@grannylu I was concerned about the antibiotics also but I did my research and feel comfortable with my ID doctor as he definitely has experience treating MAC. I had my baseline hearing and vision test done. He will be regularly monitoring both along with blood work so I feel comfortable that if something starts to go wrong we will catch it before too much damage is done. I have multiple cavities, one measuring 11cm. I believe this is because I have had this disease for a long time before it was caught. I have now seen the damage it can cause and understand how important it is to try to eradicate it before further damage is done. As long as you are monitored closely and do your best to adhere to the guidelines, my humble opinion is that not treating is more of a risk than treating.
