When I was diagnosed with MAC a year and half ago, my pulmonologist recommended nebulizing with albuterol AND then 7% saline twice a day. It was not an either/or. Friends in a support group suggested waiting 10 minutes after the albuterol to do the saline. I’ve had the same effects as you (jittery, etc) from albuterol and stopped using it in the evening as sometimes I was too jazzed up to sleep. She didn’t like this and then prescribed levalbuteral with is a little better but I still don’t use late in the evening but always use the saline twice a day. Albuterol opens up the airways but saline thins the mucus to help get it out. Some also say the saline makes it hard for the MAC to flourish.
