How Galactorrhea Medications Work

Galactorrhea is a condition characterized by spontaneous milk production, often caused by an overproduction of prolactin. To treat this condition, medications that target the underlying cause are used.

Treatment with Dopamine Agonists (Gold Standard)

• Cabergoline is a dopamine agonist that works by stimulating dopamine receptors in the pituitary gland, which reduces prolactin secretion.

• Dopamine agonists are considered the gold standard for treating galactorrhea caused by prolactin-secreting tumors (prolactinomas) or hyperprolactinemia.

Alternative Treatments

• Selective estrogen receptor modulators (SERMs), such as Tamoxifen, can also be used to treat galactorrhea by blocking the action of estrogen on breast tissue.

• Aromatase inhibitors, like Anastrozole, reduce estrogen production in the body, which can help alleviate symptoms of galactorrhea.

• GnRH agonists, such as Leuprolide, work by initially stimulating and then downregulating GnRH receptors, leading to a decrease in prolactin secretion.
