K.M.
My son was diagnosed with cough variant asthma also and have had absolutely no luck with getting it under control. I don't think the doctors know what my son really has and since he happens to have a cough sometimes they put that label on him. At one point, we had my son on 6 different meds two-three times a day. We have since taken him off everything and have taken him to a new doctor because with or without the meds he still has his croupy, barky cough. My only advice is to not let the doctors tell you something that you know instinctually is not right. If they put him on meds and he's doing well, that's wonderful. But we've been doing this for almost 2 years now, and they keep telling us the meds will work eventually. I'm not buying it!!! Good luck and keep everyone posted.
