About quinagolide
Type de médicament | Dopamine receptor stimulant |
Utilisé pour | Hyperprolactinaemia (raised levels of prolactin in the blood) |
Aussi appelé | Norprolac® |
Disponible sous forme de | Comprimés |
Quinagolide helps reduce overproduction of a hormone called prolactin. Prolactin is the hormone which helps a woman to produce milk when she breastfeeds, but it is also involved in controlling the levels of other hormones within our bodies.
If you have hyperprolactinaemia, this means that the level of prolactin in your blood is higher than normal. Hyperprolactinémie can cause various symptoms, although these differ slightly between men and women. In men it can reduce sex drive (libido) and cause dysfonction érectile, and in women it can cause menstrual cycle and fertility problems. It may also cause milk to leak from the breasts (known as galactorrhoea). Quinagolide is prescribed to help prevent these symptoms.
Before taking quinagolide
Retour au sommaireSome medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking quinagolide it is important that your doctor or pharmacist knows:
If you are trying for a baby, or breastfeeding.
Si vous avez des problèmes avec le fonctionnement de votre foie, ou avec le fonctionnement de vos reins.
If you have ever had disturbed thinking (a psychotic disorder).
Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.
Si vous avez déjà eu une réaction allergique à un médicament.

How to take quinagolide
Retour au sommaireBefore you start taking the tablets, read the manufacturer's printed information leaflet from inside your pack and any additional information you are given by your doctor. The manufacturer's leaflet will give you more information about quinagolide and a full list of the side-effects which you may experience from taking it.
Take quinagolide exactly as your doctor tells you to. It is normal to be given a 'starter pack' of tablets to begin with. This will allow your dose to be increased slowly over a few days - side-effects are less likely if you start with a low dose and increase gradually. The 'starter pack' contains three pink (25 micrograms) tablets and three blue (50 micrograms) tablets. Take one pink tablet at bedtime on the first three evenings, and then take one blue tablet at bedtime for the following three evenings. After this, it is usual for the dose to be increased to one 75 micrograms tablet daily. These tablets are whitish in colour.
Take your doses in the evening after something to eat, such as a biscuit or a snack. You may find it helps to swallow the tablet with a drink of water.
If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, leave out the forgotten dose. Do not take two doses at the same time to make up for a missed dose.
Tirer le meilleur parti de votre traitement
Retour au sommaireDuring your treatment, your doctor will want you to have regular check-ups. Try to keep these regular appointments so that your progress can be monitored.
Some people may get low blood pressure during the first few days of starting treatment. This can make them feel dizzy or faint. If this happens to you, your blood pressure may need monitoring over the next few days. It is important that you do not drive and do not use tools or machines unless you feel well.
Successful treatment with quinagolide often restores fertility quite quickly. If you do not want to become pregnant, you will need to use contraception. Use a barrier method, such as a condom, because hormonal contraception ('the pill') is not suitable. Your doctor, nurse or family planning clinic can give you further advice.
Quinagolide should not usually be taken during pregnancy, so if you think you may have become pregnant while you are taking quinagolide, see your doctor as soon as possible to get the pregnancy confirmed.
Occasionally, people taking quinagolide have fallen asleep suddenly, with little or no warning of feeling tired beforehand. Until you know how you react, take extra care when you drive and if you operate machinery. If you do find yourself falling asleep suddenly, you should see your doctor as soon as possible. You should also avoid driving and avoid using tools and machines in the meantime.
If you drink alcohol, ask your doctor for advice about quinagolide and alcohol. Alcohol can increase the chance that you will experience side-effects and it may not be recommended.
Many people need to take quinagolide on a long-term basis, so you should continue to take the tablets regularly, unless you are told otherwise. Your doctor may want you to reduce your dose gradually before stopping. Stopping your treatment suddenly could lead to withdrawal symptoms such as tiredness, sweating, pain, anxiety and depression.

Questions fréquemment posées
What is hyperprolactinaemia and how does quinagolide help?
Hyperprolactinaemia means you have higher than normal levels of prolactin, a hormone which helps women produce milk and controls other hormones. In men, it can reduce sex drive and cause erectile dysfunction. In women, it can lead to menstrual cycle and fertility problems, and may also cause milk leakage from the breasts (galactorrhoea). Quinagolide is prescribed to help prevent these symptoms by reducing the overproduction of prolactin.
How quickly does quinagolide restore fertility?
Successful treatment with quinagolide often restores fertility quite quickly. If you do not wish to become pregnant, it is important to use contraception. Your doctor, nurse, or a family planning clinic can offer further advice on suitable methods, as barrier methods like condoms are recommended over hormonal contraception ('the pill') when taking quinagolide.
What should I do if I feel dizzy or faint after starting quinagolide?
It is possible to experience low blood pressure, which can cause dizziness or faintness, particularly during the first few days of treatment. If this happens, your blood pressure may need to be monitored. While you are feeling this way, you should not drive or operate tools or machines until you feel well and steady.
Can I drink alcohol while taking quinagolide?
You should ask your doctor for advice about drinking alcohol with quinagolide. Alcohol can increase your chances of experiencing side-effects, so it might not be recommended. It's best to discuss this with your doctor to understand the risks for you.
Are there any specific activities I should avoid while taking quinagolide due to unexpected sleepiness?
Occasionally, people taking quinagolide have fallen asleep suddenly without feeling tired beforehand. Until you know how you react to the medication, you should be extra careful when driving or operating machinery. If you do experience sudden sleepiness, you must see your doctor as soon as possible and avoid driving or using tools and machines in the meantime.
What specific withdrawal symptoms might I experience if I stop quinagolide suddenly?
If you stop quinagolide treatment suddenly, you could experience withdrawal symptoms. These may include tiredness, sweating, pain, anxiety, and depression. Your doctor may want to reduce your dose gradually before stopping to help prevent these effects.
Should I be concerned about any changes in my behaviour while taking quinagolide?
Yes, it is important to speak with your doctor if you notice any changes in your behaviour, especially if you develop strong urges or cravings that are unusual for you. This could include an increased desire to gamble, an increased sex drive (libido), compulsive shopping, or binge eating.
