Additional information
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Drug interactions
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, check with your doctor or pharmacist before taking any new medicines while taking this one, to ensure that the combination is safe.
This medicine is not recommended for use in combination with other ergot alkaloid derivatives, such as pergolide, bromocriptine, lisuride, ergotamine, dihydroergotamine, methysergide or ergometrine.
There may be an increased risk of a drop in blood pressure that makes you feel dizzy if this medicine is taken in combination with other medicines that can lower blood pressure, for example medicines to treat high blood pressure (antihypertensives). Tell your doctor if you feel dizzy after starting treatment with this medicine, as your doctor may need to adjust the dose of your blood pressure medicine.
This medicine should not normally be taken in combination with the following medicines, as these work by decreasing the activity of dopamine in the brain and so may oppose the effect of cabergoline:
• antipsychotic medicines, eg chlorpromazine, haloperidol
• domperidone
• metoclopramide.
Macrolide-type antibiotics such as erythromycin may possibly increase the concentration of cabergoline in the blood, which may increase the risk of its side effects. However, small amounts of erythromycin applied to the skin can be used safely.
