Case Introduction

John* is a 25-year-old African American man who works for a graphic design company. He has worked for the company for the past 3 years and was promoted to project manager 6 months ago.

John was diagnosed with bipolar disorder 5 years ago after experiencing a manic episode during summer break in college. During this episode, John exhibited symptoms of (1) euphoria (which led to a period of time in which he did not sleep for more than 3 hours per night), (2) impulsivity (which manifested in a spur-of-the-moment trip to Las Vegas with some members of his fraternity, where he lost $400 at a casino), and (3) distractibility (during which time he frequently “lost track of time” and forgot to go to his summer job, resulting in his termination).1 He had previously been referred to a psychiatrist when he was 18 years old for a depressive episode that lasted 3 months. At that appointment, John reported that his father had struggled with bipolar disorder his entire life, which had ultimately led to periods of unemployment and disruptions, both financial and emotional, and a decreased quality of life for the rest of the family.

John’s treating psychiatrist resolved this manic episode with 1500 mg/d of lithium2 and 5 mg/d of haloperidol.3 Guidelines suggest lithium4 as initial treatment for patients diagnosed with bipolar disorder, and haloperidol has shown efficacy in reducing symptoms of mania when compared to second-generation antipsychotics (SGAs).5 For long-term maintenance treatment, the dosages were decreased to 1000 mg/d of lithium and 2 mg/d of haloperidol.

Patient Presentation

John’s promotion was accompanied by relocation to a new city, and he was referred to you by his previous treating psychiatrist. He has been on his current treatment regimen for 5 years. John presents to you with no complaints about his treatment, but you notice some mild pursing movements of his lips and choreiform movements of his hands. When you inquire about these movements, John states that he has been stressed lately due to the move and new job, and he assumed that they would go away in time.

You administer the Abnormal Involuntary Movement Scale (AIMS) and discover that John scores a 2 in both the “Facial and Oral Movements” and “Extremity Movements” categories, which indicates mild symptom severity of tardive dyskinesia (TD).

Given his treatment history, what is the best next treatment step for John?

  1. Discontinue haloperidol and switch to an SGA
  2. Decrease lithium to 500 mg/d
  3. Decrease haloperidol dosage to 0.5 mg/d
  4. Discontinue lithium and begin treatment with a selective serotonin reuptake inhibitor (SSRI)

Explanation

The correct answer is a. Discontinue haloperidol and switch to an SGA.

Patients who are treated with long-term haloperidol may be at a higher risk for developing TD symptoms than those taking SGAs.1 Decreasing haloperidol to 0.5 mg/d is an incorrect response because clinicians should discontinue first-generation antipsychotic (FGA) treatment when TD symptoms occur, rather than decrease dosage.2 Because John has been taking this medication for 5 years and is African American, his risk of developing TD symptoms may be elevated.3 Additional risk factors that can increase a patient’s chance of developing TD symptoms are older age, female sex, preexisting mood disorder, cognitive disturbance, alcohol or substance abuse, diabetes, HIV positivity, and the early occurrence of extrapyramidal side effects.4

Decreasing lithium to 500 mg/d is incorrect because it falls below the recommended dosage of 900 mg/d, and lithium is not associated with an increased risk of TD.5 Discontinuing lithium and beginning treatment with an SSRI is also incorrect, as lithium has shown some efficacy in protecting against TD symptoms during long-term antipsychotic treatment.6 Additionally, research suggests that in patients diagnosed with bipolar disorder, antidepressants may trigger a manic episode.7

You discontinue haloperidol and replace it with 10 mg/d of aripiprazole, and you add 50 mg of pyridoxine twice daily because vitamin B6 has shown efficacy in reducing TD symptoms.8 As a result, John’s dyskinesia symptoms resolve substantially.
