My PFT's are down about 6-7% from last month with little to no symptoms. Both of my CF docs at 2 different centers tend to be conservative and start with an oral antibiotic and an inhaled antibiotic and check PFT's again in a couple of weeks. Is that the smart way to do things? I am having very few symptoms and just came off of IV's about 2 months ago. It is also that time of month and it is raining today. BTW, I am starting Levoquin 750mg and continuning inhaled Tobi. I appreciate your input.
