So it begins. I have been silently watching so many posts and replies from this site over the past six months. I am finally here to post my first question as I am still processing what happened today at school. Today marks the first day my five year old in junior kindergarten was sent to the principals office and I got the dreaded phone call. We have been struggling with self control and aggressive behavior with other children, mostly in the school environment. My son was diagnosed with ADHD one year ago and has been taking methylphenidate for almost one year. At first I saw positive improvement with behavioral and focus. Over the past few months I have steadily seeing a decline in behavior and the medication does not seem to be working at all. We have tried short acting, extended release, different dosage etc. I just scheduled an appointment with the pediatrician tomorrow. Thinking of changing to a different medication that might work better. Anyone out there had good then bad results with methylphenidate and have any suggestions as to what we should try next. I do understand everyone reacts differently to all medications. Just looking for experiences. I should also note we have a meeting scheduled with the school social worker and school psychiatrist this week as well. I know there are so many of you out there that Have done this roller coaster ride but it’s really starting to take an emotional toll on me and our family. I appreciate any insight.
