What is the recommended treatment for depression with anxiety?

Treatment of Depression with Anxiety

For patients with symptoms of both depression and anxiety, treatment of depressive symptoms should be prioritized, or alternatively, a unified protocol combining cognitive behavioral therapy (CBT) treatments for depression and anxiety may be used. 1

First-Line Treatment Approach

Psychological Interventions

• Cognitive Behavioral Therapy (CBT) is highly recommended as first-line treatment:
  • Should be structured with approximately 14 individual sessions over 4 months (60-90 minutes per session) 1
  • Based on the Clark and Wells model or Heimberg model 1
  • Individual therapy is preferred over group therapy due to superior clinical and economic effectiveness 1
  • Self-help with support based on CBT is an alternative if face-to-face CBT is not desired 1

Pharmacological Interventions

• Selective Serotonin Reuptake Inhibitors (SSRIs) are the first-line pharmacological treatment:
  • Escitalopram 10mg daily (can be increased to 20mg after minimum one week if needed) 2
  • Sertraline is particularly effective for patients with psychomotor agitation and melancholia 3
  • Start with lower doses and increase gradually to minimize initial anxiety exacerbation 4

Treatment Monitoring and Evaluation

• Regular assessment of treatment response is essential:
  • For psychological treatment: assess at pretreatment, 4 weeks, 8 weeks, and end of treatment 1
  • For pharmacological treatment: assess at 4 and 8 weeks using standardized validated instruments 1
  • Monitor for symptom relief, side effects, and patient satisfaction 1

Treatment Adjustment Strategy

If little improvement after 8 weeks despite good adherence:

1. Adjust the regimen:

   • Add psychological intervention to pharmacological treatment or vice versa
   • Change medication if using pharmacotherapy
   • Switch from group therapy to individual therapy if applicable 1

2. Medication alternatives if first SSRI fails:

   • Switch to venlafaxine (SNRI) which is particularly effective when fluoxetine fails 3
   • Consider mirtazapine for faster onset of action and benefits for patients with insomnia 3, 4
   • Approximately 25% of patients become symptom-free after switching from a failed antidepressant 3

Special Considerations

• Stepped-care model is strongly recommended:

  • Select the most effective and least resource-intensive intervention based on symptom severity
  • Consider psychiatric history, substance use history, prior treatment response, and comorbidities 1

• Potential pitfalls:

  • SSRIs may initially increase anxiety symptoms (jitteriness, agitation, insomnia) 4
  • Even mild residual symptoms significantly increase relapse risk 3
  • Screen for bipolar disorder before starting antidepressants 2
  • Gradual dose reduction rather than abrupt cessation is recommended when discontinuing treatment 2

• Treatment goals:

  • Aim for full remission rather than partial response 3
  • Target PHQ-9 score ≤2 3

Maintenance Treatment

• For major depressive disorder: several months or longer of sustained pharmacological therapy beyond response to acute episode 2
• For generalized anxiety disorder: efficacy beyond 8 weeks has not been systematically studied 2
• Periodically reassess to determine the need for maintenance treatment 2
