Hello Kay. Yes! You should have a nebulizer and get a prescription for 7% sodium chloride. Most drs say to do a nebulized treatment twice a day. It keeps your lungs clear of phlegm, which we know is a breeding ground for mac and other organisms. It also helps to limit mac growth and lesson the awful symptoms of mac infection. A phone call to your dr's office to ask for a prescription should suffice. If you have trouble getting your dr to prescribe it, be sure to ask 'Why?". There is a print-out of a study by NIH that proves that 7% saline is very helpful in managing this disease. In some cases, the 7% saline has shown to eliminate mac. In all of my years on this site, I have seen how many of us on here have improved substantially by using the 7% saline. Will you please get back to me and let me know what your dr says about it?
