Valproic Acid Induced Thrombocytopenia in an Elderly Man with Schizoaffective Disorder: A Case Report.

Abstract

This article reports an elderly male patient who has been diagnosed with chronic and refractory schizoaffective disorder. In an effort to manage his manic symptoms, he received a combination of clozapine, aripiprazole, and valproic acid as treatment. During the weekly complete blood count (CBC) test being done as part of his clozapine therapy, we incidentally discovered that he had developed asymptomatic thrombocytopenia, which we attributed to the valproic acid.
