Hi Julie,
I believe that DNASE is actually Pulmozyme...Pulmozyme is the brand name of the drug. If I'm wrong here, someone please correct me but I do believe they are the same thing. (Unless there's a new drug using that name that I am not aware of) ... You can search under Pulmozyme or Genentech (the company who makes it) online and should find plenty of info. I copied this from Genentech's website:
"Pulmozyme Inhalation Solution is a sterile, clear, colorless, highly purified solution of recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. Pulmozyme is administered by inhalation of an aerosol mist produced by a compressed air driven nebulizer system."
It's more of a preventive drug, not one to treat infections. It helps break up mucus to prevent infections. It needs to be taken daily to work to prevent problems. I have heard wonderful things but can't really say anything personally. One of my daughters has been on it for 6 years and is still on it daily, but my other daughter is not on it and never has been. I can't really say there is any difference in their disease. They are both extremely healthy so it's hard for me to say if the pulmozyme makes any difference or not.
Hope this helps a little. Again, anyone please feel free to correct me if there is another drug I am not aware of. I'd be thrilled to have that info also...
