Fluoxetine augmentation of clozapine treatment in patients with schizophrenia.

Abstract

The authors examined the efficacy of fluoxetine augmentation of clozapine treatment response in schizophrenic outpatients who, despite adequate treatment with clozapine, continued to exhibit persistent positive or negative symptoms. Thirty-three patients completed on 8-week, double-blind, parallel-groups comparison of adjunctive fluoxetine and placebo. There were no significant differences in positive, negative, depressive, or obsessive-compulsive symptoms between patients given adjunctive fluoxetine or placebo. These results suggest that fluoxetine is not effective in augmenting clozapine treatment response.
