Why it's used
Cabergoline is used to treat high levels of prolactin in your body. This happens when your pituitary gland makes extra prolactin. High prolactin levels may be caused by a hormone problem or by a tumor in your pituitary gland.
High prolactin levels can cause changes in a woman’s ovulation, menstrual cycle, and breast milk production. In men, high prolactin levels can affect reproduction and cause sexual issues. These include a decreased sex drive and not being able to get or keep an erection.
How it works
Cabergoline belongs to a class of drugs called dopamine agonists. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
