I wanted to post this b/c I know there are a lot of articles about reactions like shortness of breath and wheezing when people initially take nebulized Glutathione. I initially got these reactions when I took nebulized glutathione for the first time, but then I spoke with someone at InHome Rx (a pharmacy in california who makes up vials of nebulized Glutathione) and they told me to take asthma medication with it for the first ten days. I did that and I didn't get the wheezing. Hope this helps.
