Prolactin inhibitors are mainly used to treat hyperprolactinemia (high prolactin levels). [1] Agonists of the dopamine D 2 receptor such as bromocriptine and cabergoline are able to strongly suppress pituitary prolactin secretion and thereby decrease circulating prolactin levels, and so are most commonly used as prolactin inhibitors.

After delivery, progesterone concentrations decrease, and prolactin levels drop. Only during nipple stimulation will prolactin levels rise, allowing for milk production. [22] At 6 weeks post-birth (postpartum), estradiol concentrations decrease, and prolactin concentrations return to normal even during breastfeeding.
There are few treatments which increase prolactin levels in humans. Treatment differs based on the reason for diagnosis. Women who are diagnosed with hypoprolactinemia following lactation failure are typically advised to formula feed, although treatment with metoclopramide has been shown to increase milk supply in clinical studies.

Prolactin has a wide variety of effects. It stimulates the mammary glands to produce milk (): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands and prepare for milk production, which normally starts when levels of progesterone fall by the end of pregnancy and a suckling stimulus is present.
