Which medication is used as adjunct to mood stabilizers/antidepressants for schizoaffective disorder?

• A. Ziprasidone
• B. Clozapine
• C. Paliperidone
• D. Quetiapine

Answer: (C)

In schizoaffective disorder, treatment aims to control psychotic symptoms while also addressing mood symptoms, so clinicians often add an antipsychotic to ongoing mood stabilizers or antidepressants. Paliperidone fits well as an adjunct because it is an effective atypical antipsychotic that targets the psychotic features (positive symptoms) and has evidence supporting its use alongside mood-stabilizing or antidepressant therapy in this condition. Its pharmacology—D2 and 5-HT2A antagonism—helps reduce psychosis and can indirectly support mood stabilization during concurrent mood-directed treatment. Additionally, its dosing options, including a once-daily form (and a long-acting injectable variant), can improve adherence, a key factor in managing schizoaffective disorder. While other antipsychotics can be used, paliperidone has stronger evidence and guideline support for augmentation in this specific clinical scenario, making it a preferred adjunct.
