Most people who take cabergoline do not experience significant side effects, although any bothersome symptoms that develop after beginning treatment with this medication should be reported to a doctor for further evaluation. Some of the most common cabergoline side effects include constipation, dizziness, and fatigue. More serious side effects may include abdominal pain, swelling, or painful menstrual periods. Potentially serious cabergoline side effects that should be reported to a doctor right away include mood changes, hallucinations, or allergic reactions. Questions or concerns about any of the potential cabergoline side effects should be directed to a doctor or pharmacist.
The majority of cabergoline side effects are relatively mild in nature and do not affect a person's ability to safely take this drug. Mild gastrointestinal disturbances such as nausea, constipation, and abdominal bloating are quite common. Excessive vomiting or severe abdominal pain, especially if accompanied by fever, should be reported to a doctor right away. Dizziness may occur when using this drug, although this symptom usually diminishes as the body adjusts to the medication. Caution should be used when driving a vehicle or performing tasks that require intense focus or concentration.
Women may experience increased pain during menstrual periods when taking cabergoline, and over-the-counter or prescription pain relievers may be needed to combat this symptom. Fatigue, dry mouth, and insomnia are sometimes reported by those using this drug. Skin blemishes, itching, or a pins and needles sensation are also possible cabergoline side effects. Increased libido, difficulty concentrating, and flu-like symptoms may sometimes result from the use of this medication.
Mental or emotional changes should be evaluated by a doctor right away. Depression, irritability, or aggressive behavior may be signs that the dosage needs to be changed or the medication discontinued. If a person who is taking this drug experiences hallucinations or delusions or exhibits aggressive behavior, emergency medical personnel should be contacted to help transport the patient to the nearest medical facility.
Allergic reactions are possible cabergoline side effects. Skin reactions may include itching, hives, or mild swelling. If the skin begins to blister or peel, a doctor should be notified. Anaphylaxis, a potentially life-threatening type of allergic reaction, may cause the throat or tongue to swell and often involves chest pain and difficulty breathing. Without immediate treatment, the throat could close up, preventing oxygen from reaching the brain and other vital organs of the body, leading to brain damage or even death.
