Bromocriptin

About bromocriptine

Bromocriptine is prescribed for a number of different medical conditions. Your doctor will tell you why it has been prescribed for you.

Bromocriptine prevents the production of a chemical called prolactin. Prolactin is involved in a number of processes within the body, including milk production after childbirth. It also affects the levels of the hormones involved with controlling the menstrual cycle and fertility. Bromocriptine is therefore helpful in preventing or reducing milk production when this is needed for medical reasons. Likewise, it is helpful in some types of infertility, breast problems and menstrual problems caused by higher-than-usual levels of prolactin.

High levels of prolactin occur in people with prolactinomas. A prolactinoma is a non-cancerous swelling in the pituitary gland. This can cause various symptoms including reduced fertility, breast changes, and headaches. Prolactinomas can be treated successfully with medicines which reduce the production of prolactin, such as bromocriptine. In these cases, treatment is usually long-term.

Bromocriptine can be prescribed to treat Parkinson's disease, although other treatments are usually preferred. In Parkinson's disease, a number of cells in a small part of the brain become damaged and die. These brain cells normally pass messages down nerves in the spinal cord by producing a chemical called dopamine, and it is these messages which control the muscles of the body. As the cells are damaged, the amount of dopamine that is produced is reduced. A combination of the reduction of cells and a low level of dopamine in the cells in this part of the brain, causes nerve messages to the muscles to become slowed and abnormal. This produces the main symptoms of Parkinson's disease, which are stiffness, shaking (tremor), and slowness of movement. Bromocriptine encourages the release of dopamine which helps to ease these symptoms.

Bromocriptine also affects the production of growth hormone and has sometimes been used for the treatment of conditions such as acromegaly, although other treatments are often preferred. Acromegaly is a disorder which causes enlargement of the hands and feet, and makes facial features more prominent.

Before taking bromocriptine

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 bromocriptine it is important that your doctor knows:

• Wenn Sie schwanger sind oder stillen.

• If you have high blood pressure (hypertension), or if you have ever had high blood pressure during or soon after a pregnancy (pre-eclampsia).

• Wenn Sie ein Herzleiden oder eine Blutgefäßerkrankung haben.

• Wenn Sie jemals ein Magengeschwür gehabt haben.

• Wenn Sie ein Problem mit der Arbeitsweise Ihrer Leber haben.

• Wenn Sie ein Kreislaufproblem namens Raynaud-Syndrom haben.

• Wenn Sie schon einmal ein ernstes psychisches Problem hatten, wie z. B. eine psychotische Störung.

• Wenn Sie eine seltene vererbte Blutkrankheit namens Porphyrie haben.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take bromocriptine

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about bromocriptine and will provide you with a full list of the side-effects which you may experience from taking it.

• The dose you will need to take will depend upon the reason you are taking bromocriptine. Your doctor or pharmacist will tell you how much to take and when, and your dose will also be printed on the label of the pack to remind you. Read the directions from your doctor carefully and take bromocriptine exactly as you are told to. If you are taking bromocriptine for the first time, your doctor will give you a small dose and then gradually increase your dose over a few days. Slowly increasing your dose like this will help to reduce side-effects, such as dizziness, which can occur during the first few days of treatment.

• Try to take bromocriptine at the same time(s) each day. This will help you to remember to take it regularly. Swallow your dose with a drink of water at a mealtime.

• Wenn Sie die Einnahme einer Dosis vergessen haben, nehmen Sie sie ein, sobald Sie sich daran erinnern. Wenn Sie sich daran erinnern, dass es fast Zeit für die nächste Dosis ist, nehmen Sie die nächste Dosis, wenn sie fällig ist, aber lassen Sie die vergessene Dosis aus. Nehmen Sie nicht zwei Dosen zusammen ein, um eine vergessene Dosis auszugleichen.

Das Beste aus Ihrer Behandlung herausholen

• Try to keep your regular appointments with your doctor so your progress can be checked. Bromocriptine can occasionally cause lung problems, particularly in people who take it over a long period of time. In order for your doctor to check for this, you may need to have lung function tests, blood tests and an X-ray from time to time if you are taking bromocriptine long-term.

• If you are a woman (and taking bromocriptine for reasons other than trying for a baby) you may want to discuss suitable contraception with your doctor before taking bromocriptine. Hormonal forms of contraception (such as 'the pill') may not be suitable while you are taking bromocriptine.

• Sometimes people taking bromocriptine can fall asleep suddenly with little or no warning of being tired beforehand. Until you know how you react, take extra care if you drive or if you operate machinery. If you do find yourself falling asleep suddenly, you should see your doctor as soon as possible for advice; avoid driving and avoid using tools and machines in the meantime.

• Treatment with medicines like bromocriptine can sometimes cause problems with impulsive types of behaviour. If you notice any changes in your behaviour, such as an increased desire to gamble, binge eat, or spend excessively, or an increased sex drive, you must let your doctor know as soon as possible.

• If you drink alcohol, ask your doctor for advice. Your doctor may advise you not to drink alcohol while you are taking bromocriptine.

Can bromocriptine cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with bromocriptine. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to bromocriptine, speak with your doctor or pharmacist for further advice.
