i forgot to mention that with as many problems as i have with hemoptysis ( i've had 3 embolizations already, due to it) Pulmozyme doesnt seem to be the root of it. When i was first hospitalized for a bad bleed they had me doing the Pulmozyme twice a day ( i normally do it once a day) to get any extra mucus out, and surprisingly no bleeding with it ( Thank GOD).
