Hello Sharon
My wife had MAC (cavities) and bronchiectasis. She was on the 3 big medicines for 2 years and was feeling well while taking them. Stopped for 3 months and unfortunately MAC is back and pseudomonas. Her Dr put her back and the 3 antibiotic (MAC) and Tobramycin for pseudomonas (inhaling), she had been taking them for around 2 months and the situation is better now in general. Waiting for infection disease specialist to advise the best way forward. Hope this helps.
