From the Guidelines
Aripiprazole (Abilify) is a recommended treatment for irritability associated with autism spectrum disorder (ASD) in children and adolescents aged 6-17 years, as it has been shown to significantly reduce challenging behaviors such as aggression, self-injury, and severe tantrums. The medication works as a partial dopamine agonist, helping to balance dopamine and serotonin activity in the brain, which may be dysregulated in autism 1. According to a study published in the Journal of the American Academy of Child and Adolescent Psychiatry, aripiprazole has been found to improve behavioral symptoms in children with ASD, with 56% of patients showing a positive response to the medication at a dose of 5 mg/day 1.
The typical starting dose of aripiprazole for treating irritability in ASD is 2mg daily, which may be gradually increased to an effective dose, usually between 5-15mg daily based on response and tolerability 1. Treatment duration is individualized, with regular monitoring for effectiveness and side effects. Common side effects of aripiprazole include weight gain, sedation, and metabolic changes, requiring regular monitoring of weight, blood glucose, and lipid levels 1.
It's essential to note that while aripiprazole treats specific behavioral symptoms, it does not address core autism features like social communication difficulties or restricted interests. This medication should be used as part of a comprehensive treatment plan that includes behavioral therapies and educational interventions. The use of aripiprazole in children and adolescents with ASD has been supported by randomized controlled trials, including a study published in 2014, which found that the medication was effective in reducing irritability, hyperactivity, and stereotypy in children with ASD 1.
Key points to consider when prescribing aripiprazole for ASD include:
- Starting with a low dose and gradually increasing as needed and tolerated
- Regular monitoring of side effects, including weight, blood glucose, and lipid levels
- Using the medication as part of a comprehensive treatment plan that includes behavioral therapies and educational interventions
- Individualizing treatment duration and dose based on response and tolerability
- Being aware of the potential for common side effects, such as weight gain, sedation, and metabolic changes 1.
From the Research
Role of Aripiprazole in Treating Autism
- Aripiprazole, also known as Abilify, is an atypical antipsychotic that has been approved for the treatment of irritability associated with autism spectrum disorders (ASD) 2, 3, 4, 5, 6.
- The medication has been shown to be effective in reducing irritability, aggression, and self-injurious behavior in individuals with ASD, particularly in children and adolescents 3, 4, 5, 6.
- Studies have demonstrated that aripiprazole can improve symptoms of irritability, hyperactivity, and stereotypy in individuals with ASD, with significant improvements seen in the Aberrant Behavior Checklist (ABC) subscale scores 4, 5, 6.
Efficacy and Safety
- Aripiprazole has been found to be generally well-tolerated in individuals with ASD, with most adverse events being mild to moderate in severity 3, 4, 5, 6.
- Common side effects of aripiprazole include weight gain, sedation, drooling, and tremor, which should be carefully monitored in individuals with ASD 4, 5, 6.
- The medication has been associated with significant improvements in global functioning and quality of life for individuals with ASD and their caregivers 3, 4, 5, 6.
Dosage and Administration
- The recommended dosage of aripiprazole for the treatment of irritability associated with ASD is 5-15 mg per day, with flexible dosing depending on individual response and tolerability 3, 5, 6.
- Aripiprazole can be administered orally, and its efficacy and safety have been established in short-term and long-term studies 4, 5, 6.
Clinical Implications
- Aripiprazole is an important treatment option for individuals with ASD who exhibit irritability, aggression, and self-injurious behavior, and should be considered as part of a comprehensive treatment plan 2, 3, 4, 5, 6.
- Healthcare providers should carefully monitor individuals with ASD who are taking aripiprazole for potential side effects and adjust the dosage as needed to minimize adverse effects 4, 5, 6.
