My daughter suffers from asthma and has been taking medication for her condition for almost five years now. She will be 14 next month, and her asthma seems to have been improving lately but I want to keep it that way too. I heard about a drug called xolair, that is supposed to be the best asthma med out there. What can you guys tell me about xolair? And are there any side effects? Is xolair suitable for adolescents?
