I do colistyn every other month and had the results you describe only with TOBI. I actually find colistyn helps me cough a ton of stuff up, which I don't think its supposed to do cause its an antibiotic, but I think the "foaming" actually helps loosen things up for me so I do feel better on months I'm on it. I don't get tight at all with coli, but got progressively tighter and worse when I was on TOBI over a couple of years.
Oh, and isn't generic, by law, supposed to be the "equaivalant" to name brand? I also used X-Gen, but have used the brand the base gave out a couple years ago and couldn't tell a difference. I was under the understanding that generic, in order to be substituted, has to be a nearly identical formula.
I know this isn't the case with enzymes, however, which must be name brand cause if they're not, that could cause problems. That is the ONLY name brand med I take (besides pulmo since there is no generic). Everything else from Azithro. to albuterol I take generic when possible.
