Best Anti-Anxiety Medications for Seniors

For elderly patients with anxiety, SSRIs such as sertraline, escitalopram, and citalopram are the best first-line medications due to their favorable safety profiles, efficacy, and lower risk of adverse effects compared to other classes of anti-anxiety medications. 1

First-Line Medications for Anxiety in Seniors

SSRIs (Selective Serotonin Reuptake Inhibitors)

• Sertraline (Zoloft)

  • Starting dose: 25mg daily (half the standard adult dose)
  • Target dose: 50-200mg daily
  • Benefits: Well-tolerated in elderly, lacks significant anticholinergic effects, low potential for drug interactions 2
  • Particularly effective for both anxiety and depression 1

• Escitalopram (Lexapro)

  • Starting dose: 5mg daily (lower than standard adult dose)
  • Target dose: 10-20mg daily
  • Benefits: Well-established safety profile in elderly, demonstrated efficacy in GAD 3
  • Faster onset of action in elderly patients with panic disorder compared to citalopram 4

• Citalopram (Celexa)

  • Starting dose: 10mg daily
  • Target dose: 20-40mg daily (maximum 20mg in elderly due to QT prolongation risk)
  • Benefits: Favorable adverse effect profile 5

Second-Line Options

SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors)

• Duloxetine (Cymbalta)

  • Starting dose: 20-30mg daily
  • Target dose: 60mg daily
  • Benefits: Effective for both anxiety and depression, additional benefit for pain symptoms 1

• Venlafaxine (Effexor)

  • Starting dose: 37.5mg daily
  • Target dose: up to 225mg daily
  • Caution: May cause hypertension at higher doses 1

Other Options

• Mirtazapine (Remeron)

  • Starting dose: 7.5mg at bedtime
  • Target dose: 15-30mg at bedtime
  • Benefits: Promotes sleep and appetite, well-tolerated in cardiovascular disease 1
  • Particularly useful for elderly patients with insomnia and poor appetite 5

• Buspirone (BuSpar)

  • Starting dose: 5mg twice daily
  • Target dose: up to 20mg three times daily
  • Benefits: Useful for mild to moderate anxiety
  • Limitation: May take 2-4 weeks to become effective 5

Medications to Avoid in Elderly

• Benzodiazepines (lorazepam, oxazepam, temazepam, etc.)

  • Should generally be avoided in elderly patients 6
  • High risk of falls, cognitive impairment, dependence
  • If absolutely necessary, use short-acting agents at lowest effective dose for shortest duration

• Tricyclic Antidepressants (amitriptyline, imipramine, etc.)

  • Avoid due to significant anticholinergic effects and cardiovascular side effects 5, 6
  • Tertiary-amine TCAs are considered potentially inappropriate medications in the American Geriatric Society's Beers Criteria 5

• Paroxetine (Paxil)

  • Associated with more anticholinergic effects than other SSRIs 5
  • Not recommended for elderly patients

• Fluoxetine (Prozac)

  • Greater risk of agitation and overstimulation 5
  • Very long half-life which can lead to drug accumulation in elderly

Dosing Considerations for Elderly

1. Start at approximately 50% of the standard adult starting dose 5
2. Increase dose gradually (every 5-7 days) based on response and tolerability
3. Allow adequate trial period (4-8 weeks) before determining efficacy 5
4. Monitor for side effects, particularly during first few weeks of treatment
5. For escitalopram specifically, elderly patients show approximately 50% increase in half-life compared to younger adults 7

Monitoring and Follow-up

• Assess for hyponatremia, particularly with SSRIs
• Monitor for cognitive effects, sedation, and fall risk
• Evaluate for drug interactions, especially in patients taking multiple medications
• After 9-12 months, consider dose reduction to reassess continued need for medication 5

Common Side Effects to Monitor

• SSRIs: Nausea, diarrhea, headache, insomnia, sexual dysfunction
• Escitalopram specifically: Fatigue, somnolence, sleep disturbance, urinary symptoms 3
• SNRIs: Similar to SSRIs plus potential blood pressure increases
• Mirtazapine: Sedation, increased appetite, weight gain

By starting with a low dose of an SSRI (preferably sertraline or escitalopram), gradually titrating, and carefully monitoring for side effects, anxiety in elderly patients can be effectively and safely managed.
