I have been in the standard 3 meds for three years to treat MAC. I was never told I should get my hearing tested for a baseline but have an appt now to see a doctor. I can tell that I have sustained a tremendous hearing loss as I continually have to ask my husband ‘what’ even though he is only a few feet from me. One serious side effect that is attributed to all three meds is severe dizziness - I have even passed out. This negatively affects my life more than any other side effects. I can’t drive for fear of causing a wreck. I would suggest googling Azithromycin and looking at side effects.
