@kaykuz Did the ID doc tell you why the recommendation is for daily? Usually I believe that is reserved for cavitary MAC, aggressive strains, or MAC that doesn't respond to 3X weekly treatment.

In 2019, when I was switched from 3 x weekly to daily, it was because my lung nodules were still getting larger, they were afraid it was going to become cavitary, and I had been on the lower dose for over a year without results. Within 6 months, the nodules shrunk, even though my cultures were still positive, but I was having extreme difficulty with nausea, fatigue & weight loss. At that point we stopped the antibiotics, but continued airway clearance with 7% saline. My lung CT's have remained stable (due for another in October to confirm.)
