What is Aripiprazole?
Atypical antipsychotic medication approved for treating irritability associated with autism.
Research
Evidence Summary
Current research on aripiprazole for autism remains quite limited. Six studies have examined this medication, with most showing limited or emerging evidence of effectiveness. One study provided moderate-quality evidence, though the overall participant numbers across research were small. Parents considering this option should discuss potential benefits and risks with their child's doctor, as evidence alone cannot yet determine whether it would help their individual child.

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

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

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