description Summary Clozapine, an atypical antipsychotic drug, is associated with a high risk of neutropenia and agranulocytosis, necessitating the immediate discontinuation of the drug. We report the case of a patient who developed clozapine-induced neutropenia. Assessments revealed a pronounced diurnal variation in the number of circulating neutrophils (1200-1900 mm3 in the morning and 2200- 2700 mm3 in the afternoon). Due to these circadian changes, we decided to continue clozapine treatment.
