Thanks you son much for your response. Yes, I am taking Rifampin, Ethambotol, Azithromycin, and waiting on a trainer to show me how to use the Arikayce as it is inhaled. I have also been on Predisone and Bactrim for 2+years. I also take oxybutin for incontinence, vitamin D, Benzonatate for cough, clotrimazole due to thrush and Pantoprazole to help with stomach issues. So many meds I take the MAC meds in the AM and the others in the PM. The Arikayce starts this week and I am to use my Albuterol 30 min prior.
