... different person. He is depressed, anxious, cannot sleep and obsesses about minor issues. He is also quick to anger. He takes 0.5 mg.-1 1/2 pills twice a week. He had this Prolactinoma on his Pituitary gland for 10 years before we were told by a new doctor who studied all his scans. Radiology in 2 hospitals doing pre-op sinus series missed it - it was 15 mm. The tumor is gone becasue of the Cabergoline but the endocronologist wants him on it for life to prevent the tumor's return. Does anyone out there have any of these symptoms?
