Package leaflet: Information for the patient

Read all of this leaflet carefully before you start
taking this medicine because it contains important
information for you.
- Keep this leaflet. You may need to read it again.
- If you have any further questions, ask your doctor
or pharmacist.
- This medicine has been prescribed for you only. Do
not pass it on to others. It may harm them, even if
their signs of illness are the same as yours.
- If you get any side effects, talk to your doctor or
pharmacist. This includes any possible side effects
not listed in this leaflet. See section 4.

1. What Dostinex is and what it is used for
- 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.

(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

your heart.

behaviours such as addictive gambling, excessive
eating or spending, an abnormally high sex drive or
an increase in sexual thoughts or feelings.
