Abstract

Clozapine is a well-known antipsychotic which causes hematologic adverse effects, specifically neutropenia and agranulocytosis (1-3% of patients). However, reports on blood dyscrasias like anemia and thrombocytosis after clozapine treatment are extremely rare. In some cases re-challenge of clozapine could lead to hematopoietic abnormality related to thrombocytopenia or thrombocytosis, which may be a result of an immune reaction. This case report suggests that clinicians should monitor platelet count after re-treatment with clozapine.
