How does Dostinex (Cabergoline) work?
Dostinex tablets contain the active ingredient cabergoline, which is a type of medicine called a dopamine agonist. Cabergoline works by mimicking the activity of a substance in the brain called dopamine. Cabergoline is mainly used to treat disorders that result from high levels of the hormone prolactin in the blood. Prolactin is produced by the pituitary gland in the brain. It is the hormone that stimulates the production of breast milk. Cabergoline decreases the production of prolactin from the pituitary gland by acting on dopamine receptors found on the pituitary gland. A high prolactin level is associated with several conditions. Over-production of this hormone can cause abnormal production of breast milk in both men and women (galactorrhoea). It can also cause womens’ menstrual periods to become irregular or stop altogether, and can stop ovulation, resulting in infertility. Reducing prolactin levels with cabergoline can therefore treat these conditions – stopping breast milk produc
