I wrote some time ago that my pulmonologist was ok with me nebulizing cromolyn sodium instead of Budesonide which is a steroid. It used to be used for mild to moderate asthma and it’s an anti inflammatory. Since steroids are so effective they are prescribed. Cromolyn is an older type of medication not much popular any more. It works except that you have to nebulize 4 times a day. Ask your pulmo about it.
