first because the inhalers seemed to help with breathing, but I have been off of them since March, doing nebulizing treatments twice a day as well as taking the mucinex twice a day.
