I have gotten the 7%...it is on Amazon and maybe also on ebay. Had to buy it on my own as my pulmonologist said he did not want to prescribe it last time I went as he said it can cause bronchospasm. I have had no problem with it and plan to ask him again when have my return appointment. I can get it cheaper with a prescription. Thank goodness found out about it on this forum. I do have a question....when everyone nebulizes twice a day, how long in between do you wait? I used to do morning and evening but at this busy time I sometimes do the second one in the afternoon and feel like getting it in then is better than missing a second all together.
