What is the treatment for prolactinoma?
Prolactinomas can be treated with medication or surgery; medications used are drugs that act like dopamine (which inhibits prolactin secretion) such as bromocriptine or cabergoline. If there is no
response to medication, surgery can be done.
I’ve heard of macroprolactin, can you explain it?
Macroprolactin is an inactive form of prolactin; it is bound to proteins and is not a cause for concern. However, can cause elevated prolactin levels, so further evaluation is done in people with elevated prolactin to be sure it is not due to macroprolactin.
