With some kinds of small pituitary tumors, it is possible to use medication to stop the tumor from growing or to prevent its hormones from having effects on other parts of the body. Sometimes, it is possible to avoid surgery altogether and only be treated with medication. For example, medications are used to treat pituitary adenomas that secrete prolactin. The medicines commonly used are bromocriptine (Parlodel) and cabergoline (Dostinex). Although the medicine cannot destroy the tumor completely, they can control its hormone production and often can make it smaller. These and other medicines can also be used to help treat other types of pituitary tumors.
