What is the best approach to simplify a psychotropic medication regimen for a patient with MDD and GAD, taking multiple medications, with a history of non-adherence and complex medical history?

Psychotropic Medication Simplification Plan

Direct Recommendation

Begin by discontinuing olanzapine first, as it is the most recent addition (started >1 year ago for irritability), has significant metabolic and orthostatic risks in this patient with diabetes, obesity, hypotension (BP 102/60), and falls, and the patient's current PHQ-9 (10) and GAD-7 (7) scores indicate only mild-moderate symptoms despite reduced life stress. 1

Stepwise Medication Management Plan

Step 1: Discontinue Olanzapine (Weeks 1-4)

Rationale for removing first:

• Olanzapine was added adjunctively for irritability after duloxetine and buspirone were already established 1
• When multiple medications target overlapping symptoms, remove the adjunctive agent first 1
• The patient reports significantly reduced stress post-retirement, suggesting the indication (persistent irritability) may have resolved 1
• Olanzapine contributes to orthostatic hypotension (BP 102/60), falls, metabolic dysregulation (blood sugars 40s-400s), and weight gain (BMI 37.6) 1

Tapering schedule:

• Reduce olanzapine by 25-50% every 1-2 weeks to avoid rebound symptoms 1
• If currently on 5mg: reduce to 2.5mg for 2 weeks, then discontinue
• If currently on 10mg: reduce to 5mg for 2 weeks, then 2.5mg for 2 weeks, then discontinue 1

Monitoring during weeks 1-4:

• Assess irritability, mood stability, and sleep weekly using PHQ-9 and GAD-7 2
• Monitor for rebound agitation or mood destabilization 1
• Track blood pressure and fall frequency 1

Step 2: Discontinue Clonazepam (Weeks 5-8)

Rationale:

• Patient uses clonazepam only once every few weeks, indicating minimal current dependence 2
• Benzodiazepines significantly increase fall risk, especially with concurrent orthostatic hypotension and neuropathy 1, 3
• Buspirone was specifically added to reduce clonazepam use, and this goal has been achieved 2
• The patient's GAD-7 score of 7 (mild anxiety) does not justify ongoing benzodiazepine use 2

Tapering schedule:

• If using 0.5mg as needed: reduce to 0.25mg as needed for 2 weeks, then discontinue 1
• Gradual tapering prevents benzodiazepine withdrawal symptoms (anxiety, insomnia, seizures) 1

Monitoring during weeks 5-8:

• Assess anxiety symptoms and panic frequency using GAD-7 every 2 weeks 2
• Monitor for benzodiazepine withdrawal (tremor, increased anxiety, insomnia) 1
• Continue tracking falls and blood pressure 1

Step 3: Consolidate Amitriptyline Dosing (Weeks 9-12)

Rationale:

• Patient reports missing doses at least weekly, indicating regimen complexity is a barrier 4, 5, 3
• Amitriptyline for sleep and pain can be given as a single nighttime dose 6, 4
• Simplifying to once-daily nighttime dosing improves adherence without compromising efficacy 6, 4
• Amitriptyline contributes to orthostatic hypotension and anticholinergic burden in elderly patients with CKD stage III 1

Consolidation plan:

• Convert all amitriptyline to single nighttime dosing 6, 4
• If sedation persists in morning, reduce total daily dose by 25% 6
• Consider switching to gabapentin dose optimization for neuropathic pain if amitriptyline side effects remain problematic 1

Monitoring during weeks 9-12:

• Assess pain control, sleep quality, and morning sedation weekly 6
• Monitor for worsening orthostatic symptoms and falls 1
• Evaluate adherence improvement with simplified regimen 4, 5

Step 4: Optimize Duloxetine and Buspirone (Weeks 13-16)

Rationale for keeping both:

• Duloxetine was started >5 years ago and "helped," indicating established efficacy 7
• Duloxetine addresses both depression and anxiety (dual indication) and neuropathic pain 7
• Buspirone successfully reduced clonazepam dependence and targets residual anxiety 2
• Current PHQ-9 (10) and GAD-7 (7) indicate partial response, not treatment failure 1, 2

Optimization plan:

• Keep duloxetine at current dose (likely 30-60mg daily based on history of dose reduction for hypertension) 7
• Do not increase duloxetine above 60mg daily, as doses >60mg show no additional benefit for GAD or depression 7
• Keep buspirone at current dose for ongoing anxiety management 2
• Consolidate duloxetine to once-daily dosing if currently split 7, 4

Monitoring during weeks 13-16:

• Reassess PHQ-9 and GAD-7 at week 16 to establish new baseline after medication simplification 2
• Monitor blood pressure (may improve after olanzapine discontinuation) 1
• Assess overall adherence and patient satisfaction with simplified regimen 4, 5

Medications to KEEP

Duloxetine:

• Established efficacy for MDD, GAD, and neuropathic pain over 5+ years 7
• Addresses multiple target symptoms with single agent 7
• Dose of 60mg daily is optimal; higher doses offer no additional benefit 7

Buspirone:

• Successfully reduced benzodiazepine dependence (primary goal achieved) 2
• Provides ongoing anxiety management without addiction or fall risk 2
• Well-tolerated in patients with medical comorbidities 2

---

Medications to DISCONTINUE

Olanzapine (first):

• Adjunctive agent for symptom (irritability) that may have resolved with life stress reduction 1
• Significant contributor to metabolic dysfunction, orthostatic hypotension, and falls 1

Clonazepam (second):

• Minimal current use (once every few weeks) indicates successful transition to buspirone 2
• High fall risk in patient with orthostatic hypotension and neuropathy 1, 3

---

Critical Monitoring Parameters

Throughout 16-week simplification period:

• PHQ-9 and GAD-7 every 2-4 weeks to detect symptom worsening 2
• Blood pressure at each visit (expect improvement after olanzapine discontinuation) 1
• Fall frequency and orthostatic symptoms weekly 1
• Blood glucose control (expect improvement after olanzapine discontinuation) 1
• Medication adherence assessment at each visit 4, 5
• Suicidal ideation screening at each visit (patient currently denies SI/HI) 2

Common Pitfalls to Avoid

Do not discontinue medications too rapidly:

• Gradual tapering over weeks prevents withdrawal and rebound symptoms 1
• Olanzapine and benzodiazepines require slow tapers to avoid destabilization 1

Do not remove multiple medications simultaneously:

• Discontinue one medication at a time with 4-week intervals to identify cause of any symptom changes 1
• Sequential approach allows clear attribution of benefits or adverse effects 1

Do not assume age alone predicts non-adherence:

• Regimen complexity, not age, is the primary adherence barrier in this patient 4, 8
• Simplification strategies (once-daily dosing, reducing pill burden) directly address the patient's reported adherence problems 6, 4

Do not discontinue duloxetine despite past dose reduction:

• The dose was reduced for hypertension management, not lack of efficacy 7
• Current blood pressure (102/60) is now LOW, not high, indicating the cardiovascular concern has resolved 1
• Duloxetine remains the foundational treatment for this patient's MDD, GAD, and neuropathic pain 7
