Late-onset clozapine-induced neutropenia treated with lithium

Özet

Clozapine is a second-generation antipsychotic drug, proven to be effective in treatment-resistant schizophrenia. Among patients using clozapine; the incidence of neutropenia is approximately 3% and the incidence of agranulocytosis is approximately 1%. This side effect is diminishing after 18 weeks of drug initiation. Here, we present a case of clozapine-induced neutropenia in a schizophrenic patient seen after 7 years of clozapine use and its treatment with lithium supplementation.
