I am also on either Arikayce (amikatcin) or placebo, Azithromycin and Ethambutol (Encore Arikayce study). I am using florastor probiotics - recommended by my gi doc. Only (or one of very few) probiotics established thru clinical studies to help keep intestinal flora in shape with antibiotic treatment.
I also had only mild bronchiectasis and MAC symptoms and while I'm tolerating treatment well physically so far, it is super time- and energy-consuming so in that sense the treatment is more overwhelming than the disease but I definitely want to treat before it progresses and not after! Any of us of a certain age or having other immune etc conditions are at high risk for progression and worse permanent damage.
Anyone just starting on this road and in shock: give yourself time, you will sort out what works best for you to have quality of life vs disease dominating everything!
This group is a tremendous help!
