I was on the big 3 for 2 1/2 years, but after 1 year was taken off Ethambutol because of eye problems. I was then put on Arycase for 1 year but my cough kept getting worse so I was taken off it. I had my last CT scan about 6 mos ago and it was much better, in fact I was taken off all antibiotics. So far I have beat MAC and at 77 years old I feel I am very lucky. However I did suffer from MAC for 7 years before it was diagnosed, loosing 100 lbs.

Good luck to you and don't get discouraged it can get better. Just remember everyone is different. It may take longer for some and some antibiotics work good for some and not for others. Hang in There!
