About Dostinex
Overview
Dostinex contains cabergoline, a dopamine receptor agonist, and is available as prescription tablets. It treats disorders involving high prolactin levels in adults, either with no known cause or due to pituitary adenomas. It acts on dopamine receptors to reduce prolactin release. It should not be used to prevent or stop normal breast milk production after childbirth because of the risk of serious adverse reactions.
What it treats
- High prolactin levels (hyperprolactinemia) in adults, either with no known cause or caused by pituitary adenomas.
Safety information
Side effects
The most common side effects of cabergoline are nausea, headache and dizziness. Other reported effects include constipation, tiredness, weakness, stomach pain, indigestion, vomiting, a spinning sensation, sleepiness and dry mouth. Cabergoline can cause a drop in blood pressure when standing up. Tell your doctor if you feel dizzy or lightheaded when rising from sitting or lying down. This risk is greater if you also take medicines that lower blood pressure. Serious side effects include heart valve damage and scarring around the heart, in or around the lungs, or behind the abdominal organs. Contact your doctor promptly if you develop chest pain, shortness of breath, a persistent cough, swelling in your legs, pain in your side or lower back, or abdominal tenderness or a lump. Heart checks, including an echocardiogram, are needed before and during treatment. Contact your doctor if you develop new or stronger urges to gamble, spend money, eat excessively or engage in sexual activity, especially if these urges are difficult to control. Psychotic disorders and aggression have also been reported after approval; their frequency and relationship to cabergoline cannot be reliably established. Contact your doctor if these occur.
When to call your doctor
If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.
Before taking this medicine
Do not take cabergoline if you have uncontrolled high blood pressure, a known allergy to ergot derivatives, a history of heart valve disease, or a history of fibrosis (scarring) around the heart, in the lungs or their lining, or in the tissues behind the abdominal cavity. Before treatment, your clinician should assess your heart, including an echocardiogram to check the valves. Repeat heart scans and monitoring are needed during treatment. Report chest pain, shortness of breath, persistent cough, leg swelling, flank pain or abdominal tenderness, as these may indicate heart problems or fibrosis. Treatment must be stopped if certain new valve abnormalities, inflammation around the heart or fibrosis develop. Cabergoline can cause a drop in blood pressure when standing, particularly if you also take medicines that lower blood pressure. Blood pressure should be checked before and during treatment. Take care when getting up from sitting or lying down, and report dizziness or lightheadedness. Other medicines associated with heart valve problems require a careful assessment of benefits and risks. Tell your clinician about new or increased urges to gamble, spend money, eat compulsively or engage in sexual activity, especially if these urges are difficult to control. Treatment may need to be changed or stopped. Cabergoline should not be used to prevent or stop normal milk production after childbirth because of the risk of serious adverse reactions. If pregnancy occurs during treatment, your clinician should reassess the benefits and risks and stop treatment if the risks to you or the fetus outweigh the benefits to you.
Interactions
Cabergoline is not recommended for use with medicines that block dopamine D2 receptors, including phenothiazines, butyrophenones, thioxanthenes and metoclopramide. Tell your doctor if you take any of these medicines.
