That is what I am assuming. It seems pretty obvious to me. Standard allergy meds weren't helping and he was on constant neb treatments and steroids 5 times in 2.5 months. After starting Advair he has only had one round of steroids and three weeks of neb treatments because of the flu. That is a HUGE difference just adding one medication. He has always been on singulair but that only helped a little. We'll just wait and see. Like you said, they don't really mean anything different I just get wierd looks from people when I say RAD and then explain that it is the same, just a different name. I used to say baby asthma because that is what they told me when he was 3 months old after he got croup but he isn't exactly a baby anymore.
