Wow, I never would have thought of milk protein being in asthma meds (Advair). I've never used Advair. I knew to look out for vitamins but hadn't even thought of that. I use aerosol meds--Flovent is good if you need a daily inhaler. I've used several others if you want to talk about meds later. Otherwise ask your doc. Good luck and good job on being an informed consumer!
