Olanzapine augmentation of clozapine

Ann Clin Psychiatry. 1998 Sep;10(3):113-5. doi: 10.1023/a:1022350221192.

Abstract

In clinical practice, patients are encountered who are partial responders or nonresponders to clozapine. There are others who are unable to tolerate a high dosage of clozapine. In the two cases presented, we propose an alternative strategy using olanzapine in combination with clozapine in treatment-refractory patients. Olanzapine was found to be helpful in these patients, however, controlled studies are needed.
