Management of Bipolar Disorder Patient on Lexapro and Abilify

The patient with bipolar disorder should be transitioned off escitalopram (Lexapro) and placed on a proper mood stabilizer with aripiprazole (Abilify), as antidepressants should only be used in combination with mood stabilizers for bipolar depression. 1

Current Medication Issues

The current medication regimen presents several concerns:

  1. Escitalopram (Lexapro) monotherapy is not recommended for bipolar disorder as it can:

    • Trigger manic episodes
    • Worsen mood cycling
    • Destabilize the overall course of bipolar disorder

  2. While aripiprazole (Abilify) has been added, this combination is problematic because:

    • Aripiprazole is effective for acute mania and maintenance treatment to prevent manic episodes 2, 3
    • However, aripiprazole has limited efficacy for bipolar depression 3, 4
    • The combination lacks a proper mood stabilizer foundation

Recommended Treatment Approach

Step 1: Add a Mood Stabilizer

  • Initiate one of the following mood stabilizers:
    • Lithium (first-line classic mood stabilizer with strong evidence) 1
    • Valproate (53% response rate in bipolar disorder) 1
    • Consider lamotrigine for patients with predominantly depressive episodes

Step 2: Gradually Taper Escitalopram

  • Once the mood stabilizer reaches therapeutic levels, begin tapering escitalopram
  • Slow taper (e.g., 5mg reduction every 1-2 weeks) to minimize withdrawal symptoms
  • Monitor closely for emergence of depressive symptoms during taper

Step 3: Optimize Aripiprazole

  • Continue aripiprazole 5mg as it can help prevent manic episodes 1, 2
  • Consider dose adjustment based on response and tolerability
  • Note that aripiprazole is more effective for preventing manic episodes than depressive episodes 3

Step 4: Consider Alternative Treatments if Needed

  • If depression persists after optimizing mood stabilizer and aripiprazole:
    • Consider olanzapine-fluoxetine combination (ranked highest for bipolar depression) 4
    • Quetiapine or lurasidone are also effective options for bipolar depression 4

Monitoring Recommendations

  • Regular laboratory monitoring based on chosen therapy 1:

    • Mood stabilizer serum levels
    • Thyroid function
    • Renal and liver function
    • CBC, pregnancy tests (if applicable)
    • Weight, BMI, blood pressure
    • Fasting glucose and lipid panel

  • Monitor for signs of mood switching:

    • Increased energy, decreased need for sleep
    • Racing thoughts, pressured speech
    • Impulsivity or risk-taking behaviors

Important Considerations

  • The combination of aripiprazole with mood stabilizers is more effective than monotherapy for bipolar disorder 2
  • Aripiprazole-valproate combination may be particularly beneficial for patients with comorbid anxiety 2
  • Treatment adherence is critical, as over 50% of bipolar patients are non-adherent 1
  • Psychoeducation and cognitive behavioral therapy should be offered alongside medication 1

Common Pitfalls to Avoid

  • Continuing antidepressant monotherapy in bipolar disorder
  • Failing to add a mood stabilizer as the foundation of treatment
  • Inadequate monitoring for mood switching
  • Premature discontinuation of maintenance therapy (should continue for at least 2 years after the last episode) 1
  • Rapid medication changes that can destabilize mood
