i’m not with kaiser but my parents are and some doctor they like and others they don’t. They simply request another Dr. until they find one they are happy with. Don’t be afraid to ask for another pulmonologist. We are in the Los Angeles area but the same policy should apply. I would learn all you can so that you can ask all the questions you need. I also was diagnosed with MAC in 2009. I also could not handle rimfampin so i only took the other 2 (cyrithermyacin and ethembutol) I have been negative to MAC for 1.5 yrs so I’ve been taken off all antibiotics. it’s been a month so far and I feel fine, except I have bronchietasis. This is a long process but your husband will get through it and learn to manage the broncheitasis. Make sure he gets a flu, and pnemonia shot, try and avoid catching colds, don’t wear yourself out, take immune boosting vitamins. Ask for CT scan at least 1 a yr.
