How does bromocriptine treat hyperprolactinemia?
Bromocriptine is in a class of medications called dopamine receptor agonists. It treats hyperprolactinemia by decreasing the amount of prolactin in the body. It treats acromegaly by decreasing the amount of growth hormone in the body. It treats Parkinson’s disease by stimulating the nerves that control movement.

How does bromocriptine work for prolactinoma?
Dopamine agonists such as bromocriptine and cabergoline are the predominant treatment drugs for prolactinoma by inhibiting prolactin secretion and shrinking tumor size.
What are the effects of bromocriptine?
Nausea, vomiting, dizziness, drowsiness, lightheadedness, tiredness, constipation, or headache may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
What happens when prolactin hormone increases?
Excess prolactin can cause the production of breast milk in men and in women who are not pregnant or breastfeeding. In women, too much prolactin can also cause menstrual problems and infertility (the inability to get pregnant). In men, it can lead to lower sex drive and erectile dysfunction (ED).
How fast does bromocriptine lower prolactin?
Prolactin levels usually fall within the first two to three weeks of treatment, but detectable decreases in adenoma size take more time, usually several weeks to months. When the adenoma affects vision, improvement in vision may begin within days of starting treatment.
Why is dopamine agonist given in hyperprolactinemia?
Many dopamine agonists are used to control hyperprolactinaemia, resulting in reduced prolactin levels, restoration of gonadal function and reduction of tumour size in the vast majority of patients (Nunes 2011). All have a very high affinity for dopamine D2 receptors in the pituitary (Fitzgerald 2005).
What causes prolactin levels to increase?
Causes of Abnormal Prolactin Levels Prolactinoma (a benign tumor in your pituitary gland that produces too much prolactin) Diseases affecting the hypothalamus(the part of the brain that controls the pituitary gland) Anorexia(an eating disorder) Drugs that are used to treat depression, psychosis, and high blood pressure.
Does prolactin decrease dopamine?
It is well-known that dopamine constitutively inhibits prolactin (PRL) secretion via the dopamine receptor 2 (DR2D). If dopamine is increased or if dopamine receptors hyperfunction, PRL may be reduced.
What happens when prolactin is high?
How does bromocriptine make you feel?

Does bromocriptine increase prolactin?
How does prolactin affect serotonin?
It is some evidence that antidepressants that inhibit serotonin reuptake can increase the prolactin level. This adverse effect has been called serotonin overactivity. Selective serotonin-reuptake inhibitors (SSRIs) have been reported as the most common cause of drug-induced hyperprolactinemia.
