He has sensitive staph, and had cultured PA years ago, but hasn't in a long time. But he has been on Tobi for years, not super compliant with it, so I think his docs figured Cayston would be easier, i don't boil his nebs very often, but I soak them as soon as he is done...I didn't know it came w a sterilizer, I wonder if it will depending what pharmacy it comes from, some of his meds come from caremark, some come from cff pharm... I heard it helps w lung functions, his PFTs have been holding steady at 98 for the last year (since being hospitalized last fall they were at 107 on all the crazy antibiotics in the hospital), I think he has lucked out with less lung complications, mostly digestive issues...Seems like everybody else in the house goes through colds and bronchitis and they never even touch him...
