A Case of Hyperprolactinemia with Galactorrhea Induced by Carbamazepine

Carbamazepine (CBZ) may alter the secretion of prolactin (PRL), however, there is no report about hyperprolactinemia with galactorrhea induced by CBZ medication. A 30-year-old woman presented with galactorrhea. She had been treated with CBZ for three years and hormonal study revealed increased serum PRL levels. Sella MRI showed no evidence of pituitary lesion. Two months after changing CBZ to oxcarbazepine, galatorrhea was improved and the serum PRL level was normalized.
