Dopamine agonists such as bromocriptine (Parlodel and Cycloset) are the most common treatment for high levels of prolactin. These medications help the brain produce dopamine to control high prolactin levels. They can also shrink prolactinoma tumors.

Does high prolactin need to be treated?

Dopamine agonists can decrease the production of prolactin and shrink the size of the tumor. Drugs can eliminate symptoms for most people with prolactinomas.
