If you’ve recently been prescribed Cabergoline, you’re not alone. This medication is commonly used in the UK to treat conditions linked to high prolactin levels, such as prolactinomas (benign pituitary tumours), fertility issues, or irregular periods. It’s also sometimes used in the management of Parkinson’s disease or to help stop breast milk production after childbirth.
However, like any new treatment, starting Cabergoline can feel a little daunting. Here’s what to realistically expect during your first month, from dosage and side effects to monitoring and results.
Week 1: Starting slowly and gently
Dosage
Most people begin with a low dose, typically 0.25mg to 0.5mg per week, split into one or two doses. Your doctor will usually “start low and go slow” to reduce the risk of side effects.
For example, you might take 0.25mg on a Monday and another 0.25mg on Thursday.
This slower approach helps your body adjust and allows your GP or consultant to monitor how you respond.
Possible side effects
Early side effects can include:
- Light-headedness or dizziness (especially when standing)
- Nausea or slight stomach upset
- Feeling unusually sleepy or tired
- Mild headaches
These effects are usually temporary and tend to ease as your body adjusts.
Top tip: Take Cabergoline with food to minimise nausea, and drink plenty of water throughout the day.
Week 2: Keep an eye on how you feel
By now, many people find side effects are easing, or may not have had any at all. If you are still feeling a bit off, don’t panic. It’s common for your body to take a couple of weeks to adjust.
Stay in touch with your GP or specialist. You might be asked to report any side effects or changes in how you feel.
💬 Week 3: Starting to notice subtle changes
You may start to feel small but positive shifts, particularly if Cabergoline is being used to manage high prolactin symptoms. For example:
- Periods may become more regular
- You may notice a reduction in breast tenderness or discharge
- Mood may begin to feel more stable
- Libido could begin to improve
Keep in mind: hormonal changes don’t happen overnight. Patience is key.
Week 4: Review and monitoring
Around the 4-week mark, your doctor may:
- Review how you’re feeling
- Check in on any side effects
- Consider adjusting your dose slightly
- Book you in for a blood test to check prolactin levels
It’s important to attend all follow-up appointments, even if you’re feeling fine. Your dose may be adjusted depending on how your hormone levels respond.
What to look out for
While Cabergoline is generally well tolerated, it’s important to contact your GP if you experience:
- Severe nausea or vomiting
- Fainting spells
- Chest pain or shortness of breath
- Swelling in your hands or feet
These are rare side effects, but they do require medical attention.
Summary: First month highlights
| What to Expect | What to Do |
| Mild side effects | Take with food, stay hydrated |
| Hormonal changes begin | Be patient, your body needs time |
| Regular monitoring | Keep all appointments and report any changes |
| Dose adjustments possible | Based on how your prolactin levels respond |
Final thoughts
Starting Cabergoline doesn’t have to be overwhelming. Most people find it manageable with the right support and a bit of patience. By taking it exactly as prescribed and keeping in touch with your GP, you give yourself the best chance of success.
If you’re feeling unsure or have concerns about your medication, don’t hesitate to reach out to your healthcare provider. You’re not expected to figure it all out alone.
