Recommended Treatment for ADHD
For ADHD treatment, methylphenidate (MPH) should be prescribed as first-line pharmacological therapy, combined with evidence-based behavioral therapy, particularly for school-aged children (6-11 years). 1
Age-Specific Treatment Recommendations
Preschool Children (4-5 years)
- First-line: Evidence-based parent/teacher-administered behavior therapy
- Second-line: Methylphenidate may be prescribed if behavioral interventions don't provide significant improvement and moderate-to-severe functional impairment persists 1
- Starting dose: Lower than school-aged children with careful monitoring
School-Aged Children (6-11 years)
- First-line: FDA-approved medications for ADHD (strongest evidence for stimulants) AND evidence-based behavioral therapy 1
- Medication options in order of evidence strength:
- Stimulants (methylphenidate)
- Atomoxetine
- Extended-release guanfacine
- Extended-release clonidine 1
Adolescents (12-18 years)
- First-line: FDA-approved medications with adolescent assent
- Behavioral therapy may be added 1
Medication Specifics
Methylphenidate (First-line)
- Dosing for children <70kg: Start at 0.5 mg/kg/day, increase after 3 days to target dose of 1.2 mg/kg/day 2
- Dosing for children >70kg and adults: Start at 40mg/day, increase to 80mg/day after 3 days 2
- Available formulations:
- Immediate-release (IR): Effects last ~4 hours
- Extended-release (ER): Effects last 8-12 hours 2
- Titrate to maximum benefit with minimum side effects 1
- Common side effects: Appetite suppression, insomnia 2
Atomoxetine (Second-line)
- Dosing for children <70kg: Start at 0.5 mg/kg/day, increase after 3 days to target dose of 1.2 mg/kg/day 3
- Dosing for children >70kg and adults: Start at 40mg/day, increase to 80mg/day after 3 days 3
- May be taken with or without food, as a single daily dose or divided doses 3
- Preferred for patients with:
Guanfacine Extended-Release (Third-line)
- Starting dose: 1 mg daily 4
- May cause somnolence, fatigue, hypotension, and bradycardia 4
- Beneficial for patients with hypertension due to blood pressure-lowering effects 4
Regional Variations in Treatment Guidelines
According to 2024 Asian guidelines 1, methylphenidate is recommended as first-line treatment across most Asian countries:
- Japan: OROS-MPH, atomoxetine, or guanfacine ER as first-line
- Malaysia: MPH-IR and MPH-ER available, maximum dose 60-72mg/day
- Singapore: MPH recommended as first-line
- India: Stimulants first-line for severe symptoms, with MPH, atomoxetine, and clonidine approved
Monitoring and Follow-up
- Titrate medication doses to achieve maximum benefit with minimum adverse effects 1
- Regular monitoring of:
- Vital signs (especially with guanfacine)
- Weight (especially with stimulants)
- Psychiatric symptoms (especially with atomoxetine - monitor for suicidal ideation) 4
- Recognize ADHD as a chronic condition requiring ongoing management 1
- Periodically reevaluate the long-term usefulness of medication 3
Important Considerations
- Screen for bipolar disorder before starting atomoxetine 3
- Adjust dosing for hepatic impairment and CYP2D6 poor metabolizers 3
- Methylphenidate has a rapid onset of action (1-3 hours) but short duration with IR formulation 2
- Individual response variability is high; dose optimization improves outcomes 5
- Recent evidence suggests methylphenidate may improve teacher-rated ADHD symptoms but may increase non-serious adverse events 6
ADHD treatment should be considered part of a comprehensive program that may include psychological, educational, and social interventions tailored to the individual's needs 3.
