Carol, you may just be fine if you don’t I the antibiotic treatment. It’s a decision that ultimately you need to make with as much information as you can find. Many of us have declined the antibiotic regimen while many others have successfully gone through treatment. It depends on how bad your bronchiectasis is and how bad your MAC symptoms are (if you have any). But you do need to do airway clearance with nebulizing 7% saline. It has kept the MAC suppressed in many, including myself. I was diagnosed almost 2 years ago and my last sputum test have not shown MAC. That’s not to say it’s gone.
