Dose Titration: Dosage should be individualized according to the needs and responses of the patient. Doses may be increased in 18-mg increments at weekly intervals. Daily dosages >54 mg in children, 72 mg in adolescents and 108 mg in adults have not been studied and are not recommended.
Maintenance/Extended Treatment: The long-term use of methylphenidate has not been systematically evaluated in controlled trials. The physician who elects to use Concerta for extended periods in patients with ADHD should periodically re-evaluate the long-term usefulness of the drug for the individual patient with trials off medication to assess the patient's functioning without pharmacotherapy.
Dose Reduction and Discontinuation: If paradoxical aggravation of symptoms or other adverse reactions occur, the dosage should be reduced, or if necessary, Concerta should be discontinued.
Children: Use of Concerta in patients <6 years has not been studied in controlled trials. Concerta should not be used in patients <6 years.
