Extremely Severe Hyperprolactinemia in a Woman With Renal Failure Receiving Risperidone

Abstract

We present the case of an epileptic patient who experienced risperidone-induced hyperprolactinemia with chronic renal failure under hemodialysis. Her prolactin level was 1058 ng/ml, which was unexpectedly high. Because prolactin is mainly excreted in the urine, clinicians should pay more attention to chronic renal failure as one of the risk factors of hyperprolactinemia when prescribing risperidone.
