Cabergoline is a medication primarily used to treat hyperprolactinemia, a condition characterized by elevated levels of the hormone prolactin in the blood. It works by mimicking the action of dopamine, a neurotransmitter in the brain that inhibits the secretion of prolactin from the pituitary gland. By binding to dopamine receptors, cabergoline effectively reduces prolactin levels, which can alleviate symptoms such as irregular menstrual periods, infertility, and galactorrhea (unintended lactation).

Additionally, cabergoline is sometimes prescribed off-label for other conditions such as Parkinson’s disease, restless legs syndrome, and certain types of acromegaly. It is typically taken orally in the form of tablets. Like any medication, cabergoline may cause side effects, including nausea, dizziness, headache, and fatigue, although these are often mild and transient. However, it can also lead to more serious adverse effects such as hypotension, cardiac valve disorders, and psychiatric symptoms, particularly with long-term use or at higher doses.

Therefore, it is essential to use cabergoline under the supervision of a qualified healthcare provider who can monitor its effects and adjust the dosage as needed.
