It's been a while, but I had two rounds of inhaled Tobramycin and lost most of my voice. It recovered after about 3 weeks or so, but now I am much more sensitive to any irritation of throat/vocal cords (after over 3 years.)

The second piece, bronchospasm, is indeed very scary - I have experienced a few times, but knew what it was because a daughter has had it. Mine came from a specific inhaler, and the longer I used it, the more often it happened, so my pulmo changed me to another med. The opinion was that I had become sensitized to one of the propellants.
