@sueinmn I was diagnosed with MAC after a bronchoscopy tested positive. Then my Pulmonologist referred me to ID doctor for treatment on Dec of 2024. The ID doc did not want to prescribe the Big 3 for me and delayed prescribing until I became very adamant to start treatment. These doctors are all at Mayo in AZ. I have been on Big 3 antibiotics for 6 months and doing much better but have cultures of sputum still showing abnormal. Even at Mayo there seems to be a disconnect on which department is supposed to start treatment for Mac. When I grew a backbone and demanded treatment 7 months after the lab diagnosed MAC the ID doc said that she hears this complaint all the time about delayed and stalled treatment start. Very frustrating for the patient .
