I use Breyna - a generic version of Symbicort. Yes, it contains a low dose inhaled corticosteroid (ICS); it also contains formoterol, a long-acting beta-agonist (LABA). While steroids are usually not recommended for people at risk for MAC, my pulmonologist and I decided my need to breathe outweighed the slightly increased infection risk.
This was a gam-changer for me, because lifelong asthma had me feeling "air starved" most of the time, and was causing a feeling of pressure in my chest.
I have been on it for over 1 1/2 years, and recently had my very first exacerbation since starting, caused by a cold. I managed to get through it without antibiotics.
