How to reduce suicidal ideation in a patient taking escitalopram, Depakote, propranolol, and clonazepam?

Management of Suicidal Ideation in a Patient on Current Psychiatric Medications

Initiate cognitive behavioral therapy focused on suicide prevention immediately, as this is the most evidence-based intervention to reduce both suicidal ideation and suicide attempts. 1, 2

Immediate Psychotherapeutic Intervention

Cognitive behavioral therapy (CBT) focused on suicide prevention should be the primary intervention for reducing suicidal ideation in patients with a history of self-directed violence or suicidal behavior. 1, 2 The 2024 VA/DoD guidelines provide a weak recommendation for CBT-based psychotherapy (including problem-solving therapies) specifically to reduce suicidal ideation. 1

• CBT has strong evidence for reducing suicide attempts in patients with suicidal behavior within the past 6 months. 1, 2
• This intervention directly targets suicidal thoughts through cognitive restructuring and development of alternative coping strategies. 1, 2

Pharmacological Considerations

Adjunctive Ketamine Infusion

Consider adding ketamine infusion for rapid, short-term reduction of suicidal ideation if the patient has major depressive disorder. 1, 2, 3 The 2024 VA/DoD guidelines provide a weak recommendation for ketamine as an adjunctive treatment specifically for patients with suicidal ideation and major depressive disorder. 1, 4

• Ketamine provides rapid reduction in suicidal thoughts, often within 24 hours. 3, 4
• This is recommended as an adjunctive treatment, not a replacement for ongoing antidepressant therapy. 1, 2
• Evidence is insufficient to recommend ketamine for reducing actual suicide attempts, only for ideation. 1

Current Medication Review

Evaluate whether the current escitalopram dose is optimized and whether the patient has achieved adequate response. 5, 6

• Approximately 20% of patients with major depressive disorder show persistent or fluctuating suicidal ideation despite antidepressant treatment. 5
• In the STAR*D study with citalopram (same class as escitalopram), 74% of patients with baseline suicidal ideation experienced improvement by final visit, but 4% worsened. 6
• Risk factors for treatment-emergent or worsening suicidal ideation include drug abuse, severe depression, and melancholic features. 6

Consider lithium augmentation if the patient has a mood disorder (unipolar depression or bipolar disorder). 3, 7 While the 2024 VA/DoD guidelines state insufficient evidence for lithium to reduce suicide attempts, lithium maintenance therapy has historical support for reducing suicidal behaviors in mood disorders. 3, 7

Medication-Specific Cautions

• The current regimen includes clonazepam (benzodiazepine), which does not have evidence for reducing suicidal ideation and may increase impulsivity in some patients. 7
• Depakote (valproate) has some evidence as a mood stabilizer for suppression of suicidal behavior in bipolar disorder. 7
• SSRIs like escitalopram can paradoxically worsen suicidal ideation in a minority of patients through mechanisms including energizing patients to act on pre-existing ideation, inducing akathisia, or switching patients into mixed states. 8

Safety Planning and Risk Assessment

Conduct a comprehensive suicide risk assessment including the following specific domains: 1, 2

• Self-directed violence history, current suicidal thoughts with specific plans and intent
• Access to lethal means (firearms, medications, knives)
• Current psychiatric symptoms including hopelessness, agitation, impulsivity
• Social determinants: living situation, support system, recent adverse life events
• Substance abuse comorbidity
• Previous high-lethality suicide attempts
• Physical health conditions

Implement a detailed safety plan that includes: 2

• Identification of warning signs and triggers for suicidal ideation
• Specific coping strategies and healthy activities
• List of responsible social supports with contact information
• Professional support contacts with clear instructions on accessing emergency services
• Lethal means restriction counseling (securing medications, removing firearms, locking knives) 2

Note that safety planning interventions alone have insufficient evidence to reduce suicide attempts, though they remain a standard of care component. 1 A 2021 meta-analysis found safety planning reduced suicidal behavior (relative risk 0.570) but had no significant effect on suicidal ideation. 1

Follow-Up and Monitoring

Implement periodic caring communications (postal mail or text messages) for 12 months to reduce the risk of suicide attempts following any hospitalization. 1, 2 This has weak evidence support but represents a low-burden intervention. 1

Consider self-guided digital interventions with CBT-based content for short-term reduction of suicidal ideation as an adjunct to in-person therapy. 2

Reassess suicidal ideation at each follow-up using validated measures such as the Columbia Suicide Severity Rating Scale Screener or Beck Scale for Suicidal Ideation. 1, 3

Critical Timing Considerations

• The greatest risk for a new suicide attempt occurs in the months following an initial attempt. 2
• Approximately 24% of suicide attempts are implemented within 0-5 minutes of deciding, highlighting the impulsive nature and importance of lethal means restriction. 2
• Patients who persist in endorsing a desire to die, remain agitated or hopeless, cannot participate in safety planning, or lack adequate support should be considered for psychiatric hospitalization. 2

Interventions with Insufficient Evidence

Dialectical behavior therapy (DBT), while combining CBT elements with skills training, has insufficient evidence to recommend for or against its use for reducing suicidal ideation. 1, 2

Collaborative Assessment and Management of Suicidality (CAMS) has insufficient evidence for reducing suicidal ideation. 1
