WHEN TO SWITCH VERSUS AUGMENT PHARMACOTHERAPIES
Determining when to switch versus augment pharmacotherapy is a central challenge in the treatment of psychiatric disorders, including major depressive disorder. Clinicians must balance symptom severity, treatment history, side-effect burden, and functional impairment while navigating an expanding evidence base and evolving clinical guidelines. Switching may be preferred when patients experience intolerable adverse effects, lack of response or only partial response, and clear mechanistic mismatch with the underlying disorder. Augmentation strategies can be highly effective when partial but inadequate improvement is observed, or continuation of background treatment is clinically indicated. The decision is further influenced by comorbidities, patient preferences, pharmacokinetic considerations, and the risk-benefit profile of potential adjunctive agents. Understanding the nuances that guide switching versus augmentation is therefore essential for optimizing outcomes across major psychiatric disorders and their complex presentations. This presentation will also focus on shared decision-making approaches that can be utilized to make the decision of switch versus augment.
