Which medication is used for severely suicidal patients due to monitoring requirements?

• A. Fluoxetine
• B. Sertraline
• C. Paroxetine
• D. Clozapine

Answer: (D)

Clozapine is used for severely suicidal patients because, in addition to its antipsychotic effects, it has a proven ability to reduce suicidality in treatment-resistant schizophrenia. But its use carries a serious risk of agranulocytosis, so it requires ongoing, regular monitoring of white blood cell and neutrophil counts. This monitoring typically starts with frequent checks and becomes less frequent as stability is established. Because of this need for strict hematologic surveillance, clozapine is chosen when suicidality is a major concern and other treatments have not adequately controlled symptoms. Other antidepressants like fluoxetine, sertraline, or paroxetine can help with mood and suicidal thoughts, but they do not demand such intensive blood monitoring and aren’t selected specifically for severe suicidality based on monitoring requirements.
