- 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 breastfeed 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 high levels of prolactin caused by tumours of the pituitary
gland in both men and women.
- This medicine contains cabergoline and belongs to a class of medicines
called ‘dopamine agonists’.
Dopamine is produced naturally in the body and helps to transmit
messages to the brain.
- 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.
Do not take Dostinex

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 of pregnancy);
- If you are being treated with anti-psychotics or have a history of mental
illness associated with child-birth (puerperal psychosis);

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.
