Please,please, please. Check the diagnosis first before increasing or changing meds. If you have the wrong diagnosis, meds work at first then they don’t. Most doctors just assume it’s the medication not an incorrect diagnosis. A mental health Professional should be making a DSM diagnosis. ADHD can also mirror depression and or anxiety. Just medication does not work alone. there is no magic pill. Consulting with a behavioral therapist is paramount to dealing with the issues. The end game is the child being able to make adjustments in behavior. New skills and coping strategies need to be taught, which begins with adults changing behavior and child responding to that change. Good Luck!
