Cabolac is a dopamine agonist. It is used for the treatment of a high level of prolactin. It is also helpful in stopping breast milk production in cases of stillbirth, abortion or miscarriage.
Cabolac should be taken with food, but take it at the same time to get the most benefit. It should be taken as your doctor's advice. The dose and how often you take it depends on what you are taking it for. Your doctor will decide how much you need to improve your symptoms. Swallow the tablets whole with a drink of water. You should take this medicine for as long as it is prescribed for you.
The most common side effects of this medicine include nausea, headache, dizziness, and low blood pressure. If these bother you or appear serious, let your doctor know. There may be ways of reducing or preventing them. To overcome dizziness, you must avoid driving or rise slowly from sitting or lying position.
Before taking this medicine, tell your doctor if you have ever had high blood pressure after birth, or had heart disease. Tell your doctor if you are pregnant, planning pregnancy or breastfeeding. Your doctor should also know about all other medicines you are taking as many of these may make this medicine less effective or change the way it works. Your doctor may check blood pressure regularly while taking this medicine.

How Cabolac works
Cabolac works by decreasing the release of prolactin, a hormone that stimulates breast milk production. This stops the production of breast milk in case of stillbirth, abortion or miscarriage.
What if you forget to take Cabolac?
If you miss a dose of Cabolac, skip it and continue with your normal schedule. Do not double the dose.

Suppression of lactation
Adult: 250 mcg every 12 hr for 2 days.
Hyperprolactinaemia-associated disorders
Adult: Initially, 500 mcg/wk then increased at mthly intervals by 500 mcg/wk according to response. Wkly dose may be admin on a single occasion or in 2 divided doses on separate days; doses >1 mg should be given as divided doses. Usual dose: 1 mg (up to 4.5 mg)/wk.
As monotherapy in Parkinson's disease; Adjunct to levodopa treatment in Parkinson's disease
Adult: Initially, 0.5 mg daily in monotherapy and 1 mg daily as adjunct, may increase in increments of 0.5-1 mg at 7- or 14-day intervals. Max: 3 mg daily.

Contraindication
Hypersensitivity to ergot derivatives. Uncontrolled hypertension.
Mode of Action
Cabergoline is a long-acting dopamine D2-agonist. It inhibits prolactin secretion through hypothalamic inhibitory control exerted through the release of dopamine.
Precaution
CV disease, Raynaud's syndrome, renal or hepatic impairment, peptic ulcer, GI bleeding, history of psychosis, hypertension. May affect ability to drive or operate machinery. Pregnancy, lactation. Prolonged use and/or usage of high doses may lead to psychiatric disorders, pleural/retroperitoneal fibrosis or cardiac valvular fibrosis. Monitor serum prolactin level mthly until normalisation. Monitor hepatic function regularly in patients with hepatic impairment.
Lactation: excretion in milk unknown; use with caution

Lactation: excretion in milk unknown; not recommended
Interaction
Increased risk of orthostatic hypotension when used with antihypertensives. May increase vasoconstriction effect of dopamine. May reduce vasodilation effect of nitroglycerin. Concurrent use with SSRIs or TCAs may increase the risk of serotonin syndrome.
Potentially Fatal: Risk of serotonin syndrome with sibutramine.
