Because TOBI made me short of breath (SOB), I discontinued use of it & could tell a huge difference after I quit.
I was on it for about 2-3 years before I had SOB from it. I started to notice a pattern of the shortness of breath being worse when I was on the "on" month of TOBI.
If you do do TOBI one month on, one month off, try to see if you notice a difference in the SOB during the month when you're not doing the TOBI.
We all react to things differently, hopefully, if you're on TOBI, it's not causing the SOB, because I think it is a good medication, it just doesn't work for me.
I hope you get to feeling better
