Treatment of Panic Attacks
First-Line Treatment: SSRIs Combined with Cognitive Behavioral Therapy
The optimal initial treatment for panic attacks is an SSRI (sertraline or escitalopram) combined with cognitive behavioral therapy, with individual CBT preferred over group therapy. 1, 2
Recommended SSRI Regimens
Sertraline (preferred first-line option):
- Start with 25 mg daily for the first week to minimize initial anxiety or agitation that commonly occurs with SSRI initiation in panic disorder patients 1, 2, 3
- Increase to 50 mg daily after week 1 1, 2
- Target therapeutic dose: 50-200 mg/day, with dose increases of 25-50 mg every 1-2 weeks as needed 1, 3
- Administer once daily, morning or evening 3
Escitalopram (alternative first-line option):
- Start with 5-10 mg daily 1, 4
- Titrate by 5-10 mg increments every 1-2 weeks 1, 4
- Target dose: 10-20 mg/day 1, 4
Critical Rationale for Low Starting Doses
Panic disorder patients are hypersensitive to physical sensations and commonly experience initial anxiety or agitation when starting SSRIs, making subtherapeutic "test" doses essential to minimize early treatment dropout 1. This initial worsening can paradoxically increase panic symptoms in the first 1-2 weeks 5.
Expected Response Timeline
- Statistically significant improvement may begin by week 2 1, 2
- Clinically significant improvement expected by week 4-6 1
- Maximal therapeutic benefit achieved by week 12 1, 2, 4
- Do not abandon treatment before 12 weeks at therapeutic dose 1, 2
Cognitive Behavioral Therapy Integration
CBT should be initiated concurrently with medication, not sequentially. 1, 2, 4
CBT Components for Panic Disorder
- Education on anxiety mechanisms and the fight-or-flight response 6
- Cognitive restructuring to challenge catastrophic thinking patterns (e.g., "I'm having a heart attack") 6, 1
- Graduated exposure to feared physical sensations and situations 6
- Relaxation techniques including breathing retraining and progressive muscle relaxation 6
- Sensory grounding techniques to prevent dissociation during panic episodes 6
- Structured treatment course of 12-20 sessions 1, 2, 4
Evidence for Combination Treatment
Combination treatment (SSRI plus CBT) demonstrates superior response rates and remission compared to either treatment alone 1, 2, 4. Individual CBT is prioritized over group therapy due to superior clinical and cost-effectiveness 1, 2, 4.
Acute Management: Benzodiazepines (Short-Term Only)
For acute panic attacks, benzodiazepines provide rapid symptom relief but should only be used short-term (first few weeks) while waiting for SSRI onset of action. 1
Benzodiazepine Protocol
- Alprazolam 0.5 mg three times daily initially, may increase to maximum 4 mg/day in divided doses 7
- For panic disorder specifically: doses of 1-10 mg/day have been used, with mean effective dose of 5-6 mg/day 7
- Titrate slowly at intervals of 3-4 days 7
- Taper and discontinue after 2-4 weeks once SSRI begins working 1
- Decrease by no more than 0.5 mg every 3 days when discontinuing 7
Critical Contraindications for Benzodiazepines
Avoid benzodiazepines entirely in patients with: 1
- History of substance use disorder
- Respiratory disorders
- Elderly patients
- Need for long-term treatment
Evidence Against Long-Term Benzodiazepine Use
One study found 63% of trauma patients on benzodiazepines developed PTSD versus only 23% on placebo, suggesting benzodiazepines may paradoxically worsen long-term outcomes 6, 2. Benzodiazepines carry significant risks of tolerance, dependence, cognitive impairment, and do not address underlying pathology 1, 4, 5.
Second-Line Options
Alternative SSRIs
If sertraline or escitalopram are not tolerated after 6-8 weeks at therapeutic dose: 1
- Fluoxetine 20-40 mg/day 2
- Avoid paroxetine due to higher discontinuation syndrome risk and potentially increased suicidal thinking 2, 4
SNRIs (Third-Line)
Venlafaxine extended-release 75-225 mg/day can be considered for patients who fail multiple SSRI trials 1, 2, 4. However, venlafaxine requires blood pressure monitoring due to risk of sustained hypertension 1.
Monitoring and Safety
Suicide Risk Monitoring
Monitor closely for suicidal thinking and behavior, especially in the first months and after dose adjustments. 1, 2, 4
- Pooled risk: 1% vs 0.2% placebo 1, 2
- Number needed to harm: 143 1, 2, 4
- Risk is highest in patients under age 25 1
Assessment Schedule
- Assess treatment response at 4-6 weeks using standardized scales (Panic Disorder Severity Scale or Clinical Global Impression) 1, 4
- Monitor for serotonin syndrome, behavioral activation/agitation, and hypomania/mania 1
- Evaluate compliance monthly until symptoms subside, as anxiety patients often avoid follow-through 4
Common Early Side Effects (Usually Resolve)
- Nausea, headache, insomnia, nervousness 2, 8, 9
- Initial anxiety/agitation (most concerning in panic disorder) 1, 2
- Sexual dysfunction (may persist long-term) 2, 8, 9
Treatment Duration and Discontinuation
Maintenance Phase
- Continue SSRI for minimum 9-12 months after achieving remission to prevent relapse 1, 2, 4
- Panic disorder is a chronic condition; many patients require longer-term treatment 10, 3, 9
- Systematic evaluation has demonstrated maintained efficacy for up to 44 weeks 3
Discontinuation Protocol
Taper gradually to avoid discontinuation syndrome (dizziness, fatigue, nausea, sensory disturbances, anxiety). 1, 4
- Decrease by no more than 25-50% every 1-2 weeks 1
- Sertraline and paroxetine (shorter half-life) require slower tapers than fluoxetine 1, 4
- Some patients may require even slower reduction 1
Medications to Avoid
Tricyclic Antidepressants
Despite equal efficacy to SSRIs, tricyclics should be avoided due to unfavorable risk-benefit profile, particularly cardiac toxicity in overdose 1, 4, 11.
Beta-Blockers
Limited evidence for panic disorder; may be used for performance anxiety only, not panic disorder 1.
Special Populations
Children and Adolescents (Ages 6-18)
The American Academy of Child and Adolescent Psychiatry recommends SSRIs for panic disorder in this age group 6:
- Sertraline or escitalopram are preferred 6, 2
- Combination with CBT is superior to monotherapy 6, 2
- Family-directed interventions should supplement individual treatment 6
- School-directed interventions may be incorporated into 504 plans 6
Elderly Patients
- Start alprazolam at 0.25 mg two or three times daily if benzodiazepines are necessary 7
- Elderly patients are especially sensitive to benzodiazepine effects 7
- SSRI dosing may need adjustment due to altered pharmacokinetics 1
Pregnant or Lactating Women
Paroxetine distributes into breast milk at concentrations similar to plasma 8. Risk-benefit analysis should guide treatment decisions, with consideration of untreated panic disorder's impact on maternal and fetal health 11.
Common Pitfalls to Avoid
- Starting SSRI dose too high, causing initial anxiety worsening and treatment dropout 1, 2
- Abandoning treatment before 12 weeks, as full response requires patience 1, 2
- Escalating doses too quickly, not allowing 1-2 weeks between increases 1, 2
- Using long-term benzodiazepines, which cause dependence and may worsen outcomes 6, 1, 2
- Abrupt SSRI discontinuation, causing withdrawal syndrome 1, 4, 7
- Inadequate follow-up, as anxious patients often avoid appointments 4
- Treating medication alone without CBT, missing superior outcomes of combination therapy 1, 2, 4
