hyperprolactinemia
"I have been diagnosed by micro prolactinoma (4x9 mm) about a month ago. My prolactin levels were around 150 ng/ml. I started using Cabergoline 0.25 mg twice a week. At the end of only one month, my prolactin levels dropped from 150 to 3 ng/ml. I have been told to use it for about 2 years to eventually shrink the tumor.
The side effects were (especially in the first 2 weeks) nausea, extreme fatigue, and depression. I started on Zoloft for the depression and it worked pretty well."
