Adult Methylphenidate Extended-Release Dosing Guidelines

Initial Dosing Strategy

The American Academy of Child and Adolescent Psychiatry recommends starting with 18 mg once daily for extended-release formulations like Concerta, taken in the morning 2
For immediate-release methylphenidate converted to ER, 18 mg Concerta is approximately equivalent to 5 mg immediate-release three times daily 2
Lower starting doses may be appropriate for patients more sensitive to stimulant effects, though specific adult guidance for this is limited 1

Increase dose weekly by 18 mg increments based on symptom response and side effect profile 1
The maximum recommended dose is 72 mg daily for extended-release formulations, though some guidelines cite 60 mg as the upper limit across all methylphenidate formulations 3, 1

Check blood pressure, pulse, height, and weight at baseline before initiating treatment 3, 1
Monitor cardiovascular parameters regularly, with adults having blood pressure and pulse checked quarterly during treatment, as methylphenidate can cause modest increases 3
Assess for common side effects including insomnia, decreased appetite, anxiety, agitation, tachycardia, and palpitations, particularly during the first few days and weeks of treatment 1, 4

Use standardized rating scales to assess ADHD symptom improvement before each dose increase 1

Administer methylphenidate in the morning to minimize insomnia risk, as effects last 12 hours with OROS formulations 1, 2
Avoid methylphenidate in patients with uncontrolled hypertension, underlying coronary artery disease, tachyarrhythmias, or use of MAO inhibitors within 14 days 1, 4
