I finally received my Rx for the 7%. Based on the way my Dr wrote the Rx, (3x per day, I only neb once per day), I received 270 vials !! LOL. I’m happy about that, since then I have to reorder less frequently. I guess that’s why it cost $94. Going to try it later today. I’m a little concerned that it might cause hemoptysis. Anyone have any thoughts or experiences with this happening?
