My son started with Focalin, which helped drastically reduce his impulsivity, but it made him incredibly irritable. So then we added Intuniv and it helped his irritable behavior and he seemed happier. Then he started developing extreme anxiety, no one is exactly sure why. So after trying talk therapy, we decided to add Prozac and it has made such a difference in his anxiety, happiness and impulsivity that we may be getting rid of the Focalin and just keep him on the Intuniv and Prozac for awhile. We think his significant problems may have been caused by anxiety and not adhd. My point here, is, we do not always know what we think we know and since the child brain is such a mystery trying things could lead you down a more successful path. Maybe all along our sons problem was dopamine production and not the brain chemical focalin works on. More drugs sucks, but with the goal of a happy, well adjusted child, it could be the best solution.
