What is the best anti‑anxiety medication for a 76‑year‑old woman who has been taking temazepam chronically?

Transition to an SSRI or SNRI for Long-Term Anxiety Management

For a 76-year-old woman on chronic temazepam, the best anti-anxiety medication is an SSRI (such as escitalopram, citalopram, or sertraline) or SNRI (such as venlafaxine or duloxetine), while carefully tapering the benzodiazepine under close supervision. 1, 2

Why Benzodiazepines Are Problematic in This Patient

The 2019 American Geriatrics Society Beers Criteria explicitly warns against benzodiazepines in older adults due to:

• Substantially increased risk of falls and fractures with larger doses in elderly patients 2, 3
• Cognitive impairment and delirium 2, 4
• Physical dependence with protracted withdrawal syndrome lasting weeks to over 12 months 3
• Tolerance, addiction, and paradoxical agitation in ~10% of patients 1

Critical pitfall: Long-term benzodiazepine use (which this patient has) creates physical dependence requiring slow, supervised tapering—abrupt discontinuation can cause seizures, severe mental status changes, and life-threatening withdrawal 3.

First-Line Pharmacotherapy for Anxiety in Older Adults

SSRIs (Preferred Initial Choice)

Escitalopram, citalopram, or sertraline are specifically recommended for elderly patients with anxiety 5. These agents:

• Treat generalized anxiety, panic disorder, and social anxiety effectively 6
• Have favorable side effect profiles in older adults 5
• Address comorbid depression (present in many elderly anxiety patients) 1, 7

Avoid: Paroxetine and fluoxetine in elderly due to higher adverse effect rates 5

Dosing strategy: Start at subtherapeutic doses to avoid initial anxiety exacerbation, then titrate slowly over 1-2 weeks for shorter half-life SSRIs 8. Expect 4-8 weeks for full therapeutic effect 1.

SNRIs (Alternative First-Line)

Venlafaxine or duloxetine can be considered, though they carry slightly higher discontinuation rates due to nausea/vomiting compared to SSRIs 5. Monitor blood pressure, as SNRIs can cause sustained hypertension 8.

Buspirone (Non-Benzodiazepine Option)

Buspirone 5-30 mg/day is effective and well-tolerated in elderly patients with anxiety, including those on multiple medications for chronic conditions 9. However, it requires 2-4 weeks to become effective and works best for mild-to-moderate anxiety 1.

Practical Transition Algorithm

1. Initiate SSRI/SNRI at low dose while patient remains on current temazepam dose
2. Titrate antidepressant to therapeutic range over 4-8 weeks
3. Begin slow benzodiazepine taper only after antidepressant reaches therapeutic effect—reduce temazepam by no more than 10-25% every 1-2 weeks 10, 11
4. Monitor closely for withdrawal symptoms (anxiety, insomnia, tremor, confusion) and falls risk 3

Cognitive behavioral therapy should be added if available, as it facilitates benzodiazepine discontinuation and provides durable anxiety reduction 10.

What NOT to Use

• Trazodone: Not recommended for insomnia despite common off-label use; carries significant risks in elderly 12, 13
• Antihistamines (diphenhydramine): Not recommended due to lack of efficacy/safety data and anticholinergic effects 10, 12
• Continuing temazepam long-term: Chronic benzodiazepine use should be discouraged given dependence risk and serious medical complications in elderly 4

Special Monitoring Considerations

• Falls risk assessment: Temazepam 7.5 mg is the maximum recommended dose in patients ≥65 years due to oversedation, dizziness, confusion, and ataxia 3
• Renal function: If eGFR <30 mL/min, avoid morphine-based medications if opioids are co-prescribed; adjust doses accordingly 14
• Drug interactions: Check for CYP450 interactions, particularly with cimetidine and other medications common in elderly patients 3

The goal is complete benzodiazepine discontinuation with transition to safer long-term anxiety management, recognizing this may take 3-6 months of careful tapering 10, 11.
