I haven't discontinued Pulmo since being on HTS. The order I go in is duoneb, pulmozyme, HTS, and then Tobi/Colistin. Definitely the last thing you want in your lungs in the antibiotic! Also, my doc says to do Duoneb, Pulmo, and HTS all while doing CPT.
You do Pulmicort nebulizer? I'm on the inhaler so I'm wondering what your thoughts are of the neb version.
