Leukocytosis after Clozapine Treatment in a Patient with Chronic Schizophrenia.

Clozapine is an atypical antipsychotic drug that is approved by the US Food and Drug Administration (FDA) for the treatment of psychotic disorders. Agranulocytosis is a well-established side effect of clozapine; clozapine has also been associated with other blood dyscrasias like leukocytosis, albeit rarely. In this paper, we aim to report a case of possible clozapine-associated leukocytosis in a 41-year-old woman.
