@elainet Not being on an antibiotic long enough is a common mistake that some doctors make. Been there, done that myself. People with bronchiectasis need to be on maintenance antibiotics if they are in the phase of the disease where mac and pseudomonas infections are starting. When I was diagnosed with mac in 2005, I was put on a ten day run of cipro, that's it. That was a temporary fix. Then, they put me on zythromycin for ten days. I was less sick, but still sick. I got sicker and sicker until I went to the Mayo Clinic finally in 2013. I was put on light, but steady monthly antibiotics for three years. It got rid of the mac. Then, I got pseudomonas in 2016, was put on tobramycin every other month, cipro on the other months. I am still on that regimen and doing great. The bottom line is, you may need to be on lifelong antibiotics if your bronchiectasis is bad enough. Many people on this forum are catching theirs early and slowing the progression of the disease.
