Hi my 2 yo with CF has just recently been diagnosied with MRSA in addition to Pseudomonas. We are currently doing Cipro/ Tobi (3 weeks on/2 weeks off), and Bactrim ( 2weeks). I find lots on the internet about Silver treating MRSA on the skin but not alot about CF and MRSA in the lungs. I also needed to knwo the doseage. Thanks and if anyone has anything they do to beat it or prevent it PLEASE share!!!
