Objectives: Aripiprazole is an antipsychotic that functions as a partial agonist in hypodopaminergic states and a dopamine antagonist in hyperdopaminergic states. Methods: This paper reports a series of five clinical cases of worsening psychotic symptoms in schizophrenic patients related to the initiation of aripiprazole, oral and injection, as combination therapy. Results: In all five cases, the switching of aripiprazole improved the psychotic symptoms. Conclusion Even with the suggestive relationship between aripiprazole therapy and the worsening of psychotic symptoms, further research is needed.
