@12818terry11t, Hi Terry. When you were taken off meds and testing negative for mac, were you not taking any kind of antibiotic for two years? If that is the case, you need to know that mac patients cannot be totally drug free. We need to be on lose dose maintenance meds to keep the mac away. The circumstances that allowed you to get mac in the first place, do not go away with antibiotics. This is what my Mayo dr explained to me. The preventative maintenance meds have kept me mac free since 2014.
