Prescribing Age for Abilify (Aripiprazole)
Aripiprazole (Abilify) is FDA-approved for use in children aged 13 years and older for bipolar I disorder and in children aged 6 years and older for other indications such as irritability associated with autism.
Age-Specific Approvals
Aripiprazole has different approved age thresholds depending on the indication:
Bipolar I Disorder:
Other Indications:
- Approved for children as young as 6 years for certain conditions (such as irritability associated with autism)
- Schizophrenia: Typically approved for adolescents (13+ years)
- Tourette's syndrome: Approved for younger children (6+ years) 2
Dosing Considerations
Adolescents (13+ years)
- Starting dose: 10 mg once daily for bipolar disorder 1
- No dosage titration is typically necessary 3
- Efficacy is usually seen within the first few weeks of treatment 3
Children (6-12 years)
- Weight-based dosing is recommended 4
- Lower doses are generally used compared to adolescents
- Tolerability is less favorable in younger children (10-12 years) compared to older adolescents 1
Weight Considerations
- Children weighing more than 40 kg may be dosed as adults 5
- For children under 40 kg, weight-based dosing should be implemented
Safety and Monitoring
Aripiprazole requires careful monitoring, particularly in younger patients:
Common side effects in pediatric populations:
- Sedation
- Weight gain (though less than other atypical antipsychotics)
- Extrapyramidal symptoms (EPS) 1
Monitoring parameters:
- Weight and BMI
- Extrapyramidal symptoms
- Metabolic parameters (glucose, lipids)
- Efficacy and behavioral changes
Important Considerations
- Higher doses (30 mg/day) show less favorable tolerability compared to lower doses (10 mg/day) in adolescents 1
- Off-label prescriptions should be limited as they account for a significant proportion of aripiprazole use worldwide 2
- Aripiprazole has a unique pharmacologic profile as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors, which may explain differences in tolerability profiles compared to other atypical antipsychotics 1
Cautions
- Adverse effects are more pronounced in children and adolescents than in adults 2
- Severe adverse effects often occur in multiple-prescription settings 2
- Post-prescription monitoring is often inadequate but essential 2
- The benefit/risk ratio should be carefully evaluated, especially for off-label use 2
When prescribing aripiprazole, always consider the FDA-approved age thresholds for specific indications, use appropriate weight-based dosing for children under 40 kg, and implement thorough monitoring protocols to ensure safety and efficacy.
