My 9 year old son was diagnosed with add a year ago. he was moved up to 70mg adderall (dextroamphetamine and racemic amphetamine) xr dose this week. is this too high for 52" 65lb child?

Adderall (dextroamphetamine and racemic amphetamine) dose: Your son's dose seems high. However, determining the best Adderall (dextroamphetamine and racemic amphetamine) dose should weigh benefits, eg, improved focus, concentration, less impulsive vs. side effects, eg, dazed looking, insomnia, no appetite, weight loss, etc. Suggest you ask prescribing doc if a lower dose can be tried. I hope this helps. Best wishes.
