hey, i'm almost 17 w/cf and i am hardly ever sick. i was only in the hospital one time and that was when i was a baby and diagnosed. my brother, who also has cf, was sick and they tested him for it, so they just decided to test me. well anyways, i have had pnewmonia a few times and i get bronchitis about 1 time a year. My doc just puts me on antibiotics and i always get better. well not this time. i was put on leviquin for about 2 weeks and i didn't get better at all, but we never bothered to tell the doc about it untill we went back 3 months later. i was then put on a very high dosage of cipro. cipro has always worked great for me, but it so far hasn't this time. i have been on it for 2 1/2 weeks and i get off in about 3 days. in fact i'm getting sicker. my pft's was low when i went to the doc last, but they said that was because i was sick. i had to start doing flonase and i use to only take albuterol 1 time a day, but i now take it 3 times day. i haven't gotten any better and i'm scared that my health is going to start declining.
