Women who wish to avoid pregnancy should be advised to use mechanical contraception during treatment with cabergoline and after discontinuation of cabergoline until recurrence of anovulation. A single dose of 0.25 mg of cabergoline should not be exceeded in nursing women treated for suppression of established lactation to avoid potential postural hypotension (see section 4.2). In post-partum studies with cabergoline, blood pressure decreases were mostly asymptomatic and were frequently observed on a single occasion 2 to 4 days after treatment. Since decreases in blood pressure are frequently noted during the puerperium, independently of drug therapy, it is likely that many of the observed decreases in blood pressure after cabergoline administration were not drug-induced.

Pfizer Australia, part of the global pharmaceutical company Pfizer,offered a settlement to patients who developed an addition to gambling and sex after taking medication to treat Parkinson’s disease. Research has shown that around 17 per cent of people with Parkinson’s who take dopamine agonists experience impulsive and compulsive behaviour. A 74-year-old Parkinson’s patient became addicted to gambling in a bizarre side effect of his prescribed medication.

Delivery Options

There were maternotoxic effects but no teratogenic effects in mice given cabergoline at doses up to 8 mg/kg/day (approximately 55 times the maximum recommended human dose) during the period of organogenesis. All patients must undergo a cardiovascular evaluation, including echocardiogram to assess the potential presence of asymptomatic valvular disease. It is also appropriate to perform baseline investigations of erythrocyte sedimentation rate or other inflammatory markers, lung function/chest X-ray and renal function prior to initiation of therapy.

Clinical diagnostic monitoring for development of fibrotic disorders, as appropriate, is essential. Cabergoline is contraindicated in patients with hepatic insufficiency and with toxaemia of pregnancy. Cabergoline should not be co-administered with anti-psychotic medications or administered to women with a history of puerperal psychosis.


Skin discoloration was listed as an ‘infrequent’ adverse effect of the drug in its initial 1999 FDA approval notice, but cases were detailed in early clinical trials. Blocking its reuptake and allowing serotonin to remain in the synapse gives it more time to bind to other receptors in the brain, improving nerve cell-to-nerve cell communication which regulates mood. He later took out loans equalling more than $50,000 from four different banks and, in July 2006, sold his home, gambling away a total of $100,000. In March 2012, lawyers on behalf of a 66-year-old Australian man with Parkinson’s disease sued the pharmaceutical company Pfizer over claims that its drug Cabaser led him down a path of ruinous gambling that eventually led him to lose his home. Subsequent MRI scans of the volunteers’ brains showed that the more active dopamine was, the more money the volunteers expected to win. The exact mechanism behind Ambien that leads to parasomnias like sleep-walking and sleep-eating is not entirely understood, but it is believed to be a function of binding to central nervous system receptors and activating GABA to promote relaxation and sedation.

  • The man began gambling on video poker machines at first with his $850 per month retirement pension.
  • Research has shown that around 17 per cent of people with Parkinson’s who take dopamine agonists experience impulsive and compulsive behaviour.
  • ‘Pharmaceutical companies also have a responsibility to provide effective information, and work towards medication with less harmful side effects.
  • Ten days after administration about 18% and 72% of the radioactive dose was recovered in urine and faeces, respectively.

Erythrocyte sedimentation rate (ESR) has been found to be abnormally increased in association with pleural effusion/fibrosis. Chest x-ray examination is recommended in cases of unexplained ESR increases to abnormal values. As with other ergot derivatives, cabergoline should not be used in women with pregnancy-induced hypertension, for example, preeclampsia or post-partum hypertension, unless the potential benefit is judged to outweigh the possible risk. Before cabergoline administration, pregnancy should be excluded and after treatment pregnancy should be prevented for at least one month.

This Is A Prescription Product

While it’s not totally clear how many instances of priapism are linked to antipsychotics, some estimates say that the drugs are responsible forabout 50 percent of drug-related priapism. The receptors are located on smooth muscles – the kinds that produce involuntary actions. Activating them is believed to relax those smooth muscles which leads to a widening of blood vessels, allowing for increased blood flow to the penis. Common antibiotic medications including sulfonamides, chloramphenicol, penicillins, and quinolones have been known to cause Toxic epidermal necrolysis (TEN) that causes damage to 30 percent of the skin. While his side effect was caused by medication that is not used in the US, millions of Americans take drugs that can cause similarly bizarre symptoms. Ten days after administration about 18% and 72% of the radioactive dose was recovered in urine and faeces, respectively.

Dopamine agonist drugs have been shown to cause impulsive and compulsive behaviours in 17 per cent of those who use them. The Greek man’s desires to use slot machines started a month after his doctor prescribed pramipexole, a dopamine agonist. None of the men had prescriptions for the medication, suggesting they were not warned of the possible effect to their vision beforehand, and they started on the highest dose. The effect has been seen in men who take the highest recommended dose of the erection-causing medication whose main active ingredient is sildenafil.

Symptoms of overdose would likely be those of over-stimulation of dopamine receptors e.g. nausea, vomiting, gastric complaints, postural hypotension, confusion/psychosis or hallucinations. As with other ergot derivatives, cabergoline should not be used with macrolide antibiotics (e.g. erythromycin) due to increased systemic bioavailability of cabergoline. Some 170 patients claimed they were not warned of the side effects of the drug Cabaser between 1996 and 2010. For a small number of people, other types of Parkinson’s medications, in particular levodopa, have also been shown to have similar side effects. It is believed to be caused by inadvertently blocking an enzyme called phosphodiesterase 6 which overly sensitizes rod cells in the retina, which are most effective at picking up blue.

The pharmacokinetic and metabolic profiles of cabergoline have been studied in healthy volunteers of both sexes and in female hyperprolactinaemic patients. Due to the long half-life of the drug and limited data on in utero exposure, women planning to become pregnant should discontinue cabergoline one month before intended conception. If conception occurs during therapy, treatment should be discontinued as soon as pregnancy is confirmed to limit foetal exposure to the drug. The safety and efficacy of cabergoline have not yet been established in patients with renal and hepatic disease. Particular care should be taken when patients are taking concomitant psychoactive medication.
