Our daughter has had very little if any lung issues. But her Doctors has had her on HS for over a year, she started it right after the New England Journal of Med. published it's findings in the clinical trials. She has been on the full dosage, and the only problem she had was getting use to the concentration of the saline getting into her lungs. After a few times, she got use to it, like all the other meds.
Avery was the youngest to be put on it at the time and we have nothing but great things to say about it. If they are offering to put your child on it, then I would stand by that b/c Avery has had no problems. She is at this point not a cougher, she was not been sick in at least a year. She does it twice a day, and right now she is only on the HS and not Pulmozyme,but she normally does the two. Hope this helps !!
