Hi, I am new to the forums, my daughter, diagnosed with Cf fall of 07, recently cultured pseudo. Dr. kept her in hospital 15 days iv tobi and cephtazidine?, now home for inhaled tobi, the cough that had been associated with the pnemonia in her lungs had cleared up after a couple days on iv antis a hospital, but have noticed after a week on the inhaled tobi that she has started coughing again, dr. listened to her breathing, thought she sounded a little congested, figured it might just be the mucus loosening up in her chest, but didn't seem overly concerned, any other reasons for increased cough while on tobi. My daughter will be four in March.
