Flovent and aggression

My three year old son has been on Flovent since he was two, he has been showing signs of restlessness, aggression, sleeplessness and other behavior problems, I did not think anything was wrong until I looked up the effects and saw they were listed as a reason to stop taking the medication. I have been doing my own trial and error research with him. He has been off Flovent for two weeks and I have not seen a difference in his behavior, luckily his asthma was ok, which leaves me to believe that it is the Singular pill that is the problem. I will post an update in two more weeks under the Singular side effects.
