This is a question have been struggling with for a long time. I have even posted here and the adult board about it, so if you search for Pulmozyme, you may find my previous post and some more answers.
My daughter, Hayley, is 2 years old and is NOT on pulmozyme. I know a lot of kids and infants are, but most of them just because their doctor or clinic puts everyone on it. I cannot find any studies or proof that they can actually show that it does help, have better PTF's or FEV1.
I have asked our doctor about it (I LOVE our doctor and trust him implicitly!) He said there is no proof that it helps and that Hayley is not sick enough to need it (She has been hospitalized 3 times, on IV antibiotics twice, had Nissen Fundoplication) He however, is interested in Hypertonic Saline, and may prescribe it soon.
My thinking at this point is that we are not going to do Pulmozyme at his point because:
1) There is no definitive proof that it helps.
2) I don't want to add ANOTHER treatment if we don't need it.
3) It is so expensive! About $1,500 per month!
4) Some people have had lung bleeds while using it.
If anyone has access to any studies on pulmozyme I would love to read them!
