Hyperprolactinemia with a normal TSH level requires an MRI to determine the presence of a tumor, microadenomas or macroadenomas, and other organic CNS lesions. Microadenomas and prolactinomas less than 1 cm in diameter are slow growing and are mostly found in the premenopausal population. Treatment should be considered to reverse hypoestrogenemic symptomatology, improve fertility, and/or eliminate bothersome galactorrhea.

Symptomatic hyperprolactinemia from a pituitary disorder should first be treated by dopamine agonists such as bromocriptine (Parlodel) and cabergoline (Dostinex). Pergolide has been associated with heart value abnormalities; it should not be used and was withdrawn from the US market in March, 2007.

Macroadenomas may also be treated with dopamine agonists initially. Occasionally, larger lesions fail to respond to medical therapy or present with acute vision changes. Referral with subsequent surgery or radiation is indicated. The recurrence rate after surgery can be as high as 50%. Patients with hyperprolactinemia associated with medications (eg, antipsychotics, metoclopramide) should consider discontinuation or switching of the causative medication if medically possible.

Some pituitary and hypothalamic tumors may require surgery and, in some cases, radiation therapy.
