This was tested in people. That is the most reliable kind of research we share.
This looked at habits in people already on this medicine, so it is a warning sign to watch for, not a new treatment.
The short version
People taking cabergoline for a prolactinoma were more impulsive, and more of them shopped in ways they could not control.
What was studied. Researchers compared 131 people with a prolactinoma who were taking cabergoline to 131 healthy people. Everyone filled out questionnaires about impulsive habits, sex drive, gambling, shopping, and repeating pointless tasks.
What they found. The patients scored higher on impulsivity overall. More of them had trouble holding their attention, and that held up even after the researchers accounted for other differences between the groups. They were also much more likely to shop compulsively. The other habits, like gambling, were about the same in both groups. People with less schooling tended to be more impulsive and to shop compulsively.
What this means, and what it doesn't
What it could mean: If you take cabergoline, it may be worth telling your care team about changes in your spending, focus, or self-control. These habits can be missed unless someone asks. Bringing them up gives your doctor a chance to adjust your care.
What it doesn't mean: This does not mean cabergoline caused these habits. This was a study that compared two groups at one point in time. That kind of study can show a link, but it cannot prove one thing led to the other. It does not mean everyone on cabergoline will have these problems, and most people in the study did not. It is not a reason to stop your medicine on your own. Cabergoline is still the usual first treatment for a prolactinoma. This is not a new treatment, and it is not a cure for anything.
