It also has been suggested that it has a possible recreational use in reducing or eliminating the male refractory period, thereby  allowing men to experience multiple ejaculatory orgasms in rapid succession, and at least two scientific studies support those speculations. : e28–e33  Additionally, a systematic review and meta-analysis concluded that prophylactic treatment with cabergoline reduces the incidence, but not the severity, of ovarian hyperstimulation syndrome (OHSS), without compromising pregnancy outcomes, in females undergoing stimulated cycles of in vitro fertilization (IVF). Also, a study on rats found that cabergoline reduces voluntary alcohol consumption, possibly by increasing GDNF expression in the ventral tegmental area. It may be used in the treatment of restless legs syndrome. Pregnancy and lactation
Relatively little is known about the effects of this medication during pregnancy and lactation. In some cases the related bromocriptine may be an alternative when pregnancy is expected. Pregnancy: available preliminary data indicates a somewhat increased rate of congenital abnormalities in patients who became pregnant while treated with cabergoline.. However, one study concluded that "foetal exposure to cabergoline through early pregnancy does not induce any increase in the risk of miscarriage or foetal malformation." Lactation: In rats cabergoline was found in the maternal milk. Since it is not known if this effect also occurs in humans, breastfeeding is usually not recommended if/when treatment with cabergoline is necessary. Lactation suppression: In some countries cabergoline (Dostinex) is sometimes used as a lactation suppressant. It is also used in veterinary medicine to treat false pregnancy in dogs.
Cabergoline, sold under the brand name Dostinex among others, is a dopaminergic medication used in the treatment of high prolactin levels, prolactinomas, Parkinsons disease, and for other indications. It is taken by mouth. Cabergoline is an ergot derivative and a potent dopamine D2 receptor agonist.Cabergoline was patented in 1980 and approved for medical use in 1993. Medical uses
Lactation suppression
Hyperprolactinemia
Adjunctive therapy of prolactin-producing pituitary gland tumors (prolactinomas);
Monotherapy of Parkinsons disease in the early phase;
Combination therapy, together with levodopa and a decarboxylase inhibitor such as carbidopa, in progressive-phase Parkinsons disease;
In some countries also: ablactation and dysfunctions associated with hyperprolactinemia (amenorrhea, oligomenorrhea, anovulation, nonpuerperal mastitis and galactorrhea);
Treatment of uterine fibroids. Adjunctive therapy of acromegaly, cabergoline has low efficacy in suppressing growth hormone levels and is highly efficient in suppressing hyperprolactinemia that is present in 20-30% of acromegaly cases; growth hormone and prolactin are similar structurally and have similar effects in many target tissues, therefore targeting prolactin may help symptoms when growth hormone secretion can not be sufficiently controlled by other methods;Cabergoline is frequently used as a first-line agent in the management of prolactinomas due to its higher affinity for D2 receptor sites, less severe side effects, and more convenient dosing schedule than the older bromocriptine, though in pregnancy bromocriptine is often still chosen since there is less data on safety in pregnancy for cabergoline. Off-label
It has at times been used as an adjunct to SSRI antidepressants as there is some evidence that it counteracts certain side effects of those drugs, such as reduced libido and anorgasmia.
