Understanding Behavioral Challenges in Autism
Autism Spectrum Disorder (ASD) is a developmental condition characterized by challenges with social communication and restricted, repetitive behaviors. Many individuals with autism also experience aggressive behaviors like severe tantrums, self-injury, and outbursts, which some studies suggest affects at least half of this population. These behaviors often arise from factors such as communication difficulties, sensory overload, anxiety, or frustration and can significantly impact daily life. While behavioral therapies like Applied Behavior Analysis (ABA) are the primary approach for the core symptoms and related behaviors of autism, medication is sometimes used as an additional treatment for severe irritability and aggression when behavioral interventions are not enough. Importantly, no medication treats the core symptoms of autism itself; they only target specific challenging behaviors.
FDA-Approved Medications for Irritability in Autism
Only two medications have been approved by the U.S. Food and Drug Administration (FDA) specifically for treating irritability linked to autistic disorder in children and adolescents: risperidone and aripiprazole. Both are atypical, or second-generation, antipsychotics.
Risperidone (Risperdal)
Approved by the FDA in 2006 for individuals with autism aged 5-16, risperidone targets irritability. It affects dopamine and serotonin receptors in the brain and has been shown in clinical trials to reduce aggression, self-injurious behaviors, and temper tantrums. However, common side effects include significant weight gain, increased appetite, drowsiness, and fatigue. Long-term use carries risks of metabolic changes, potentially leading to diabetes and heart disease, and hormonal changes like elevated prolactin levels. Monitoring by a healthcare provider is essential.
Aripiprazole (Abilify)
Aripiprazole received FDA approval in 2009 for treating irritability in individuals with autism aged 6-17. It works as a partial agonist on certain dopamine and serotonin receptors. Studies indicate its effectiveness in reducing irritability and hyperactivity. Both risperidone and aripiprazole are considered equally effective for irritability. Aripiprazole may have a slightly better side-effect profile, with less weight gain and no significant increase in prolactin levels compared to risperidone. However, common side effects include weight gain, fatigue, drowsiness (somnolence), and vomiting.
Comparison of FDA-Approved Medications
| Feature | Risperidone (Risperdal) | Aripiprazole (Abilify) |
|---|---|---|
| FDA Approval | Approved in 2006 for ages 5-16 for irritability in autism. | Approved in 2009 for ages 6-17 for irritability in autism. |
| Efficacy | Effective in reducing irritability, aggression, and self-injury. | Effective in reducing irritability and hyperactivity. Considered equally effective to risperidone. |
| Common Side Effects | Significant weight gain, increased appetite, drowsiness, fatigue. | Weight gain (less than risperidone), drowsiness, fatigue, vomiting. |
| Key Risks | High risk of elevated prolactin, metabolic syndrome, diabetes. | Lower risk of elevated prolactin compared to risperidone. Risk of weight gain and metabolic changes still present. |
Off-Label Medications
Other medications may be used off-label to manage co-occurring conditions that can contribute to tantrums and behavioral issues. These often include ADHD, anxiety, depression, and sleep problems.

The Importance of a Holistic Approach
Experts emphasize that medication should always be part of a comprehensive treatment plan. This plan should include behavioral therapies, such as Applied Behavior Analysis (ABA). ABA helps identify why aggressive behaviors occur and teaches alternative ways to communicate needs and manage emotions. The combination of medication, parent training, and behavioral therapy is more effective than medication alone. Strategies like environmental adjustments, sensory support, and consistent routines are also vital non-pharmacological methods for preventing and managing meltdowns.
Conclusion
When considering what medication is used for autistic tantrums, the main options are the two FDA-approved atypical antipsychotics, risperidone and aripiprazole, which address severe irritability and aggression. The choice between these often involves weighing their effectiveness against potential significant side effects like weight gain and metabolic changes. Other medications might be used off-label for co-occurring conditions. Ultimately, managing behavioral challenges in autism relies on a holistic approach that prioritizes behavioral interventions, parent support, and environmental modifications, with medication serving as a supplementary tool for severe symptoms.
