How can I improve depression and crying spells in an 87-year-old woman with depression and anxiety who is on duloxetine 20 mg daily and alprazolam?

Optimizing Treatment for Depression and Crying Spells in an 87-Year-Old Woman

Increase duloxetine to 60 mg daily, as the current 20 mg dose is substantially below the therapeutic range for depression and anxiety, and taper alprazolam to discontinuation while monitoring closely for withdrawal symptoms and fall risk.

Current Medication Assessment

Duloxetine Underdosing

• The FDA-approved starting dose for major depressive disorder is 40 mg daily (20 mg twice daily) to 60 mg daily, with 60 mg once daily being the recommended therapeutic dose 1
• Your patient is receiving only 20 mg daily—one-third of the minimum recommended starting dose—which explains the persistent crying spells and inadequate symptom control 1
• For geriatric patients with generalized anxiety disorder, the FDA recommends initiating at 30 mg once daily for 2 weeks before increasing to the target dose of 60 mg daily 1
• Approximately 38% of patients fail to achieve response at subtherapeutic SSRI/SNRI doses within 6-12 weeks, and 54% do not achieve remission 2

Alprazolam Concerns in Elderly Patients

• Benzodiazepines like alprazolam should be avoided in geriatric patients due to increased risk of cognitive impairment, falls, and paradoxical disinhibition that can worsen depression 2
• Alprazolam may reduce self-control and disinhibit some individuals, potentially leading to worsening mood symptoms 2
• The combination of benzodiazepines with antidepressants in elderly patients increases polypharmacy risks and drug-drug interactions 3

Recommended Treatment Algorithm

Week 1-2: Duloxetine Dose Escalation

• Increase duloxetine from 20 mg to 30 mg once daily for one week to allow gradual adjustment and minimize treatment-emergent nausea, which is the most common adverse effect 3, 1
• After one week at 30 mg, increase to 60 mg once daily, which is the target therapeutic dose for depression and anxiety in adults 1, 4
• Administer duloxetine with or without meals, swallowed whole without crushing or opening the capsule 1

Week 2-4: Alprazolam Taper

• Once duloxetine reaches 60 mg daily, begin a gradual alprazolam taper over 2-4 weeks to minimize withdrawal symptoms including rebound anxiety, insomnia, and tremor 2
• Monitor weekly for benzodiazepine withdrawal symptoms: anxiety, agitation, tremor, insomnia, and perceptual disturbances 2

Week 4-8: Response Assessment

• Allow 6-8 weeks at duloxetine 60 mg daily before evaluating full therapeutic response, as most patients achieve adequate response by 4-6 weeks at this dose 3
• Monitor for improvement in crying spells, depressed mood, anxiety symptoms, and functional impairment using standardized measures 2
• Assess for treatment-emergent adverse effects: nausea (most common), dry mouth, constipation, dizziness, and fatigue 3, 4

Safety Monitoring in Geriatric Patients

Critical Monitoring Parameters

• Check blood pressure at each visit, as duloxetine can increase systolic and diastolic blood pressure and heart rate, particularly when combined with other medications 3
• Monitor for falls risk, especially during the first 2-4 weeks when transitioning off alprazolam and adjusting to higher duloxetine doses 3
• Assess liver function before initiating dose escalation, as duloxetine carries rare risk of hepatotoxicity 3
• Screen for suicidality at weeks 1,2,4, and 8, although risk is lower in geriatric patients than in younger adults 2

Cardiovascular Considerations

• Duloxetine has a favorable cardiovascular profile with no clinically important ECG changes or significant blood pressure alterations in most patients 3
• However, use caution in patients with uncontrolled hypertension or underlying coronary artery disease 3

If Inadequate Response After 8 Weeks

Dose Escalation Strategy

• If crying spells and depression persist after 8 weeks at duloxetine 60 mg daily, consider increasing to 90 mg daily (30 mg increments), allowing 1-2 weeks at each dose level 3
• The maximum FDA-approved dose is 120 mg daily, though there is no evidence that doses greater than 60 mg confer additional benefit for depression in most patients 1
• In geriatric patients, cautious dose escalation with small increments at intervals allowing adequate observation (at least one week at each dose level) is recommended 3

Alternative Strategies

• Add cognitive behavioral therapy (CBT) or interpersonal therapy, as combination treatment is superior to medication alone for depression with anxiety 2
• If no response after 8 weeks at 120 mg daily, switch to a different SSRI (sertraline 50-200 mg daily or escitalopram 10-20 mg daily) rather than further duloxetine dose increases 2, 3
• Venlafaxine extended-release 75-225 mg daily may have statistically better response rates than SSRIs specifically for depression with prominent anxiety symptoms 2

Treatment Duration

• Continue duloxetine for a minimum of 4-9 months after satisfactory response for first-episode depression 2
• Consider longer duration (≥1 year) for patients with recurrent episodes, as discontinuation of effective antidepressant treatment commonly leads to relapse—26-52% of patients relapse when medication is discontinued 2
• After a first episode, recurrence probability is 50%; after two episodes it increases to 70% 2

Common Pitfalls to Avoid

• Do not discontinue duloxetine abruptly—taper gradually over at least 2-4 weeks to prevent withdrawal symptoms including nausea, dizziness, adrenergic hyperactivity, and anxiety 3
• Do not assume crying spells represent treatment failure at 20 mg—this dose is far below the therapeutic range and dose optimization is the appropriate first step 1
• Do not continue alprazolam long-term in geriatric patients—benzodiazepines worsen cognitive function and increase fall risk, and SSRIs/SNRIs provide superior long-term anxiety control 2
• Do not switch medications prematurely—allow full 6-8 weeks at therapeutic duloxetine doses (60 mg daily minimum) before concluding treatment failure 2, 3
