I have a daughter who is 9 years old and she was diagnosed with ADHD when she was 6. she has been taking Concerta since her diagnosis with gradual changes is mg. her behavior lately (last 6 months) has worsened and she has become more impuslive. she was a straight A student 1st 2nd grade and the first half of 3rd grade. the child is very intelligent. however she is becoming increasingly more distractable. her doctor wants to change her medicine and put her on Focalin. can anyone tell me if they have had any success with this one or should we try something else. thank you for listening
