Aripiprazole, due to its partial agonist activity at the D2 receptors, is often recommended as the drug of choice in patients who develop antipsychotic-induced hyperprolactinemia. We report a case of a female patient who developed hyperprolactinemia while on treatment with aripiprazole. This partial D2 agonistic activity of aripiprazole could be dose related, and hence, at higher doses, aripiprazole by itself can have dopamine antagonistic properties and hence cause prolactin system abnormalities.
