I had a constant cough and after 14 days on Cipro the cough is gone (has been for 2 1/2 months). I am currently taking the big 3 for MAC and will do another sputum culture after the first of the year. I will ask them to retest for pseudomonas at the same time. These bacteria are so hard to kill that I won’t be surprised to find it has returned. The MAC hit me very hard in May and I am now starting on my third month of the big 3. I’m just beginning to feel energy coming back but still a long way to go.
