Cabergoline is used to treat hyperprolactinemia (high levels of prolactin, a natural substance that helps breast-feeding women produce milk but can cause symptoms such as infertility, sexual problems, and bone loss in women who are not breast-feeding or men). Cabergoline is in a class of medications called dopamine receptor agonists. It works by decreasing the amount of prolactin in the body.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cardiac Valvulopathy and Pericardial Fibrosis : Before initiating cabergoline tablets, perform a cardiovascular evaluation, including echocardiogram, to evaluate for valvular disease. During cabergoline tablets treatment, monitor for the development of valvulopathy with a cardiac echocardiogram at intervals of 6 to 12 months or as clinically indicated and monitor for chest pain and signs and symptoms of heart failure (if heart failure occurs, exclude valvular fibrosis and pericarditis). Consider additional clinical and diagnostic monitoring at baseline and as necessary during cabergoline tablets treatment.
Use cabergoline tablets in patients treated with other drugs associated with valvulopathy only if the potential benefit of cabergoline tablets outweighs the risk. Discontinue cabergoline tablets if the patient has a new diagnosis of valvular regurgitation, valvular restriction, valve leaflet thickening, or pericarditis. ( 5.1 ) Pleural, Pulmonary and Retroperitoneal Fibrosis : During cabergoline tablets treatment monitor for signs and symptoms of progressive fibrosis, (e.g., pleuro-pulmonary disease, renal impairment, ureteral/abdominal vascular obstruction).
Consider clinical and diagnostic monitoring for pleural, pulmonary, and retroperitoneal fibrosis at baseline and as necessary during cabergoline tablets treatment. If pleural, pericardial, retroperitoneal, or pulmonary fibrosis occur, discontinue cabergoline tablets. ( 5.2 ) Orthostatic Hypotension : Check blood pressure at baseline and during treatment with cabergoline tablets and monitor for orthostatic hypotension.
( 5.3 ) Risks with Use of cabergoline tablets for Postpartum Lactation Inhibition or Suppression : Avoid use of cabergoline tablets for the inhibition or suppression of physiologic lactation. Use of bromocriptine, another dopamine agonist for this unapproved use has been associated with cases of hypertension, stroke, myocardial infarction, seizures, and death. ( 5.4 ) Impulse Control Disorders and Compulsive Behaviors : Specifically ask patients about the development of new or increased gambling urges, sexual urges, uncontrolled spending, or other urges while being treated with cabergoline tablets.
Consider dosage reduction or stopping cabergoline tablets if a patient develops such urges while taking cabergoline tablets. ( 5.5 )
5.1Cardiac Valvulopathy and Pericardial Fibrosis Before initiating cabergoline tablets, perform a cardiovascular evaluation, including with an echocardiogram, to evaluate for valvular disease. cabergoline tablets are contraindicated in the presence of valvular disease or pericardial fibrosis [see Contraindications ( 4 )]. Cases of valvular and pericardial fibrosis have often manifested as heart failure. Following cabergoline tablets treatment initiation, monitor for the development of valvulopathy with a cardiac echocardiogram at intervals of 6 to 12 months or as clinically indicated with new onset edema, cardiac murmur, dyspnea, or heart failure.
During cabergoline tablets treatment, monitor for chest pain and signs and symptoms of heart failure and if heart failure occurs, valvular fibrosis and pericarditis should be excluded. Consider clinical and diagnostic monitoring such as erythrocyte sedimentation rate, serum creatinine measurements, chest-x- ray, and other investigations and cardiac imaging at baseline and as necessary while patients are treated with during cabergoline tablets treatment. Use cabergoline tablets in patients treated with other drugs associated with valvulopathy only if the potential benefit of cabergoline tablets outweighs the risk.
Discontinue cabergoline tablets if the patient has a new diagnosis of valvular regurgitation, valvular restriction, valve leaflet thickening, or pericarditis. Postmarketing cases of cardiac valvulopathy have been reported in patients who received cabergoline tablets. These cases have generally occurred during administration of high doses of cabergoline…

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy : If conception occurs during cabergoline tablets therapy, discontinue cabergoline tablets if the risks to the mother or fetus outweigh the benefits to the mother ( 8.1 )
8.1Pregnancy Risk Summary If conception occurs during cabergoline tablets therapy, discontinue cabergoline tablets if the risks to the mother or fetus outweigh the benefits to the mother. There are risks to the mother associated with the use of cabergoline tablets ( see Clinical Considerations ). The estimated background risk of major birth defects and miscarriage in patients with hyperprolactinemic disorders, either idiopathic or due to pituitary adenomas is unknown.
All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Maternal Adverse Reactions: In general, avoid use of dopamine agonists, including cabergoline tablets, during pregnancy and the postpartum period.
The risks of cabergoline tablets use increase in pregnant females with pregnancy-induced hypertension, preeclampsia, and eclampsia. Data Human Data: Published case reports have not reported a clear association with cabergoline tablets and major birth defects, miscarriage, or adverse fetal outcomes when cabergoline tablets was used during early pregnancy. However, these case reports cannot definitely establish the absence of cabergoline tablets-associated risk.
Animal Data: Embryo-fetal development studies have been performed with cabergoline administered by oral gavage in mice, rats, and rabbits: There were no teratogenic effects in the presence of maternal toxicity in mice given cabergoline at doses up to 8 mg/kg/day (approximately 55 times the maximum recommended human dose based on body surface area) during the period of organogenesis. A dose of 0.012 mg/kg/day (approximately 0.14 times the maximum recommended human dose) administered during the period of organogenesis in rats caused an increase in post-implantation loss.
This finding is likely due to the role of prolactin in implantation in rats and is not thought to be relevant to humans. At doses of 0.5 mg/kg/day (approximately 19 times the maximum recommended human dose) administered during the period of organogenesis in rabbits, cabergoline caused maternal toxicity characterized by a loss of body weight and decreased food consumption. Doses of 4 mg/kg/day (approximately 150 times the maximum recommended human dose) administered during the period of organogenesis in the rabbit caused an increased occurrence of various malformations.
However, in another study in rabbits, no treatment-related malformations or embryofetal toxicity were observed at doses up to 8 mg/kg/day (approximately 300 times the maximum recommended human dose).
8.2Lactation Risk Summary Cabergoline tablets are not recommended in postpartum women who are breastfeeding or who are planning to breastfeed. Avoid use of cabergoline tablets for the inhibition or suppression of physiologic lactation [see Indications and Usage ( 1 ) and Warnings and Precautions ( 5 . 4 )] .
8.4Pediatric Use Safety and effectiveness of cabergoline tablets in pediatric patients have not been established.
8.5Geriatric Use Clinical studies of cabergoline tablets did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients.
8.6Hepatic Impairment The use of cabergoline tablets in patients with severe hepatic impairment (HI) (Child-Pugh C) is not recommended. When using cabergoline tablets in patients with moderate HI (Child-Pugh B) increase monitoring of cabergoline tablets-associated adverse reactions. The recommendations for use of cabergoline tablets in patients with mild HI (Child Pugh A) is the same as those with normal hepatic function. Patients w…

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Cabergoline is an ergot derivative and dopamine receptor agonist with a high affinity for D2 receptors. Results of in vitro studies demonstrate that cabergoline exerts a direct inhibitory effect on the secretion of prolactin by rat pituitary lactotrophs. Cabergoline decreased serum prolactin levels in reserpinized rats.
Receptor-binding studies indicate that cabergoline has low affinity for dopamine D1, α1- and α2-adrenergic, and 5-HT1- and 5- HT2-serotonin receptors.
12.2Pharmacodynamics The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of cabergoline tablets have not been fully characterized.
12.3Pharmacokinetics Absorption The time to reach maximum cabergoline plasma concentration was 2 to 3 hours after single oral doses of 0.5 mg to 1.5 mg (1.5 times the maximum recommended dose) of cabergoline tablets in healthy subjects. Following dosing of cabergoline tablets between 0.5 mg to 7 mg (7 times the maximum recommended dose), cabergoline plasma levels appeared to be dose-proportional. The absolute bioavailability of cabergoline is unknown.
A significant fraction of the administered dose undergoes a first-pass effect. Effect of Food: High-fat food did not alter the pharmacokinetics of cabergoline [see Dosage and Administration ( 2.2 )]. Distribution Protein binding of cabergoline was 40% to 42%.
Elimination The elimination half-life of cabergoline estimated from urinary data of 12 healthy subjects ranged between 63 to 69 hours. Metabolism: Cabergoline is extensively metabolized, predominately via hydrolysis of the acylurea bond or the urea moiety. Hydrolysis of the acylurea or urea moiety abolishes the prolactin-lowering effect of cabergoline, and major metabolites identified thus far do not contribute to the therapeutic effect.
Excretion: After oral dosing of radioactive cabergoline to 5 healthy volunteers, approximately 22% and 60% of the dose was excreted within 20 days in the urine and feces, respectively. Less than 4% of the dose was excreted unchanged in the urine. Nonrenal and renal clearances for cabergoline are about
3.2 L/min and
0.08L/min, respectively. Urinary excretion in hyperprolactinemic patients was similar. Specific Populations Patients with Hepatic Impairment: In a pharmacokinetic hepatic impairment (HI) study [see Use in Specific Populations ( 8.6 )] : In 4 cabergoline tablets-treated patients with mild HI (Child-Pugh A), no effect on mean area under the cabergoline plasma concentration-time curve (AUC) was observed.
In 4 cabergoline tablets-treated patients with moderate HI (Child-Pugh B) there was a 1.5-fold increase in mean cabergoline AUC. In 4 cabergoline tablets-treated patients with severe HI (Child-Pugh C) there was a 5.6-fold increase in the mean cabergoline AUC. Male and Female Patients: Males aged 20 to 34 years were shown to have had higher C max than females aged 20 to 27 years) while males aged 66 to 75 years had lower C max compared to females aged 66 to 74 years.
The clinical significance of the findings is unknown. Patients with Renal Impairment: The pharmacokinetics of cabergoline were not altered in 12 patients with moderate-to-severe renal impairment as assessed by creatinine clearance.
