Understanding Cabergoline: A Comprehensive Drug Description
Cabergoline is a medication primarily used for the treatment of hyperprolactinemia, a condition characterized by excessive levels of prolactin in the blood. This drug acts as a dopamine agonist, which means it mimics the action of dopamine in the brain, leading to decreased secretion of prolactin from the pituitary gland.
Mechanism of Action
The mechanism of action of cabergoline involves stimulation of dopamine D2 receptors, resulting in:
- Inhibition of prolactin secretion
- Reduction of tumor size in prolactin-secreting adenomas
- Improvement of symptoms associated with hyperprolactinemia
Indications
Cabergoline is indicated for various medical conditions, including:
- Hyperprolactinemic disorders
- Prolactinoma (a benign tumor of the pituitary gland)
- Management of Parkinson’s disease (as an adjunct therapy)
Dosage and Administration
The dosage of cabergoline varies based on the condition being treated:
- For hyperprolactinemia, the usual starting dose is 0.5 mg per week, which can be increased gradually.
- For Parkinson’s disease, doses may start at 1 mg per week, adjusted according to clinical response.
Side Effects
Common side effects associated with cabergoline include:
- Nausea
- Dizziness
- Headache
- Fatigue
- Low blood pressure
Serious side effects can occur but are less common, such as:
- Cardiac valve fibrosis
- Pulmonary hypertension
- Severe allergic reactions
Drug Interactions

FAQs
What should I do if I miss a dose of cabergoline?
If you miss a dose, take it as soon as you remember. If it’s close to your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose.
Can cabergoline be taken during pregnancy?
The safety of cabergoline during pregnancy has not been fully established. It should only be used if the potential benefits outweigh the risks. Consult your healthcare provider for guidance.
How long does it take for cabergoline to work?
Patients may begin to notice symptom improvement within a few days of starting treatment, but it can take weeks to achieve full therapeutic effects.
Conclusion
In summary, cabergoline is an effective medication for managing conditions related to high prolactin levels. Its ability to mimic dopamine action makes it a valuable option for treating prolactinomas and assisting in Parkinson’s disease management. Consultation with a healthcare professional is crucial for proper dosage, monitoring of side effects, and understanding potential interactions with other medications.
