Aripiprazole-Induced Hypoprolactinemia in an Adult Male with First-Episode Psychosis.Clin Schizophr Relat Psychoses. 2016 Winter; 9(4):173-6.CS
Aripiprazole is an atypical antipsychotic that acts as a partial agonist at dopamine D2 receptors. Compared to other atypical antipsychotics, aripiprazole has less metabolic side effects and is less likely to increase prolactin. Moreover, it has been shown to have a unique prolactin lowering effect. While aripiprazole has been associated with subnormal prolactin levels in children, no documented cases of hypoprolactinemia in adults exist thus far. Here we report a case of aripiprazole-induced hypoprolactinemia in an adult male with first-episode psychosis, and the possible effects of abnormally low prolactin are discussed.
