Parents often ask, “What is the best mood stabilizer for anger in autism?” Research shows that only a few medications are approved to help manage severe irritability and aggression in autism spectrum disorder (ASD).

Two medications currently approved by the U.S. Food and Drug Administration (FDA) for irritability in autism are risperidone and aripiprazole. These medications may reduce aggression, tantrums, and rapid mood changes when prescribed by a medical professional. 

However, medication is typically used alongside behavioral therapies such as Applied Behavior Analysis (ABA).

Why anger can occur in autism

Anger and irritability in autism may be linked to factors such as:

• sensory overload
• communication challenges
• frustration with routines
• difficulty regulating emotions

Research shows that irritability in ASD can include aggression, self-injury, or severe tantrums.

Because these behaviors may affect safety and learning, clinicians sometimes consider medication when behavioral strategies alone are not enough.

Medications studied for anger in autism

Risperidone

Risperidone was the first medication approved for irritability in autism. Studies show it can reduce aggression and severe behavioral outbursts in children with ASD.

Aripiprazole

Aripiprazole is another FDA-approved option used to treat irritability and mood dysregulation in children with autism. Clinical trials show it can reduce aggressive behaviors and emotional instability. 

These medications are sometimes described as mood stabilizers because they help regulate emotional and behavioral responses.

Example from clinical practice

A child experiencing frequent aggressive outbursts may first receive behavioral intervention such as ABA therapy. If severe irritability continues, a physician may evaluate whether medication combined with therapy could help stabilize behavior.

Studies show that combining behavioral therapy with medical treatment can support better outcomes for some individuals with ASD. 

Conclusion

So, what is the best mood stabilizer for anger in autism? Current medical research identifies risperidone and aripiprazole as the only medications approved to treat irritability related to autism.
