Patient on off-label cabergoline develops impulse control disorder as tumor grows
An study in Cureus.com examines the case of a 19-year-old man with a prolactinoma who was given off-label cabergoline at three times the normal dose for ten years. He developed an impulse control disorder and a spending and gambling problem, and was lost to follow-up. Radiosurgery was rejected, as the patient was deemed unable to comply with the necessary follow-up regime. It was later discovered that his tumor was resistant to cabergoline and had grown and extended into the cavernous sinus, making it inoperable.
