What are the treatment options for irritability?

Treatment Options for Irritability

Cognitive behavioral therapy (CBT) is the first-line treatment for irritability, focusing on emotion regulation, problem-solving skills, and identification of triggers, while pharmacological options including risperidone or aripiprazole should be reserved for severe cases. 1

Understanding Irritability

• Irritability is a transdiagnostic symptom primarily conceptualized as mood dysregulation, which may be accompanied by behavioral outbursts and has a clear cognitive component 1
• Irritability is negatively associated with age, with individuals having lower developmental ability potentially scoring higher on measures of irritability due to fewer cognitive resources for mood regulation 1
• Irritability can be a standalone symptom or appear in various conditions including depression, anxiety disorders, autism spectrum disorder, and disruptive mood dysregulation disorder 2, 3

Non-Pharmacological Interventions

Psychological Approaches

• Cognitive behavioral therapy (CBT) is recommended as first-line treatment for irritability, targeting deficits in emotion regulation and social problem-solving associated with aggressive behavior 1
• CBT focuses on remediating psychological factors that impact symptom perception, including anger management techniques, problem-solving skills, stress reduction, and identification of triggers 1
• Parent management training (PMT) helps parents develop strategies to prevent aggressive behavior and de-escalate situations, particularly effective for children and adolescents with irritability 1
• Hypnotherapy, relaxation techniques, and biofeedback procedures aimed at managing stress have been reported to improve irritability symptoms 1
• Brain-gut behavior therapy can be effective for irritability associated with gastrointestinal disorders like IBS 4

Pharmacological Interventions

First-Line Medications

• For severe irritability and aggression, particularly in patients with autism spectrum disorder, risperidone or aripiprazole are recommended first-line pharmacological treatments 1
• Atypical antipsychotics are generally preferred over first-generation antipsychotics due to reduced risk of extrapyramidal symptoms 1

Second-Line Medications

• Tricyclic antidepressants (TCAs) can be effective for irritability, particularly at low doses 5, 4
• Selective serotonin reuptake inhibitors (SSRIs) like sertraline or fluoxetine may be considered for irritability associated with mood disorders 1, 6
• When prescribing SSRIs, clinicians must monitor for increased risk of suicidal thinking and behavior, particularly in children, adolescents, and young adults (ages 18-24) 7
• Mood stabilizers such as valproate can be effective for treating irritability, particularly when other treatments have failed 6
• Buspirone may be considered as an alternative or add-on treatment for irritability 6

Integrated Treatment Approach

• The American Academy of Child and Adolescent Psychiatry recommends that treatment plans include strategies to prevent aggressive behavior, de-escalate behavior before restrictive interventions become necessary, and address underlying psychopathology 1
• Combining medication with behavioral interventions is more efficacious than medication alone for decreasing serious behavioral disturbance 1
• Regular assessment of treatment response using standardized rating scales is recommended 1

Special Populations

Children and Adolescents

• For children with intellectual disability and irritability, psychotropic medications should proceed from diagnosis of a DSM-5 psychiatric disorder and be part of a comprehensive treatment plan 1
• Higher IQ is associated with better outcomes for irritability treatment, likely because more cognitively able individuals have more resources to regulate their mood 1

Irritability with Comorbid Conditions

• For patients with irritable bowel syndrome (IBS) and irritability, an integrated approach addressing both physical and psychological symptoms is recommended 5, 4
• In Huntington's disease, SSRIs or mood stabilizers like valproate are recommended as first-line treatments for irritability 6

Important Considerations and Pitfalls

• Pharmacological interventions can be associated with notable side effects that require careful monitoring 1
• When prescribing SSRIs, monitor for emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and mania 7
• Screen patients for bipolar disorder before initiating antidepressant treatment, as treating a depressive episode with an antidepressant alone may increase the likelihood of precipitating a mixed/manic episode 7
• Prescriptions for antidepressants should be written for the smallest quantity consistent with good patient management to reduce the risk of overdose 7
