Which drug is used for treatment-resistant schizophrenia?

• A. Chlopromazine
• B. Valium
• C. Benadryl
• D. Clozaril

Answer: (D)

Clozapine is used for treatment-resistant schizophrenia because it has demonstrated meaningful efficacy in patients who do not respond to at least two other antipsychotics at adequate doses and durations. It can reduce psychotic symptoms when other medications fail and also lowers suicidality risk in schizophrenia. Because of its serious potential side effects, clozapine requires careful, ongoing monitoring (such as regular ANC blood tests and enrollment in a monitoring program) and is typically reserved for those who have not responded to other antipsychotics. The other drugs listed are not appropriate for treatment-resistant schizophrenia. Chlorpromazine is a first-generation antipsychotic that can help some patients but isn’t specifically indicated for TRS and carries substantial movement disorder risks. Valium is a benzodiazepine used for anxiety or agitation, not to treat the core psychosis. Benadryl is an antihistamine with anticholinergic effects and does not treat schizophrenia; it might be used temporarily to manage certain side effects but not as a primary treatment for resistant psychosis.
