I thought it might be interesting and helpful for those of us posting on this website to share what each of our CF kids, or those that have CF, grow in their cultures. It will help those thinking of starting GSH to know how GSH is helping and also give us a baseline. My daughter is 11-years-old and currently cultures seveal strains of non-mucoid PA. She began culturing PA when she 6-years-old, shortly after starting oral GSH. We were hoping the GSH would clear it but it didn't. She inhales Tobi every other month and this works to keep it at bay. Would love to hear from others as well. Hope this helps. Oh, we give her inhaled GSH twice a day (200 mg. each session mixed with hypertonic) and there have been no side effects that we are aware of.
