Identify one scenario where the use of combination therapy for antidepressants may be warranted.

• A. Mild depressive episodes
• B. Seasonal Affective Disorder
• C. Treatment-resistant depression
• D. Generalized anxiety disorder

Answer: (C)

The use of combination therapy for antidepressants is particularly warranted in the context of treatment-resistant depression. This scenario typically involves patients who have not responded adequately to first-line treatment options, such as selective serotonin reuptake inhibitors (SSRIs) or other single-agent antidepressants. In many cases, treatment-resistant depression manifests as a persistent or recurring depressive episode despite adequate trials of several medications. Combining different classes of antidepressants can enhance efficacy through various mechanisms. For instance, using a combination of an SSRI and a norepinephrine-dopamine reuptake inhibitor (NDRI) can target multiple neurotransmitter systems simultaneously, potentially leading to improved mood and reduced symptoms. This approach can be beneficial for patients who have specific symptom profiles or comorbidities that single agents do not adequately address. In contrast, mild depressive episodes and seasonal affective disorder typically respond well to monotherapy, and generalized anxiety disorder may often be managed effectively with anxiolytic treatments or selective antidepressants alone. Hence, combination therapy is primarily explored in those with more severe, treatment-resistant cases where a more robust intervention is necessary to achieve symptom relief.
