Hyperprolactinemia is a common side effect of antipsychotic drugs. Although changes of antipsychotic drugs or reduction of their doses can solve this problem, a modification of the treatment regimen can lead to instability in patients. Herein, we followed up a patient with elevated prolactin caused by paliperidone and found that the prolactin level was decreased after the administration of a combination with a low-dose aripiprazole. In addition, we summarized and analyzed the findings from the case and the literature review conducted.
