Abstract

The combination of clozapine and other potentially leukopenic drugs may pose a greater risk for neutropenia. However, neutropenia may not always be due to clozapine. When adding potentially leukopenic drugs, clinicians should look for possible alternatives especially as clozapine is often a drug used as the last resort in treatment refractory schizophrenia.
