Side Effects Of Cabergoline
Cabergoline oral tablet can cause drowsiness as well as other side effects.
Nausea, vomiting, stomach upset, constipation, dizziness, lightheadedness, or tiredness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if any of these rare but serious side effects occur: persistent cough, mental/mood changes (such as nervousness), unusual strong urges (such as increased gambling, increased sexual urges), vision changes, painful menses, breast pain, symptoms of heart failure (such as shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).
Get medical help right away if you have any serious side effects, including: chest pain, signs of kidney problems (such as change in the amount of urine, lower back/flank pain).
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Side effects are mostly dose dependent. Much more severe side effects are reported for treatment of Parkinson’s disease and (off-label treatment) for restless leg syndrome which both typically require very high doses. The side effects are considered mild when used for treatment of hyperprolactinemia and other endocrine disorders or gynecologic indications where the typical dose is one hundredth to one tenth that for Parkinson’s disease.
Cabergoline requires slow dose titration (2–4 weeks for hyperprolactinemia, often much longer for other conditions) to minimise side effects. The extremely long bioavailability of the medication may complicate dosing regimens during titration and require particular precautions.
Cabergoline is considered the best tolerable option for hyperprolactinemia treatment although the newer and less tested quinagolide may offer similarly favourable side effect profile with quicker titration times.
Approximately 200 patients with newly diagnosed Parkinson’s disease participated in a clinical study of cabergoline monotherapy. Seventy-six (76) percent reported at least one side effect. These side effects were chiefly mild or moderate:
- GI tract: Side effects were extremely frequent. Fifty-three percent of patients reported side effects. Very frequent: Nausea (30%), constipation (22%), and dry mouth (10%). Frequent: Gastric irritation (7%), vomiting (5%), and dyspepsia (2%).
- Psychiatric disturbances and central nervous system (CNS): Altogether 51 percent of patients were affected. Very frequent: Sleep disturbances (somnolence 18%, insomnia 11%), vertigo (27%), and depression (13%). Frequent: dyskinesia (4%) and hallucinations (4%).
- Cardiovascular: Approximately 30 percent of patients experienced side effects. Most frequent were hypotension (10%), peripheral edema (14%) and non-specific edema (2%). Arrhythmias were encountered in 4.8%, palpitations in 4.3%, and angina pectoris in 1.4%.
In a combination study with 2,000 patients also treated with levodopa, the incidence and severity of side effects was comparable to monotherapy. Encountered side effects required a termination of cabergoline treatment in 15% of patients. Additional side effects were infrequent cases of hematological side effects, and an occasional increase in liver enzymes or serum creatinine without signs or symptoms.
As with other ergot derivatives, pleuritis, exudative pleura disease, pleura fibrosis, lung fibrosis, and pericarditis are seen. These side effects are noted in less than 2% of patients. They require immediate termination of treatment. Clinical improvement and normalization of X-ray findings are normally seen soon after cabergoline withdrawal. It appears that the dose typically used for treatment of hyperprolactinemia is too low to cause this type of side effects.
