1. WHAT DOSTINEX IS AND WHAT IT IS USED FOR
• Dostinex contains the active ingredient cabergoline. This medicine belongs to a class of medicines called
‘dopamine agonists’. Dopamine is produced naturally in the body and helps to transmit messages to the
• Dostinex is used to stop breast milk production (lactation) soon after childbirth, stillbirth, abortion or
miscarriage. It can also be used if you do not want to continue to breast-feed your baby once you have
• Dostinex can also be used to treat other conditions caused by hormonal disturbance which can result in
high levels of prolactin being produced. This includes lack of periods, infrequent and very light
menstruation, periods in which ovulation does not occur and secretion of milk from your breast without
breast-feeding. Also in conditions in which high levels of prolactin are due to unknown causes (idiopathic
hyperprolactinaemia) or are caused by tumours of the pituitary gland in both men and women.
• Cabergoline mimics the action of dopamine to reduce the production of prolactin in the blood. Prolactin is
the hormone which stimulates the breast to produce milk.
• Dostinex should only be used in adults. It is not suitable for children under the age of 16 years.
• You must talk to a doctor or pharmacist if you do not feel better or if you feel worse.
2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE DOSTINEX
Do not take Dostinex:
• If you are allergic to cabergoline, to other medicines called ergot alkaloids, (e.g. pergolide, bromocriptine,
lisuride, ergotamine or ergometrine) or to any of the other ingredients of this medicine (listed in section 6)
• If you have severe liver disease
• If you have high blood pressure in pregnancy associated with swelling and protein in the urine (toxaemia
• If you are being treated with anti-psychotics or have a history of mental illness associated with child-birth
• If you are pregnant or breast-feeding
• If you will be treated with Dostinex for a long period and have stiff and inflamed heart valves (cardiac
• If you have had fibrotic reactions (scar tissue) affecting your abdomen, heart or lungs.
Warnings and precautions
Talk to your doctor or pharmacist before taking Dostinex if you have or had any of the following conditions:
• Disease that involves the heart and blood vessels (cardiovascular disease)
• Cold hands and feet (Raynaud’s syndrome)
• Gnawing pain in the abdomen when hungry (peptic ulcer) or bleeding from the stomach and intestines
• History of serious mental disease, particularly psychotic disorders
• Reduced liver function
• Kidney function abnormality or kidney disease
• Increased blood pressure after giving birth
• Fibrotic reactions (scar tissue) affecting your heart, lungs or abdomen. In case you are treated with
Dostinex for a long period, your physician will check before starting treatment whether your heart, lungs
and kidneys are in good condition. They will also have an echocardiogram (an ultrasound test of the
heart) taken before treatment is started and at regular intervals during treatment. If fibrotic reactions
occur treatment will have to be discontinued
• Low blood pressure (postural hypotension) or you are taking any medicines to lower your blood pressure.
Tell your doctor if you or your family/carer notices that you are developing urges or cravings to behave in
ways that are unusual for you and you cannot resist the impulse, drive or temptation to carry out certain
activities that could harm yourself or others. These are called impulse control disorders and can include
behaviours such as addictive gambling, excessive eating or spending, an abnormally high sex drive or an
increase in sexual thoughts or feelings. Your doctor may need to adjust or stop your dose.
It is recommended that women on long term treatment with Dostinex for hormonal disorders should have
regular gynaecological exams including smear tests. Your doctor will continue to monitor your medical
condition while you are taking Dostinex tablets.
Other medicines and Dostinex
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines,
including medicines obtained without a prescription.
Some medicines can reduce the effectiveness of Dostinex, these include:
• Medicines used to treat mental illness (e.g. antipsychotic medicines like chlorpromazine, haloperidol)
• Medicines for nausea and vomiting (e.g. domperidone, metoclopramide).
Some medicines can increase the amount of Dostinex in your blood and so could increase the side effects,
• Medicines for Parkinson’s disease
• Medicines for severe migraine headaches (e.g. pergolide, bromocriptine, lisuride, ergotamine,
dihydroergotamine, ergometrine or methysergide)
• Antibiotics (e.g. erythromycin).
Dostinex with food and drink
See section 3 ‘How to take Dostinex’.
Pregnancy, breast-feeding and fertility
If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or
pharmacist for advice before taking this medicine. You should also take care not to become pregnant for at
least one month once you have stopped taking this medicine. If you become pregnant during treatment with
Dostinex, stop taking Dostinex and inform your doctor who will then monitor your pregnancy as Dostinex can
result in congenital abnormalities if you use it during pregnancy.
As Dostinex will stop you producing milk for your baby, you should not take this medicine if you plan to
breast-feed. If you need to take Dostinex you should use another method of feeding your baby.
Driving and using machines
Dostinex can cause drowsiness (somnolence) and sudden sleepy episodes, in some cases without any
warning signs or awareness. You are advised not to drive or operate machines or engage in activities
requiring mental alertness or coordination during treatment with this medicine. Your doctor will decide if you
can continue treatment on Dostinex if this occurs.
Dostinex contains lactose
Lactose is a type of sugar, if you have been told you have an intolerance to sugars, consult your doctor
before you take this medicine.
3. HOW TO TAKE DOSTINEX
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
It is recommended you take Dostinex with or after food to help reduce feelings of nausea or vomiting.
• To prevent milk production (lactation): You should take 1 mg (two 0.5 mg tablets) on the first day after
• To stop lactation once you have started to breast-feed: You should take 0.25 mg (one half of
Dostinex 0.5 mg tablet) every 12 hours for two days.
• To reduce prolactin levels in other conditions: You should initially take one 0.5 mg tablet (to be taken
in two doses) spread out over a week (e.g. half a tablet on Monday and the other half of the tablet on
Thursday). Your dose will be increased up to a maximum dose of 4.5 mg per week or until you have
responded fully to treatment. The maximum dose should not exceed 3 mg per day.
When you first start taking the tablet, it is recommended you slowly change position when trying to sit, stand
or lie down, this is because this medicine may cause a drop in blood pressure that could make you dizzy
when you move from a position. It is also recommended that you avoid alcohol and other medicines that
cause drowsiness as this could increase the risk of dizziness.
During treatment your doctor may need to check your blood pressure, particularly in the first few days of
treatment. A gynaecological assessment may also be carried out on the cells of your cervix or womb lining.
If you take more Dostinex than you should
If you take too many Dostinex tablets, contact your doctor immediately or go to the nearest hospital casualty
department. Symptoms of overdose may include nausea, vomiting, gastric complaints, low blood pressure
when standing, confusion/psychosis or hallucinations.
If you forget to take Dostinex
If you forget to take a dose take the next one as normal and tell your doctor if you have trouble remembering
to take your tablets. Do not take a double dose to make up for a forgotten dose.
If you stop taking Dostinex
Your doctor will advise you how long to take Dostinex. You should not stop until your doctor tells you.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
