What is the first line treatment for anxiety?

First-Line Treatment for Anxiety Disorders

Selective Serotonin Reuptake Inhibitors (SSRIs) and Cognitive Behavioral Therapy (CBT) are the first-line treatments for anxiety disorders, with combination therapy often providing the most effective outcomes for moderate to severe cases. 1

Treatment Algorithm

Initial Assessment and Treatment Selection

1. Severity-Based Approach:

   • Mild anxiety: Start with CBT alone
   • Moderate to severe anxiety: Consider combination of CBT and SSRI/SNRI simultaneously 1

2. First-Line Pharmacotherapy Options:

   • SSRIs: Sertraline, escitalopram, paroxetine, fluvoxamine 1
   • SNRIs: Duloxetine (FDA-approved for generalized anxiety disorder), venlafaxine 1
   • Starting doses: Lower doses initially with gradual titration
     • Example: Fluoxetine 20mg daily (range 20-30mg/day) 2

3. First-Line Psychotherapy Option:

   • Individual CBT: Preferred over group therapy due to superior clinical and economic effectiveness 1
   • Self-help CBT with support: Alternative if patient declines face-to-face therapy 1

Medication Management

• Initiation: Start at lower doses, especially in elderly, hepatic/renal impairment patients 1, 2
• Titration: Increase dose gradually if no response after 4-6 weeks 1
• Duration: Continue effective medication for at least 6-12 months after symptom remission 1
• Discontinuation: Taper gradually to avoid withdrawal symptoms 1, 2

Important Considerations

• Avoid benzodiazepines as first-line: Despite FDA approval for anxiety (e.g., alprazolam), benzodiazepines are not recommended for routine use due to dependency risk 1, 3, 4
• Special populations:
  • Children/adolescents: SSRIs are first-line with monitoring for suicidal ideation 1
  • Elderly: Start with lower doses and titrate more slowly 1
  • Pregnancy/lactation: SSRIs may be used with caution when benefits outweigh risks 1

Treatment Monitoring

• Assess response: After 4-6 weeks of medication 1
• Adjust treatment plan based on response:
  • Consider increasing dose of antidepressant
  • Intensify CBT
  • Consider alternative or augmentation strategies for treatment resistance 1

Lifestyle Modifications as Adjuncts

• Regular exercise
• Good sleep hygiene
• Mindfulness and meditation
• Limiting screen time
• Spending time in nature 1

Common Pitfalls to Avoid

1. Using benzodiazepines as first-line treatment: Despite quick relief, they carry significant risk of dependence 4
2. Inadequate duration of treatment: Anxiety disorders are chronic conditions requiring long-term management 5
3. Abrupt discontinuation: Always taper medications gradually to minimize withdrawal symptoms 1, 2
4. Overlooking comorbidities: Depression, substance use disorders, and other anxiety disorders often co-occur and may require additional targeted interventions 1
5. Insufficient dose or duration before concluding treatment failure: Some patients require higher doses or longer treatment periods before experiencing benefit 6

The evidence strongly supports that both CBT and SSRIs/SNRIs are effective first-line treatments for anxiety disorders, with combination therapy often providing superior outcomes for moderate to severe cases 1, 7, 5. This approach addresses both the neurobiological and psychological aspects of anxiety disorders, leading to more sustainable improvements in morbidity, mortality, and quality of life.
