What is Cabergoline ?

Cabergoline is used to treat various forms of medical conditions caused by the development of too much of the hormone prolactin. It can be used to treat some menstrual issues, male and female fertility problems, and pituitary prolactinoma (tumors of the pituitary gland).

It functions by preventing the pituitary gland from producing and releasing the prolactin hormone from the brain. When prolactin levels are usual for 6 months, the use of cabergoline is normally stopped. When signs of too much prolactin arise again, it may be given again. This medication is available in tablet form for dosage.

Cabergoline Uses

This drug is used to treat the body with elevated levels of the hormone prolactin. Symptoms such as unwanted breast milk and missed periods can be caused by elevated levels of prolactin in women and can cause difficulties becoming pregnant. Symptoms such as enlarged breasts and diminished sexual ability/desire can be triggered by elevated levels of prolactin in men. Cabergoline is an ergot drug that functions by blocking the release of prolactin from the pituitary gland.

Cabergoline is also used to treat Parkinson's disease in some cases (a disorder of the nervous system that causes difficulties with movement, muscle control, and balance). Speak to your doctor about the complications of your condition using this drug.
