What is the recommended first-line treatment for anxiety in the elderly?

First-Line Treatment for Anxiety in the Elderly

Selective serotonin reuptake inhibitors (SSRIs) are the recommended first-line treatment for anxiety in elderly patients, with sertraline and escitalopram being the preferred options due to their favorable safety profiles and low potential for drug interactions. 1

Recommended Pharmacotherapy Options

First-Line Treatment:

• SSRIs are suggested as first-line pharmacotherapy for anxiety disorders in elderly patients due to their efficacy and favorable side effect profile 1, 2
• Among SSRIs, sertraline and escitalopram are preferred specifically for older adults 1, 3
• For elderly patients, recommended starting doses should be lower than those used in younger adults (approximately 50% of standard adult starting dose) 2, 4

Second-Line Treatment:

• If response to an SSRI is inadequate, options include:
  • Switching to a different SSRI 1
  • Switching to an SNRI such as venlafaxine or duloxetine 1, 5
• SNRIs like duloxetine may be particularly useful when anxiety coexists with pain conditions 5
• Buspirone may be considered as an alternative for relatively healthy older adults, particularly when avoiding sexual side effects is a priority 1

Dosing Considerations for Elderly

• Start at lower doses (typically half the standard adult dose) and titrate slowly 2, 4
• For lorazepam (if needed short-term), the dose should be reduced to 0.25-0.5 mg in elderly patients (maximum 2 mg in 24 hours) 3
• For SNRIs like duloxetine in elderly patients with GAD, initiate at 30 mg once daily for 2 weeks before considering an increase to the target dose of 60 mg/day 5
• Regular monitoring for side effects and drug interactions is essential 2

Medications to Use with Caution or Avoid

• Benzodiazepines should generally be avoided as first-line treatment in the elderly due to:
  • Increased risk of falls 1, 2
  • Cognitive impairment 2
  • Potential for dependence 2
• If benzodiazepines are necessary for short-term use, use lower doses with shorter half-lives 3
• Tricyclic antidepressants (TCAs) should be avoided due to anticholinergic effects and cardiac risks 2, 6
• Paroxetine and fluoxetine should generally be avoided in older adults due to higher rates of adverse effects 3
• Antipsychotics should be used with extreme caution given their black box warning for increased mortality in elderly patients with dementia 2

Special Considerations for Elderly Patients

• Always assess for potential drug interactions, as elderly patients are often on multiple medications 6
• SSRIs with lower potential for drug interactions (like sertraline and escitalopram) are preferred 7, 6
• Consider renal and hepatic function when selecting and dosing medications 5
• Monitor for hyponatremia, which occurs more commonly with SSRI use in the elderly 2
• Address non-pharmacological approaches concurrently, including:
  • Exploring the patient's concerns and anxieties 3
  • Ensuring effective communication and orientation 3
  • Treating reversible causes of anxiety (e.g., hypoxia, urinary retention, constipation) 3

Treatment Duration

• For a first episode of anxiety, treatment should continue for at least 4-12 months after symptom remission 3
• For recurrent anxiety, longer-term or indefinite treatment may be beneficial 3
• Regular reassessment of the need for continued treatment is recommended 5
