The patient’s laboratory reports showed a gradual decline of leukocytes and neutrophils after resolution and rechallenging. This was reversed with the discontinuation of risperidone and by switching to olanzapine. In this case report, we also discuss the updated evidence base for management of risperidone-induced neutropenia. Keywords: risperidone, antipsychotics, neutropenia, blood dyscrasias
