@pejohnston , Hello, and welcome to the Connect community. Do you have a a first name that you would like to use? To answer your question about long term antibiotics; you will see that many of our members are on a long term regimine. Most that are taking antibiotics are taking the 'Big 3' cocktail. People usually are on them anywhere from 18 months to 3 years. I am on a different kind of ongoing regimine. I have been taking alternating singular antibiotics on alternating months. I have been doing this since 2013. It is known as a prophylactic approach. My doctor explained that he liked this approach because it is more tolerable for the organs and prevents the mac from becoming resistant to the antibiotics.
