@kevin7 Welcome to Mayo Connect, where we are patients supporting one another in the journey of living with Bronchiectasis. Even though I have not taken Azithromycin alone, I am jumping in to greet you because the members in this discussion, except @spider109, are no longer active in our group. Here are a few questions to help us learn more about you:

How recently were you diagnosed? Are you also doing airway clearance to help keep your lungs clear? Have you been diagnosed with MAC through sputum culture or bronchoscopy, or is this just a shot in the dark by your doc?
