Caberlin 0.5 Mg (Cabergoline)
Active ingredient: Cabergoline
Manufacturer : Sun Pharmaceuticals Industries
Product Code: PR10058
Cabergoline is an ergot-derived drug that is used to treat Prolactinoma, Cushing’s disease and other pituitary adenomas. It is a dopamine receptor agonist on D2 receptors. Due to its inhibitory effect on prolactin cells, it is successfully used to treat disorders of increased prolactin levels. Since its inception in 1981 it has replaced bromocriptine as the first-line drug in the treatment of Prolactinoma due to less severe side effects and higher affinity for dopamine D2 receptors.
Classification and mechanism of action
Prolactin is released by the anterior pituitary gland under the influence of dopamine. Cabergoline is a dopamine receptor agonist on D2 receptors, although it also has a lower affinity for dopamine D1, 5HT1 and 5HT2 serotonin, α1 and α2- adrenergic agonist. Cabergoline has also an inhibitory effect on pituitary lactotroph cells that release prolactin. In this way, they reduce the secretion of prolactin and help to shrink a Prolactinoma.

How to take Caberlin 0.5 Mg
Cabergoline should be taken by mouth with water twice a week, or as suggested by your doctor. It is advised to mark on your calendar when you have to take the medicine so you do not forget it and notice if the symptoms improved, persisted or got worse.
Cabergoline is given orally 0.25 mg twice a week as starting dose. If the prolactin levels are really high, or if despite the starting dose the symptoms did not improve, the dose can be increased to up to 1-2 mg twice a week. It is advised to check cardiac activity and do echocardiography before initiating the dose and continue that periodically once the treatment is going on for a long term. There are no food interactions; you can take it with or without food.
Contact your emergency if you develop symptoms like nasal congestion, fainting, hallucination and loss of consciousness.
If you miss a dose of Cabergoline take the missed pill right away, but if it is just about the time to take your next dose then take the scheduled dose instead and skip the missed dose. Do not take double doses. Inform your doctor for further suggestion.

How long should you take Caberlin 0.5 Mg?
Cabergoline should be taken for as long as your doctor has prescribed, increasing the dose if required after every 4 weeks. Once the prolactin levels have been maintained for 6 months the drug can be discontinued, with regular monitoring of prolactin levels to see if the treatment needs to be restarted.
