Elevated prolactin levels are relatively rare in children but can be caused by certain medications or lesions of the pituitary gland (usually microadenomas). Hyperprolactinemia can cause galactorrhea (discharge of a milky substance from the nipples) and in girls can lead to menstrual irregularity. The first step in the evaluation is to determine why the elevation in prolactin level is occurring. Management depends on the underlying cause but can include medication.
