Aripiprazole-induced pathological gambling: a report of 3 cases.

We report three cases of pathological gambling induced by aripiprazole, in patients with schizophrenia or schizoaffective disorder. All three patients had no history of pathological gambling, and they started gambling after initiation of treatment with Aripiprazole. The fact that pathological behaviour disappears quickly as medication was ended suggests that an elaborate behavioral manifestation could be related to dopaminergic tone in patients with schizophrenia. We recommend consideration with increased attention for the appearance of pathological gambling symptoms among patients on Aripiprazole.
