Monitor ANC weekly for 26 weeks, biweekly for 26 weeks, then monthly. This describes which monitoring protocol?

• A. Clozapine monitoring
• B. FGAs dosing
• C. Efficacy correlation
• D. EPS

Answer: (A)

Clozapine requires regular monitoring of the absolute neutrophil count because of the risk of agranulocytosis. The pattern starts with frequent checks—weekly for about six months (roughly 26 weeks), then every two weeks for another six months (the next 26 weeks), and once stability is established, monthly checks. This specific schedule is designed to catch dangerous neutropenia early while allowing continued treatment when ANC remains normal. Other options don’t fit because standard antipsychotics don’t require this ANC monitoring, extrapyramidal symptoms are a side effect rather than a monitoring protocol, and “efficacy correlation” isn’t a monitoring schedule.
