Prolactin is a hormone made by the pituitary gland. An abnormal result does not by itself explain the cause. This page withdraws previous medicine-selection and self-directed hormone-adjustment advice.
Evidence and limitations
NIDDK describes several possible causes of high prolactin, including medicines and certain health conditions. Assessment involves history, symptoms and relevant tests. Do not use an article to diagnose yourself from symptoms alone.
