Maximum Aripiprazole Dosage for Symptomatic Patients
For symptomatic patients, the maximum recommended dose of aripiprazole is 30 mg/day for oral formulations, with 10-15 mg/day as the typical starting and target dose. 1, 2
Oral Aripiprazole Dosing
The recommended starting and target dose is 10-15 mg/day administered once daily without regard to meals. 1
Aripiprazole has been systematically evaluated and shown to be effective in a dose range of 10-30 mg/day, with 30 mg/day representing the maximum recommended dose. 1
Dosage increases should not be made before 2 weeks of continuous therapy, as this is the time needed to achieve steady state. 1
At least 1-2 weeks, and sometimes up to 4 weeks, may pass before aripiprazole reaches its full effect. 1
Dose-Response Considerations
The optimum dose for aripiprazole appears to be 10 mg/day, with the highest response rates observed at this dose. 2
Doses above 20 mg/day do not appear to provide additional benefit and may be associated with smaller changes in symptom scores. 2
The threshold for clinical effect is between 5-10 mg/day, with near maximal dopamine D2 receptor occupancy achieved at 30 mg/day. 2
Long-Acting Injectable Formulations
For patients requiring long-acting injectable therapy:
Aripiprazole once-monthly (AOM) 400 mg is the standard starting and maintenance dose for the injectable suspension. 3
Aripiprazole lauroxil (AL) 1064 mg can be administered every 2 months (every 8 weeks) for maintenance treatment. 4, 5
When initiating AOM 400, concomitant oral aripiprazole (10-15 mg/day) or continuation of previous antipsychotic for ≤14 days is recommended to ensure therapeutic concentrations. 3
Critical Pitfalls to Avoid
Do not increase doses before 2 weeks of therapy, as steady-state concentrations are not attained until 14 days of dosing. 1
Avoid exceeding 30 mg/day for oral formulations, as higher doses provide no additional therapeutic benefit and may worsen outcomes. 1, 2
Do not expect immediate therapeutic response; allow 1-4 weeks for full clinical effect even after reaching steady state. 1
