Hello, and welcome to Mayo Connect. I think we need a little more info about your health and diagnosis, then we can talk about the doctor(s) who are treating you, their recommendations and questions to ask them.
Why? Because MAC (Mycobacteria Aviums Complex) infection can vary in exact strain, the level of illness you are experiencing, all of your health conditions and whether you need antibiotics now, alternative treatments or both.
How and when were you diagnosed? Are you seeing a pulmonoogist or ID doc?

Hi, I am Jane and was diagnosed with mac a year sgo and put on the big 3 - Ethambutol, Azithromycin and Rifampin. There have been some side effects but tolerable considering my cultures are starting to come back negative. I am hopeful but still hesitant as I know it could turn around. Just stay with whatever program they put you on and give it a try. I was very hesitant because of all the horror stories but you have to give it a try it will be worth it. Good luck.
