Attention-deficit/hyperactivity disorder (ADHD) is a common neurobiological condition affecting 5-8 percent of school age children,with symptoms persisting into adulthood in as many as 60 percent of cases (i.e. approximately 4% of adults). Appreciation of this fact has markedly increased the number of adults with take medication for ADHD, such as Ritalin or Adderall. Among other controversies in this field, is the dose of Ritalin. Prescribing information says:”Administer in divided doses 2 or 3 times daily, preferably 30 to 45 minutes before meals. Average dosage is 20 to 30 mg daily. Some patients may require 40 to 60 mg daily. In others, 10 to 15 mg daily will be adequate.”
