A 34-year-old man comes to the primary care clinic complaining of dizziness, nausea, vivid nightmares, and "electric shock-like" sensations in his head for the past 3 days. He has a history of major depressive disorder, which has been well-controlled on paroxetine for the past year. During the interview, he mentions that he felt completely back to normal, so he abruptly stopped taking his medication 4 days ago. His vital signs and physical examination are unremarkable. Which of the following is the most appropriate next step in management?
- Restart paroxetine and initiate a gradual tapering scheduleCevap
- BPrescribe a monoamine oxidase inhibitor, such as phenelzine, to replace the paroxetine
- CInitiate a mood stabilizer, such as valproic acid, to prevent a manic switch
- DAdmit the patient for acute management of brief psychotic disorder
- EPrescribe a short course of broad-spectrum antibiotics for a possible infectious etiology
Cevap
Restart paroxetine and initiate a gradual tapering schedule.
The correct action is to restart paroxetine and initiate a gradual tapering schedule. This patient is experiencing antidepressant discontinuation syndrome. This syndrome typically occurs within a few days of abruptly stopping a selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI). It is particularly common with medications that have a short half-life and no active metabolites, such as paroxetine and venlafaxine. Classic symptoms include flu-like symptoms, insomnia, nausea, imbalance, sensory disturbances (often described as 'brain zaps' or electric shock-like sensations), and hyperarousal. The definitive treatment is to restart the discontinued medication, which usually resolves symptoms within 24 hours, followed by a gradual dose taper if the patient still wishes to discontinue the drug.
