Focalin (Dexmethylphenidate) Dosing Recommendations

The maximum total daily dose of immediate-release Focalin is 40 mg per day, administered in divided doses throughout the day, as recommended by the American Academy of Child and Adolescent Psychiatry. 1

Dosing Strategy

Immediate-Release Formulation

  • Maximum daily dose: 40 mg total per day for patients taking multiple daily doses 1
  • The medication should be divided into multiple doses throughout the day (typically 2-3 times daily) 1
  • Dosing should be carefully titrated based on individual response and tolerability 1

Extended-Release Formulation

  • The 40 mg maximum applies specifically to immediate-release formulations, NOT extended-release products 1
  • Extended-release formulations have different dosing parameters and should not be assumed to follow the same maximum dose guidelines 1
  • Lack of safety and efficacy data beyond recommended doses necessitates careful consideration when prescribing 1

When Treatment Fails

If no improvement occurs after appropriate dosage adjustment over one month, switch to an alternative stimulant or add non-pharmacological interventions. 1

Treatment Modification Algorithm

  • Allow adequate trial period: one full month at optimized dose 1
  • If inadequate response: consider switching to a different stimulant medication class 1
  • Alternative approach: augment with behavioral interventions or other non-pharmacological strategies 1

Critical Caveats

  • Do not exceed 40 mg/day for immediate-release formulations without clear evidence supporting higher doses 1
  • The absence of safety data beyond recommended doses means exceeding these limits places patients at unknown risk 1
  • Extended-release formulations require separate dosing considerations and should not be dosed using immediate-release guidelines 1
