Sometimes the natural balance of hormones inside your body can shift unexpectedly. Specifically, when a hormone called prolactin rises too high in your blood, it can cause various health challenges for both women and men. If your doctor has prescribed cabergoline to help lower and control your prolactin level, you might have several questions about what this medicine does.

What Is Cabergoline and What Does It Do?
Simply put, cabergoline is a prescription medicine that helps lower high levels of a hormone called prolactin in your blood. This specific hormone is naturally produced by your pituitary gland, which sits near the base of your brain. While prolactin levels are normally very high during pregnancy and when breastfeeding, having high levels at other times can disrupt your body's normal functions.
When your prolactin level remains abnormally high, it can lead to several noticeable changes and health concerns. Understanding why your doctor prescribed this medicine helps you see the bigger picture of your treatment plan.
High prolactin levels can lead to the following health concerns:
- In women, it can cause irregular menstrual periods, difficulty getting pregnant, unexpected breast milk production when not pregnant, and reduced sexual desire.
- In men, it can lead to erectile dysfunction, reduced sexual desire, and sometimes enlargement of breast tissue.
- In both women and men, long-term high prolactin can cause reduced bone density and strength over time.
The pituitary gland in your brain regulates important hormones like prolactin.
In addition to managing general hormone imbalances, doctors also use cabergoline to treat certain non-cancerous growths or tumors in the pituitary gland that release too much prolactin. In many international regions, this medicine is widely recognized and dispensed under the popular brand name Dostinex.
What to Tell Your Doctor Before Starting This Medicine
Giving your doctor a complete picture of your medical history is vital before you take your first dose. Certain health conditions can interact with cabergoline or require your doctor to adjust your treatment plan carefully.
Please inform your doctor right away if any of the following apply to you:
- You have a known heart disease or a history of heart valve problems.
- You suffer from high blood pressure or low blood pressure.
- You have any chronic liver disease or impaired liver function.
- You experience any lung disorders or breathing difficulties.
- You have ever had a severe allergic reaction to cabergoline, other ergot medicines, or any food dyes.
- You are currently pregnant, suspect you might be pregnant, or are trying to conceive.

How Should You Use This Medicine?
Using cabergoline correctly is straightforward, but following your specific prescription instructions precisely is very important for your safety and recovery.
- Swallow the tablet whole with a full glass of water.
- Take the medicine exactly as your doctor prescribed, on the correct days and at the scheduled times. Never take more than your prescribed amount.
- You can take this medicine either with food or on an empty stomach, depending on what feels most comfortable for your digestion.

What Happens If You Take Too Much? (Overdose)
Imagine a situation where you accidentally take more than your prescribed dose of cabergoline. If this happens, do not delay or wait to see how you feel. Contact your local poison control center right away, call emergency services such as 911 (US/Canada) or 999 (UK), or go straight to the nearest hospital emergency department (ER / A&E) right away.
What Happens If You Miss a Dose?
If you forget to take your dose on time, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose completely and continue with your normal schedule. Never take a double dose to make up for a forgotten pill.
Important Safety Precautions While Taking Cabergoline
Protecting your safety and well-being while taking this prescription requires paying attention to a few specific everyday precautions.

Some people taking this medicine experience unusual increases in sexual urges, urges to gamble, uncontrollable spending habits, or binge eating. If you notice any unusual changes in your behavior or desires, do not feel embarrassed. Talk to your doctor openly as soon as possible.
- Regular Medical Check-ups: Stay in close contact with your doctor to review your progress. You will need regular follow-up appointments and blood tests to monitor your prolactin levels.
