I've been using the adult Pulmicort for about two years, and have had no side effects. Can't say that with Advair. I had to discontinue that. May I make a suggestion? I've gotten good benefits from breathing exercises, specifically those outlined by Paul Sorvino in his book, "How to Become A Former Asthmatic". If you look up the Sorvino Asthma Foundation online, there is good info for children with Asthma, and information about a video of the exercises, meant for children. Can't hurt. Maybe it can help him cut down on some of his meds. Good luck. :)
