Adderall Starting Dose and Titration Guidelines

Age‑Specific Starting Doses

The American Academy of Child and Adolescent Psychiatry recommends initiating treatment in children ≥ 6 years with 2.5 mg twice daily (morning and noon), adjusting later based on response. 1
An alternative approach for the same age group is to start with 2.5 mg once daily in the early morning and add a noon dose only if the duration of effect is insufficient. 5
For adults and older adolescents, the guideline advises a starting dose of 5 mg once or twice daily, with titration thereafter. 9

In children, increase the total daily dose by 2.5–5 mg each week until optimal symptom control is achieved or side effects appear. 1
In adults, increase the total daily dose by 5–10 mg each week following the same criteria. 9
The maximum recommended total daily dose is 40 mg for both children and adults; some adults may require up to 0.9 mg/kg but should not exceed 40 mg. 1

Immediate‑release Adderall formulations typically require 2–3 daily administrations because of their short duration of action. 1
Doses should be given after meals (breakfast and lunch) when feasible to minimize gastrointestinal irritation. 1

Follow a standard stepwise titration: weekly dose increases of 2.5–5 mg for children or 5–10 mg for adults until symptoms are controlled or adverse effects emerge. 1
Prior to each dose increase, obtain rating scales from parents/teachers (children) or the patient/significant other (adults) to objectively assess response. 5

In a forced‑titration protocol, the patient receives all four dosage levels (2.5, 5, 7.5, 10 mg for children; 5, 10, 15, 20 mg for adults), each lasting one week. 9
After the trial, the clinician selects the dose that provides the greatest benefit with the fewest side effects. 9

Children weighing < 25 kg should not receive single doses > 10 mg of amphetamine. 1
For children weighing < 20 kg, the 7.5 mg dose week should be omitted during titration. 9

Obtain baseline vital signs, height, and weight as part of the physical examination prior to starting Adderall. 1
In adults, blood pressure and pulse should be checked quarterly throughout treatment. 1

Maintain weekly contact (office visit or telephone) with the patient during the dose‑adjustment phase. 8
Systematically assess for insomnia, anorexia, headaches, social withdrawal, tics, and weight loss at each contact. 2
The titration phase usually lasts 2–4 weeks; once a stable dose is reached, schedule monthly follow‑up visits until symptoms remain stable. 8

Amphetamines are associated with greater appetite suppression and sleep disturbances compared with methylphenidate, likely due to longer half‑life. 1
If the maximum recommended dose does not achieve adequate control, clinicians should consider switching to another medication or adding psychosocial interventions rather than exceeding the dose ceiling. 1
