What is Aripiprazole?

Atypical antipsychotic medication approved for treating irritability associated with autism.

Evidence Summary

Aripiprazole has been studied as a potential autism intervention across seven research efforts. Most studies show limited evidence quality, with two emerging and one moderate-quality investigation. Current research involves relatively small participant numbers, making it difficult to draw firm conclusions about effectiveness. Parents considering this medication should discuss potential benefits and risks with their healthcare provider, as individual responses vary considerably.

Dyskinesia following modafinil administration in a patient with autism spectrum disorder and narcolepsy: a case report.

Journal of medical case reports2026

Niijima Kuniyuki, Kume Kazuhiko, Murabayashi Naoki et al.

Plain-English summary

A 24-year-old woman with autism and a sleep disorder called narcolepsy developed involuntary muscle movements (dyskinesia) after taking modafinil, a medication used to help with daytime sleepiness. She had previously taken another medication called aripiprazole for autism symptoms. The doctors believe the combination of having autism, previous medication use, and modafinil may have caused these movement problems. This is the first reported case of this side effect in someone with autism.

Catalase Gene Variants and Oxidative Stress in Autism Spectrum Disorder: A Northern Lebanon Cohort and Aripiprazole In Vitro Toxicity.

International journal of developmental neuroscience : the official journal of the International Society for Developmental Neuroscience2025

Bacha Jeanne d'arc, Zoebi Nawal El, Al-Attrache Houssein

Plain-English summary

Researchers studied whether a specific gene variant affects autism risk in 94 Lebanese participants and found no connection. They also tested how the autism medication aripiprazole affects cells in the lab. The medication caused more harm to cells missing certain protective genes, suggesting that a person's genetics might influence how they respond to this treatment.

[Aripiprazole in the treatment of psychiatric disorders in childhood].

Zhurnal nevrologii i psikhiatrii imeni S.S. Korsakova2025

Goryunov A V, Shushpanova O V, Blinova T E

Plain-English summary

This review discusses aripiprazole, a medication approved by the FDA for treating irritability in autistic children and teens. The authors note that aripiprazole can help with various symptoms while having fewer side effects than some other medications - it typically doesn't cause significant weight gain or movement problems. The medication is included in official treatment guidelines for autism and is commonly prescribed because it addresses multiple symptom areas while being generally well-tolerated by young people.

EmergingRandomised Controlled Trial

Efficacy and safety of risperidone and aripiprazole in reducing severity of irritability in children with autism spectrum disorder: A randomized controlled trial.

Brain & development2025

Panda Prateek Kumar, Sharawat Indar Kumar, Gupta Diksha et al.

Plain-English summary

This study compared two medications (risperidone and aripiprazole) for reducing irritability and challenging behaviours in 72 autistic children aged 6-18. Both medications worked equally well at reducing irritability, improving sleep, and helping with other behaviours. Side effects were similar for both medications, but risperidone increased prolactin hormone levels while aripiprazole decreased them. Parents can discuss with doctors that both medications appear to be equally effective options.

Retracing our steps: A review on autism research in children, its limitation and impending pharmacological interventions.

Pharmacology & therapeutics2024

Salloum-Asfar Salam, Zawia Nasser, Abdulla Sara A

Plain-English summary

This review looks at current autism treatments and research gaps. While there are no medications specifically for autism's main symptoms (communication, social skills, repetitive behaviors), doctors can prescribe medications for related issues like aggression, ADHD, and sleep problems. The authors stress that better diagnostic tests and personalized treatments are urgently needed to help children with autism more effectively.

Aripiprazole Used to Treat Capgras Syndrome in an Adolescent Diagnosed With Autism.

Clinical neuropharmacology2023

Baykal Saliha, Mutlu Caner

Plain-English summary

This report describes a rare condition called Capgras syndrome in a teenager with autism. Capgras syndrome makes people believe their family members have been replaced by identical strangers. This had never been reported in someone with autism before. The teenager was treated successfully with a medication called aripiprazole, though higher doses were needed than usual. The treatment worked well without serious side effects.

Long-Term Improvement and Safety of Aripiprazole for Irritability and Adaptive Function in Asian Children and Adolescents with Autistic Disorder: A 52-Week, Multinational, Multicenter, Open-Label Study.

Journal of child and adolescent psychopharmacology2022

Kim Byoung-Uk, Kim Hyo-Won, Park Eun Jin et al.

Plain-English summary

This year-long study followed 58 Asian children and teens (ages 6-17) with autism who took aripiprazole medication. The results showed continued improvements in challenging behaviors, daily living skills, and reduced family stress. Most children tolerated the medication well, though about 6 in 10 experienced some side effects. The most common side effects were common cold symptoms and weight gain. Three serious events happened but weren't caused by the medication.
