I am 79 and have a lung fungi, a newer one called apiotrichum mycotoxinivorans. I am not on any medications for MAC/BE after experiencing major side effects from 2 of the 3 Big 3 drugs. I am on no med for the fungus, at this point anyway, in spite of knowing of its existence for a year now. I use only the Aerobika for airway clearance. Adding the saline/albuterol or any combination of those causes hemoptysis episodes, including, occasionally, the use of the Aerobika by itself. I consult with my ID doctor soon and treatment may change after he views my next CT scan and other tests ordered at that time -- but hopefully no changes for me.
