I am on Medicare also and about to start arikayce. The nurse called to tell me my co-pay would be $2000. a month! That’s after my insurance, Aetna, approved $139,000. for a year. She’s sending papers for me to fill out to see if there are any grants available. In the meantime I’ve been on the big three plus albuterol in nebulizer and vest. I guess we’ll see what happens...
