What is cabergoline, and what is it used for?
Cabergoline is a prescription medicine in the dopamine agonist class. It is used mainly to treat disorders caused by high prolactin levels (hyperprolactinemia), including certain prolactin-secreting pituitary tumors (prolactinomas) and related reproductive and hormone symptoms.
It’s also used in some clinical settings where lowering prolactin helps restore normal reproductive function and reduce tumor-related effects, under specialist care.
How does cabergoline work?
Cabergoline activates dopamine receptors, which lowers prolactin secretion from the pituitary gland. By reducing prolactin, it can shrink prolactinomas in some patients and improve symptoms tied to excess prolactin (such as irregular or absent periods and fertility issues).
What are common side effects people report?
Common side effects can include nausea, headache, dizziness, fatigue, and sometimes constipation or stomach upset. Symptoms related to lowered blood pressure (lightheadedness, especially when standing) can occur in some people.
If you’re taking it for hyperprolactinemia, side effects are often dose-related, so clinicians may adjust the dose to improve tolerability.
What risks do patients and prescribers watch for long-term?
Cabergoline has been associated in some patients—particularly with higher cumulative exposure—with heart valve problems. This is why clinicians may consider baseline and follow-up echocardiograms in patients who need longer-term treatment or higher doses, especially if risk factors are present.
The need and frequency of heart monitoring varies by dose and patient risk profile.
How is cabergoline typically taken?
Cabergoline dosing varies by the condition, starting dose, and how the patient responds. Many regimens are oral and can be taken once or more per week depending on the prescribed schedule.
Because it’s usually a long-term therapy, the dosing plan is often adjusted gradually to balance symptom control and side effects.
Is cabergoline available as a generic, and who makes it?
In many countries, cabergoline is available as a generic and under different brand names depending on region.

What should you ask your clinician?
Patients often get the most value from asking about:
- The goal of therapy (prolactin level targets and whether tumor shrinkage is expected)
- Your follow-up plan (how often prolactin and pituitary imaging are checked)
- Whether you need heart monitoring (and what schedule)
- How to manage side effects and whether dose changes are possible
- Whether you need to avoid certain medications or supplements that affect blood pressure or dopamine signaling
