Have you tried albuterol, it’s not clear from your post? Back in the day, long before BE/NTM, I think I was in my 20’s, I had a cold with cough and the cough I could not shake and it went on and on and seemed to be almost self-sustaining, the more coughing the more coughing. I was actually at the dermatologist and she was like “whoa, what’s going on”, I explained I wasn’t contagious anymore just had this crazy dry cough with a life of its own. She sent me to urgent care to get an inhaler. She said the cough from the cold irritated my airways and I needed to calm that down to break cycle. They put me on an albuterol inhaler, a few days later the cough stopped. It was like magic. Obviously, many here are dealing with more complicated issues but to your specific question as to whether albuterol can help with cough I can definitely say it did for me. I think one factor may be whether your husband cough is dry or wet/productive. If dry, I would definitely talk to his medical team about albuterol or something similar. If it is a wet/productive cough, that sounds like an exacerbation which may need antibiotics. I agree with others about reaching out to medical team to puzzle through.
