Dostinex

Dostinex is a medication that contains the ingredient cabergoline. This is a dopamine-agonist drug that helps with some fertility issues, as well as stopping the production of breast milk.


Dostinex stops the production of prolactin, a hormone that in excessive levels, can cause issues with fertility, and affect other hormones such as oestrogen, progesterone and FSH, which can mean that a woman stops ovulating, hindering conception. Lowering the levels of this hormone in your body encourages regular ovulation and can increase your chances of becoming pregnant.

What is Dostinex?

Dostinex is a dopamine-agonist medication that’s prescribed to stop the production of breast milk, and also to help with some fertility issues. It contains the ingredient cabergoline, which inhibits the production of prolactin, a hormone secreted by the pituitary gland.

How does Dostinex work?

Dostinex works by reducing prolactin levels in the body. It does this by stopping the pituitary gland from making the hormone, restoring the hormones to a regular balance that should be present in the body. Prolactin can impact other hormones such as oestrogen, progesterone, and follicle stimulating hormone (FSH), all of which contribute to a woman’s ability to conceive a child. Excess levels of prolactin can cause a woman to stop ovulating, therefore causing fertility issues. Dostinex aims to rectify this and encourage ovulation once again.

Your prolactin levels might be high for several reasons, including:

  • Benign tumour on the pituitary gland
  • Non-secreting tumours on the pituitary gland
  • Polycystic Ovary Syndrome (PCOS)
  • Hypothyroidism
  • Head injury

Despite the cause of your prolactin levels, Dostinex should be able to regulate your hormones and encourage ovulation.

Can I take Dostinex?

Due to the way Dostinex works, and some of the side effects it might cause, there are some people that should avoid using the medication, or book an appointment with their GP to talk through the risks and benefits of using Dostinex. If you have any of the following conditions or complaints, you should speak to your own doctor:

  • Allergic to any ingredients of Dostinex
  • Allergic to similar medicines, including pergolide, bromocriptine, ergotamine, and ergometrine
  • Severe liver disease
  • Toxaemia of pregnancy
  • Treated with anti-psychotics
  • History of mental illness associated with childbirth
  • Pregnant
  • Breast feeding
  • Cardial valvulopathy
  • Scar tissue affecting abdomen, heart or lungs
  • Cardiovascular disease
  • Raynaud’s syndrome
  • Stomach ulcer
  • Gastrointestinal bleeding
  • History of serious mental illness
  • Reduced liver function
  • Kidney function abnormality
  • Kidney disease
  • Increased blood pressure after giving birth
  • Low blood pressure

You should be monitored regularly if you’ll be using Dostinex for a long time. As part of this monitoring, you may be referred for gynaecological examinations and smear tests.

Does Dostinex interact with any other medicines?

There are some medications that aren’t advised to be taken with Dostinex. It might cause one of the medications to not be as effective, or increase the risk or severity of side effects. It doesn’t always mean that you aren’t able to take Dostinex, but you may need a reduced dose or close monitoring. Some of the medicines listed as potential interactions include:

  • Antibiotics
  • Bromocriptine
  • Chlorpromazine
  • Dihydroergotamine
  • Domperidone
  • Ergometrine
  • Ergotamine
  • Erythromycin
  • Haloperidol
  • Lisuride
  • Medicines for mental illness
  • Medicines for nausea and vomiting
  • Medicines for Parkinson’s disease
  • Medicines for severe migraine headaches
  • Methysergide
  • Metoclopramide
  • Pergolide

We’ve listed both the names medicines in the patient information leaflet as well as some families of medications mentioned. If you aren’t sure if you’re taking any of the above, list all of your current medications down and take it to your local pharmacist to review. They should be able to tell you whether Dostinex is suitable for you or whether you should make an appointment with your GP.

What are the side effects of Dostinex?

Dostinex affects the hormonal balance in your body, so it’s unsurprising that it can cause some side effects. However, some women don’t feel these at all, whilst others only experience them to a mild degree. In rare cases, some women have to stop taking the medication due to the side effects, but this is something that you’ll need to decide with your GP when you know how Dostinex affects you. Some of the most common side effects of Dostinex are:

  • Drowsiness
  • Nausea
  • Headache
  • Dizziness
  • Vertigo
  • Stomach pain
  • Indigestion
  • Inflamed stomach lining
  • Fatigue
  • Weakness
  • Constipation
  • Blurred vision
  • Low blood pressure post-childbirth
  • Breast pain
  • Depression
  • Sleep disturbances
  • Excessive daytime fatigue
  • Vomiting
  • Low blood pressure
  • Hot flushes

In addition to these, there are also some other side effects that are important to know about as they require urgent treatment. These include:

  • Pericarditis
  • Pericardial effusion
  • Allergic reaction

These are all conditions which need emergency treatment, and the symptoms to look out for in pericarditis and pericardial effusion are:

  • Difficulty breathing
  • Shortness of breath
  • Pounding heart
  • Feeling faint
  • Chest pain
  • Back pain
  • Pelvic pain
  • Swollen legs

If you think you may be experiencing this, or anaphylaxis, call 999 and describe your symptoms, telling them what you’ve taken.

For the most part, other side effects are generally manageable, but if you find yourself struggling, you should make an appointment with your doctor to see whether alternative treatments are available or whether you can do anything to ease the symptoms caused by the medication.

Can I drive whilst taking Dostinex?

As Dostinex can cause drowsiness and dizziness, it’s best to wait until you know how the medicine affects you. If you feel unwell, tired, or dizzy, please refrain from driving until you feel better. If you need to go anywhere, you should use public transport or ask a friend or relative to take you.

If you’re unaffected by the drug and feel safe enough to drive, it should be safe to do so.
