Which medication is indicated for treatment-resistant schizophrenia?

• A. Paliperidone
• B. Clozapine
• C. Risperidone
• D. Olanzapine

Answer: (B)

In treatment-resistant schizophrenia, the key idea is that some patients do not respond to standard antipsychotics despite adequate trials. Clozapine is indicated in this scenario because it has demonstrated superior efficacy for those who have not responded to at least two other antipsychotics, making it the go-to option when conventional treatments fail. It also offers benefits in reducing suicidality in schizophrenia. The other antipsychotics listed can help many patients with schizophrenia, but they do not have the same proven effectiveness in treatment-resistant cases, and they are typically tried before moving to clozapine. Clozapine’s advantage comes with a notable need for careful monitoring due to the risk of agranulocytosis, so it requires baseline and regular blood tests (including absolute neutrophil counts) and ongoing safety checks.
