Haloperidol induced neutropenia

Abstract EN

Leukopenia, neutropenia and agranulocytosis (low white blood cells count) are rare but serious side effects of antipsychotics, notably clozapine.

We here report a case of an Afro-Caribbean patient who developed neutropenia on haloperidol, which was reversed when he was switched to quetiapine.

It is recommended that caution should be exercised when treating patients with antipsychotics and patients should be told to report high fevers and painful sore throats to their doctors as soon as possible.
