Best Medication for a 70-Year-Old Woman with GAD Score of 15 and Mild Depression

Escitalopram (10 mg daily) is the recommended first-line medication for this elderly patient with severe anxiety (GAD-7 score of 15) and mild depression due to its efficacy, favorable side effect profile, and appropriate dosing for geriatric patients. 1

Assessment of Patient's Condition

• A GAD-7 score of 15 indicates severe levels of anxiety according to standardized assessment scales 2
• The patient also has mild depression, which commonly co-occurs with generalized anxiety disorder 3
• Age (70 years) is an important consideration for medication selection due to potential side effects and drug interactions in elderly patients 4, 5

Medication Recommendations

First-Line Treatment: Escitalopram

• Start with escitalopram 10 mg once daily (morning or evening, with or without food) 1
• 10 mg/day is specifically recommended for elderly patients and should be maintained without dose escalation initially 1
• Benefits of escitalopram in this case:
  • FDA-approved for both GAD and depression 1
  • Lower potential for drug interactions compared to some other SSRIs 5
  • No dosage adjustment needed based solely on age 1
  • Once-daily dosing improves adherence 1

Alternative Option: Sertraline

• If escitalopram is not tolerated or ineffective, sertraline (50-100 mg/day) is an appropriate alternative 4, 6
• Benefits of sertraline:
  • Demonstrated efficacy for both depression and anxiety in elderly patients 4, 6
  • Low potential for drug interactions via cytochrome P450 system 5
  • Well-tolerated in elderly patients with fewer anticholinergic effects than tricyclic antidepressants 4

Monitoring and Follow-up

• Evaluate response after 4 weeks of treatment 1
• If partial response but inadequate improvement, consider:
  • For escitalopram: May increase to 20 mg daily after minimum of one week at 10 mg (though 10 mg is often sufficient) 1
  • For sertraline: May titrate up to 150 mg daily if needed and tolerated 4
• Monitor for side effects, particularly in the first few weeks of treatment 1

Important Considerations for Elderly Patients

• Screen for bipolar disorder before initiating treatment to avoid precipitating mania 1
• Check for potential drug interactions with current medications 5
• Start at lower doses and titrate more slowly than in younger adults 1
• Monitor for common SSRI side effects: nausea, headache, insomnia, dizziness 4
• Avoid abrupt discontinuation; taper gradually if discontinuing 1

Treatment Duration

• For GAD: Efficacy beyond 8 weeks has not been systematically studied, but long-term treatment is often needed 1
• For depression: Several months of treatment beyond acute response is generally recommended 1
• Periodically reassess the need for continued treatment 1
