I am curious how you all feel about tune-ups. I am kind of new to the IV antibiotic world. I have only had them 2x. I know some centers recommend tune-ups on a regular basis regardless of numbers. I am at a relatively low FEV1 but stable and feeling good. It has been about 6 months since I was on IV's for a minor infection. I discussed it at my last CF visit. He would not have brought it up had I not. He said he thinks it is reasonable to consider and would leave the choice up to me. So at the end of January, we may do a tune up if I desire. I would like all your thoughts on this and also suggestions for good "drugs". I have only been on Tobra with Merepenim and also Ceptazadyme. I know I butchered those spellings. I regularly culture 2 or 3 strains of pseudomonas aruginosa. Thanks for any advice.
