@cpitts I have not had any bad reactions from the ethambutol or the Clofazimine. A slight skin darkening (tan) from Clofazimine but not very noticeable. Has your doctor mentioned adding Arikayce? It hasn't worked for me so far but there are many others on this group who have had their sputum cultures convert to negative within just a few months on of starting it. Thanks for the prayers!!
