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 brain.
- 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 started.
- 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

- If you have severe liver disease
- If you have high blood pressure in pregnancy associated with swelling and protein in the urine (toxaemia of pregnancy)
- If you are being treated with anti-psychotics or have a history of mental illness associated with child-birth (puerperal psychosis)
- 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 valvulopathy)
- 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)

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 Dostinexfor hormonal disorders should have regular gynaecological exams including smear tests. Your doctor will continue to monitor your medical condition while you are taking Dostinex.

- Medicines used to treat mental illness (e.g. anti-psychotic 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, these include:

- Antibiotics (e.g. erythromycin).

Pregnancy, breast-feeding and fertility Pregnancy
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.

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 1mg (two 0.5mg tablets) on the first day after delivery.
• To stop lactation once you have started to breast-feed: You should take 0.25mg (one half of Dostinex 0.5mg tablet) every 12 hours for two days.
• To reduce prolactin levels in other conditions: You should initially take one 0.5mg 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 4.5mg per week or until you have responded fully to treatment. The maximum dose should not exceed 3mg 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 , 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.
