Neutropenia and Thrombocytopenia Induced By Quetiapine Monotherapy: A Case Report and Review of Literature

Abstract: Neutropenia and thrombocytopenia induced by quetiapine monotherapy: a case report and review of literature Antipsychotic drugs can cause neutropenia which can progress to life-threatening agranulocytosis. Clozapine is well-known for this side effect which is rare for other antipsychotics. Quetiapine is a newer atypical antipsychotic which shows similarities with clozapine in chemical structure. We present a rare case of neutropenia and thrombocytopenia induced by quetiapine monotherapy of 600 mg/day in a 69-ye… Show more

“…In patients with schizophrenia, quetiapine (600-1,200 mg/day, case reports) is associated with neutropenia, leukopenia (236-239), agranulocytosis, and thrombocytopenia (240). The mechanism by which quetiapine causes these adverse effects is still unclear, but some authors have proposed that this drug acts directly as a cytotoxic agent on immune cells, thus producing cell death; additionally, some products of quetiapine oxidation could induce apoptosis by oxidative stress (241). Other authors have suggested a bone marrow depression by quetiapine consumption, which could be produced by an inhibitory effect on leukopoiesis.…”

Patient’s hematological and biochemical parameters were in normal range before quetiapine treatment.…”
