Take quinagolide once a day. Take the tablet in the evening after something to eat.
Quinagolide may cause dizziness, particularly when you first start taking it. Let your doctor know if this becomes troublesome.
In rare cases, some 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.
|Type of medicine||Dopamine receptor stimulant|
|Used for||Hyperprolactinaemia (raised levels of prolactin in the blood)|
Quinagolide helps reduce overproduction of a hormone called prolactin. Prolactin is the hormone which helps a woman to produce milk when she breast-feeds, 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. Hyperprolactinaemia can cause various symptoms, although these differ slightly between men and women. In men it can reduce sex drive (libido) and cause erectile dysfunction, 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
Some 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 breast-feeding.
- If you have any problems with the way your liver works, or with the way your kidneys work.
- If you have ever had disturbed thinking (a psychotic disorder).
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
- If you have ever had an allergic reaction to a medicine.
How to take quinagolide
- Before 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.
Getting the most from your treatment
- During 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.
