Why would prolactin levels be elevated?
There are several causes for high prolactin levels (called hyperprolactinemia), including: • Prolactin producing tumors in the pituitary gland – these are called prolactinomas • Use of certain medications including tranquilizers such as Haldol, some antidepressants, Reglan (used for reflux) and some drugs used to treat hypertension • Hypothyroidism • Pituitary tumors other than prolactinomas or tumors in the area around the pituitary • Stimulation of the breast, or orgasm shortly before the blood is drawn for the test Symptoms and problems caused by high prolactin levels in women • High prolactin will decrease FSH (follicle stimulating hormone) levels. This leads to irregular ovulation and irregular menstrual periods, or no periods at all – amenorrhea.
