Treatment Options for Anxiety and Panic Attacks
Start with an SSRI—specifically escitalopram (10-20 mg/day) or sertraline (50-200 mg/day)—as first-line pharmacotherapy, and simultaneously refer for individual cognitive behavioral therapy (CBT) targeting anxiety patterns, as this combination provides superior outcomes compared to either treatment alone. 1, 2
Pharmacologic Treatment Algorithm
First-Line Medications
- Selective serotonin reuptake inhibitors (SSRIs) are the preferred initial pharmacotherapy due to established efficacy, favorable safety profiles, and low risk of dependence 3, 1, 4
- Escitalopram and sertraline are top-tier choices because they have the least drug-drug interactions and lower discontinuation symptoms compared to other SSRIs 1, 2
- Start escitalopram at 5-10 mg daily and titrate by 5-10 mg increments every 1-2 weeks to a target of 10-20 mg/day 1
- Start sertraline at 25-50 mg daily and increase by 25-50 mg increments every 1-2 weeks to a target of 50-200 mg/day 1
- Expect a delayed response: statistically significant improvement begins at week 2, clinically meaningful improvement by week 6, and maximal benefit by week 12 or later 1
Second-Line Medications (If First SSRI Fails After 8-12 Weeks)
- Switch to a different SSRI (e.g., from sertraline to escitalopram or vice versa) before moving to other medication classes 1
- Venlafaxine extended-release (SNRI) at 75-225 mg/day is an effective alternative for generalized anxiety disorder, panic disorder, and social anxiety disorder 3, 1, 4
- Duloxetine (SNRI) at 60-120 mg/day can be considered, particularly if comorbid pain conditions exist 1
- Paroxetine and fluvoxamine are equally effective but reserved as second-tier options due to higher discontinuation symptoms and drug interaction potential 1, 2
Medications to Avoid or Use Cautiously
- Benzodiazepines should be reserved for short-term use only (days to weeks, not months) due to risks of dependence, tolerance, cognitive impairment, and withdrawal syndrome 3, 4
- Benzodiazepines may be used temporarily during the first 2-4 weeks of SSRI initiation to bridge the gap before onset of antidepressant effect, then tapered off 5, 6
- Tricyclic antidepressants should be avoided as first-line treatment due to unfavorable cardiac toxicity and side effect profiles 1
Non-Pharmacologic Treatment Approach
Cognitive Behavioral Therapy (Core Intervention)
- Individual CBT is the psychotherapy with the highest level of evidence for anxiety and panic disorders, demonstrating small to medium effect sizes compared to placebo 2
- Individual sessions are preferred over group therapy due to superior clinical and cost-effectiveness 3, 2
- Structured duration of 12-20 sessions is recommended to achieve significant symptomatic and functional improvement 1, 2
- Core CBT elements include: psychoeducation about anxiety, cognitive restructuring to challenge distorted thoughts, relaxation techniques (breathing exercises, progressive muscle relaxation), and graduated exposure therapy 1, 2
- Graduated exposure therapy is the cornerstone for situation-specific anxiety, where patients create a fear hierarchy and master it stepwise 2
- If face-to-face CBT is unavailable or not preferred, self-help CBT with professional support is a viable alternative 3, 2
Adjunctive Non-Pharmacologic Strategies
- Structured physical activity and regular cardiovascular exercise provide moderate to large reductions in anxiety symptoms 1, 2
- Breathing techniques, progressive muscle relaxation, grounding strategies, visualization, and mindfulness are useful adjuncts to primary treatment 1, 2
- Avoid excessive caffeine and alcohol as both can exacerbate anxiety symptoms 2
- Sleep hygiene education should be provided, as insomnia commonly co-occurs with anxiety 2
Combined Treatment Strategy (Optimal Approach)
- For moderate to severe anxiety or panic disorder, combination treatment (SSRI + CBT) provides superior outcomes compared to either treatment alone, with moderate strength of evidence 1, 2
- The combination addresses both neurochemical dysregulation and maladaptive cognitive-behavioral patterns 3, 2
Monitoring and Treatment Adjustment
- Assess treatment response at 4 weeks and 8 weeks using standardized validated instruments such as the GAD-7 or Hamilton Anxiety Rating Scale (HAM-A) 1, 2
- Monitor for common SSRI side effects: nausea, sexual dysfunction, headache, insomnia, dry mouth, diarrhea, somnolence, and dizziness—most emerge within the first few weeks and typically resolve with continued treatment 1
- Critical warning: All SSRIs carry a boxed warning for suicidal thinking and behavior, with pooled absolute rates of 1% versus 0.2% for placebo; close monitoring is essential, especially in the first months and following dose adjustments 1
- If no improvement after 8-12 weeks at therapeutic doses despite good adherence, switch to a different SSRI or SNRI, or add CBT if not already implemented 1, 2
- Continue effective medication for a minimum of 9-12 months after achieving remission to prevent relapse 1
Common Clinical Pitfalls to Avoid
- Never discontinue SSRIs abruptly—taper gradually over 10-14 days to avoid discontinuation syndrome, particularly with shorter half-life SSRIs like sertraline and paroxetine 1, 2
- Do not escalate SSRI doses too quickly—allow 1-2 weeks between increases to assess tolerability and avoid overshooting the therapeutic window 1
- Do not abandon treatment prematurely—full response may take 12+ weeks, and patience in dose escalation is crucial for optimal outcomes 1
- Do not use benzodiazepines as first-line or long-term treatment due to dependence risk and cognitive impairment 3, 4
- Patients with anxiety commonly avoid follow-through on referrals—proactively assess and address barriers to treatment adherence, particularly for CBT referrals 3, 1
Special Considerations for Panic Attacks Specifically
- SSRIs demonstrate high-quality evidence for panic disorder, showing improvement in panic symptoms, treatment response, and remission rates 1, 5, 6
- Alprazolam (benzodiazepine) has specific anti-panic efficacy but requires slow dose reduction and carries a 30% risk of withdrawal reactions, limiting its use to short-term or treatment-resistant cases 7
- Cognitive-behavioral therapy has demonstrated efficacy in both acute and long-term treatment of panic disorder, and an integrated approach combining pharmacotherapy with CBT may provide the best outcomes 6
Treatment Selection Based on Patient Factors
- Base treatment choice on shared decision-making, considering availability, accessibility, patient preference, likelihood of adherence, and cost 2
- Inform patients about common side effects to improve adherence and set realistic expectations about the timeline for therapeutic benefit 1, 2
- Provide psychoeducation to family members about anxiety symptoms and treatment, and consider referral for treatment for parents or caregivers who struggle with anxiety themselves 2
