What are the recommended treatments for acute anxiety?

Treatment Options for Acute Anxiety

For acute anxiety treatment, first-line options include benzodiazepines for immediate relief, while SSRIs or SNRIs are recommended for ongoing management, with cognitive behavioral therapy strongly recommended as either standalone or adjunctive treatment. 1

Pharmacological Interventions

Immediate Relief

• Benzodiazepines are highly effective for acute anxiety due to their rapid onset of action and can be used for short-term management of severe anxiety symptoms 2
• For episodic anxiety, shorter-acting benzodiazepines such as oxazepam or lorazepam are preferred, while sustained anxiety may respond better to longer-acting options like diazepam 3
• Benzodiazepines should generally be limited to short courses (ideally 4 weeks maximum) to prevent tolerance, dependence, and withdrawal effects 2

Ongoing Management

• SSRIs are recommended as first-line pharmacotherapy for most anxiety disorders, including:
  • Escitalopram, paroxetine, and sertraline, which have demonstrated efficacy in treating social anxiety disorder 4
  • Paroxetine has FDA approval for generalized anxiety disorder at a recommended initial dose of 20mg/day 5
• SNRIs such as venlafaxine are effective alternatives when SSRIs are not tolerated or ineffective 4, 1
• Pregabalin is considered a first-line option in some guidelines, particularly for generalized anxiety disorder 4

Psychological Interventions

• Cognitive behavioral therapy (CBT) is strongly recommended as a first-line treatment for anxiety disorders, with evidence supporting its efficacy as either standalone or adjunctive therapy 1
• Individual CBT sessions are preferred over group therapy due to superior clinical and economic effectiveness 4
• For patients who cannot or do not want face-to-face therapy, self-help with support based on CBT principles is a viable alternative 4
• CBT should be structured with approximately 14 sessions over 4 months, with each session lasting 60-90 minutes 4

Treatment Algorithm for Acute Anxiety

Step 1: Assessment and Initial Management

• For severe, acute anxiety requiring immediate intervention:
  • Consider a benzodiazepine for short-term relief (1-7 days) 2
  • Diazepam is often the drug of choice for short courses 2
  • Monitor closely for side effects, particularly in elderly patients 2

Step 2: Establish Ongoing Treatment

• Initiate an SSRI or SNRI for ongoing management 4
  • Start with escitalopram, paroxetine, or sertraline as first-line options 4
  • Begin at lower doses and titrate up as needed and tolerated 5
• Concurrently refer for CBT with a skilled therapist 4
• If medication is ineffective after 8 weeks despite good adherence:
  • Consider switching to another SSRI/SNRI or adding a psychological intervention if not already implemented 1
  • For patients not responding to SSRIs, consider switching to an SNRI like venlafaxine 4

Special Considerations

• Benzodiazepines should be avoided for routine or long-term use due to risks of dependence and withdrawal 6
• For patients with comorbid depression and anxiety, prioritize antidepressant treatment over benzodiazepines 7
• Elderly patients, debilitated patients, or those with severe renal or hepatic impairment should start at lower doses (e.g., 10mg/day for paroxetine) 5
• After remission, medications should be continued for 6-12 months to prevent relapse 6
• Regular monitoring of treatment response using standardized instruments is essential for evaluating effectiveness 1

Common Pitfalls to Avoid

• Using benzodiazepines for extended periods (beyond 4 weeks) increases risk of dependence and should be avoided 2
• Discontinuing medication too early after symptom improvement can lead to relapse 6
• Failing to provide adequate psychoeducation about expected timeframe for improvement with SSRIs/SNRIs (typically 2-4 weeks for initial effects) 7
• Neglecting to assess for comorbid conditions like depression, substance abuse, or other anxiety disorders that may influence treatment selection 7
• Underutilizing psychological interventions like CBT, which have strong evidence for effectiveness in anxiety disorders 4, 1
