What is the recommended first‑line management for a child or adolescent with panic disorder?

Treatment of Panic Disorder in Children and Adolescents

Cognitive-behavioral therapy (CBT) should be the first-line treatment for children and adolescents with panic disorder, particularly for mild to moderate presentations, with SSRIs reserved for severe cases or when quality CBT is unavailable. 1, 2

Treatment Algorithm

Step 1: Initial Assessment and First-Line Treatment

For mild to moderate panic disorder:

• Initiate individual CBT consisting of 12-20 structured sessions delivered over 3-4 months 2, 3
• CBT components should include psychoeducation about panic disorder, cognitive restructuring to challenge catastrophic misinterpretations of bodily sensations, interoceptive exposure to feared physical sensations, and in vivo exposure to avoided situations 4, 5
• Individual CBT demonstrates moderate to high strength of evidence for improving anxiety symptoms, global function, and treatment response compared to inactive controls 2, 3

For severe panic disorder or significant functional impairment:

• Consider combination treatment with CBT plus an SSRI from the outset, as this approach demonstrates superior efficacy to either treatment alone 1, 2, 5
• The Child-Adolescent Anxiety Multimodal Study (CAMS) showed that 80.7% of children receiving combination therapy were rated as "very much" or "much improved" compared to 59.7% with CBT alone and 54.9% with sertraline alone 5

Step 2: Pharmacotherapy When Indicated

SSRI selection and dosing for children ≥6 years:

• Start with sertraline 25 mg daily or fluoxetine 5-10 mg daily to minimize initial anxiety or activation symptoms 2
• Titrate sertraline by 25-50 mg increments every 1-2 weeks to a target of 50-200 mg/day 2
• Titrate fluoxetine by 5-10 mg increments every 1-2 weeks to a target of 20-40 mg/day 2
• SSRIs demonstrate high strength of evidence for improving global function and moderate strength of evidence for improving clinician-reported anxiety symptoms, with a number needed to treat (NNT) of 3 2, 6

Expected timeline:

• Statistically significant improvement may begin by week 2, clinically meaningful improvement by week 6, and maximal benefit by week 12 or later 2
• Do not abandon treatment prematurely; full response requires 12+ weeks at therapeutic doses 2

Step 3: Management of Inadequate Response

If insufficient improvement after 8-12 weeks at therapeutic SSRI doses:

• Switch to a different SSRI (e.g., from sertraline to escitalopram or fluoxetine) 2
• Add individual CBT if not already implemented 2, 6
• Consider an SNRI such as venlafaxine extended-release 75-225 mg/day as a second-line option, though evidence is less robust in children 1, 2

Critical Safety Monitoring

Suicidality surveillance is mandatory:

• All SSRIs carry a boxed warning for suicidal ideation and behavior through age 24 years 2
• The pooled absolute rate for suicidal ideation is 1% with SSRIs versus 0.2% with placebo (risk difference 0.7%, NNH = 143) 2
• Monitor closely during the first months of treatment and following any dosage adjustments 2
• The benefit-to-risk ratio remains highly favorable given the NNT of 3 versus NNH of 143 2

Common adverse effects to anticipate:

• Nausea, headache, insomnia, nervousness, and activation symptoms typically emerge within the first few weeks and often resolve with continued treatment 2
• Starting at low doses and titrating gradually minimizes these initial side effects 2

Common Pitfalls to Avoid

Do not use benzodiazepines in pediatric panic disorder:

• Benzodiazepines lack efficacy data in children and carry high risks of dependence, tolerance, and withdrawal 2, 7, 6
• They are explicitly not recommended by the American Academy of Child and Adolescent Psychiatry 7

Do not start with medication alone for mild-to-moderate presentations:

• CBT has fewer adverse effects and lower relapse rates after treatment completion compared to pharmacotherapy 2
• Medication should be reserved for severe cases, significant functional impairment, or when CBT is unavailable 1, 2

Do not discontinue SSRIs abruptly:

• Gradual tapering over 10-14 days (or longer) is essential to minimize discontinuation symptoms, which are particularly problematic with shorter half-life SSRIs like sertraline and paroxetine 2

Do not exceed optimal dosing by titrating too rapidly:

• The dose-response relationship for SSRIs is logarithmic, not linear, meaning diminishing returns occur at higher doses 2
• Slow titration prevents overshooting the therapeutic window and reduces side effects 2

Special Considerations

Family involvement:

• Provide psychoeducation to family members about panic disorder symptoms and treatment 2
• Consider referral for treatment of parents or caregivers who struggle with anxiety themselves, as parental anxiety can interfere with child treatment outcomes 2

Adjunctive strategies:

• Teach breathing techniques, progressive muscle relaxation, grounding strategies, and mindfulness as useful adjuncts to primary treatment 2
• Encourage regular cardiovascular exercise, which provides moderate to large reductions in anxiety symptoms 2

Long-term management:

• Continue effective medication for a minimum of 9-12 months after achieving remission to prevent relapse 8
• Early response to treatment (by week 4-6) strongly predicts long-term outcomes 2
