My son is 4 years old and has been on Advair 100/50 for 3 weeks. He has chronic bronchitis and since the Dr has put him on Advair we have noticed a change in his behavior. He cannot sit still and is wired ALL the time. His pre-school teacher said he is being very disruptive in class. He has trouble sleeping at night and he has a runny nose all the time. He has been telling me that his legs hurt him and his stomach hurts all the time. I assumed the legs hurting was due to him "growing". Boy was I dumb. I now believe it is linked to this medicine! Has anyone ever stopped taking this medicine "cold turkey?"
