What are the common side effects of Cabergoline?

Although cabergoline is considered well-tolerated in the clinical treatment of hyperprolactinemia (HPRL), due to its action on dopamine receptors, some patients may experience some adverse reactions during the medication. Common side effects are mainly related to its effects on the central nervous system, digestive system, and cardiovascular system. Some patients may experience mild nausea, vomiting or stomach discomfort when taking the drug for the first time. This is because the drug may stimulate the chemoreceptive areas of the gastrointestinal tract and central nervous system in the early stages. These symptoms can be reduced by taking it with a meal or at bedtime.

Central nervous system symptoms such as dizziness, fatigue, and drowsiness are also common adverse reactions. Especially at the beginning of treatment or during the dose adjustment stage, some patients may feel a drop in blood pressure or mild dizziness. Therefore, doctors usually recommend starting with a low dose and gradually increasing it to allow the body to adjust to the effects of the drug. In addition, a small number of people will experience changes in their mental status, such as mild anxiety, mood swings and even impulse control disorders, which are related to the activation of the dopamine system and need to be reported to the doctor in time.

In terms of cardiovascular aspects, cabergoline may occasionally cause orthostatic hypotension, especially when standing up or changing positions. Therefore, it is recommended to stand up slowly and avoid standing suddenly during medication. Very few patients with long-term high-dose use have reported heart valve fibrosis, which is related to the drug's 5-HT2B receptor agonistic effect. However, the risk is low at conventional therapeutic doses. However, long-term users still need to undergo regular cardiac ultrasound examinations to monitor heart valve function.

Overall, most of the adverse effects of cabergoline are mild to moderate, reversible, and will gradually lessen with prolonged treatment. Through reasonable dosage adjustment, regular review and communication with doctors, the risk of side effects can be effectively reduced and the safety and effectiveness of treatment can be ensured.
