Thanks for all the replies. I hate to not use it, at one time it was really good for me and I improved so much when I was on it. I too mix mine for each dose with sterile water, I use 4cc of water. Jennifer, that is interesting that you also had trouble with it after you used Tobi. Coly doesn't make me cough more, just feel tight and short of breath all day. I am going to talk to my Doctor about this, see what he says. I am getting a CT scan of the ol' lungs thursday, trying to find out what is going on down there. My CF doctor didn't mention any other options in place of coly-mycin. I don't know that there are any options.
