A 32-year-old woman presents to the outpatient clinic with a 2-month history of severely depressed mood. She reports sleeping up to 14 hours a day, an increased appetite with a 5-kg (11-lb) weight gain, and a frequent sensation that her arms and legs are "made of lead." She states that she briefly feels better when her friends visit, but her low mood quickly returns. She has no prior psychiatric history and has never been treated for depression. She tearfully requests an antidepressant medication so she can return to her job as an accountant. Her vital signs and physical examination are unremarkable. Laboratory studies reveal a thyroid-stimulating hormone (TSH) level of 1.5 mU/L (normal: 0.4-4.0 mU/L) and a free T4 at the lower limit of normal. A urine toxicology screen is negative. The physician diagnoses a major depressive episode with atypical features and considers initiating pharmacotherapy. Which of the following is the most appropriate next step in management?
- Elicit a history of periods of elevated mood, impulsivity, and decreased need for sleepCevap
- BInitiate sertraline monotherapy and plan to discontinue the medication 2 weeks after symptom remission
- CInitiate fluoxetine and phenelzine concurrently to aggressively target her atypical depressive features
- DDelay pharmacotherapy and recommend psychotherapy, as symptom duration must exceed 6 months for a diagnosis
- EInitiate levothyroxine therapy, as her atypical symptoms are caused by primary hypothyroidism
