Medication
There's not really a cure that can get rid of prolactinoma, but there are treatments that can successfully reduce or eliminate symptoms. Most cases of prolactinoma are treated with medications (most commonly drugs called dopamine agonists) that regulate prolactin levels and help shrink tumors.
Procedures
Prolactin causes the breasts to grow and make milk during pregnancy and after birth. Prolactin levels are normally high for pregnant women and new mothers. Levels are normally low for nonpregnant women and for men. If prolactin levels are higher than normal, it often means there is a type of tumor of the pituitary gland, known as a prolactinoma. This tumor makes the gland produce too much prolactin.
Therapy
The goals for treatment of a prolactinoma are to:
- return prolactin secretion to normal,
- reduce tumor size,
- correct any vision abnormalities, and
- restore the normal function of the pituitary gland.

What are the medical treatment options for prolactinoma?
Oral medications known as dopamine agonists are generally used to treat a prolactinoma. These drugs mimic the effects of dopamine — the brain chemical that controls how much prolactin is made. Dopamine agonists can decrease the production of prolactin and shrink the size of the tumor.
Can prolactinoma be cured?
A prolactinoma won't go away on its own without treatment. Long-term medication can shrink the tumor until it's gone. However, it's important to note that prolactinomas can come back, even after successful treatment with medication or surgery.
How long is treatment for prolactinoma?
Prolactin levels usually fall within the first two to three weeks of treatment, but detectable decreases in adenoma size take more time, usually several weeks to months.
What is the best treatment for prolactin?
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. Your doctor may recommend that you take cabergoline.

Untreated, a prolactinoma can cause: Reduced hormone production if the tumor presses on the pituitary gland, which may lead to symptoms such as weight loss or fatigue. Osteoporosis (brittle, fragile bones) Pregnancy complications.
When is surgery needed for prolactinoma?
Surgery. In some cases, when a prolactinoma is large, a woman may choose to have surgery to remove the tumor before trying to become pregnant. Transsphenoidal surgery is most commonly used to treat prolactinoma. The surgery is done through an incision, or cut, at the back of the nasal cavity or under the upper lip.

How serious is high prolactin?
Excess prolactin can cause the production of breast milk in men and in women who are not pregnant or breastfeeding. In women, too much prolactin can also cause menstrual problems and infertility (the inability to get pregnant). In men, it can lead to lower sex drive and erectile dysfunction (ED).
Does high prolactin always mean tumor?
High levels of prolactin found in tests repeated several times on different days associated with a shrinkage in the size of the tumor usually confirm the diagnosis. However, prolactin levels usually correlate with tumor size, hence microadenomas may be associated with moderate levels of prolactin.
Does a prolactinoma cause weight gain?
Conclusion: Weight gain and elevated body weight are frequently associated with prolactinomas regardless of a mass effect on the hypothalamus or pituitary function. In this series, weight loss was recorded in 70% of prolactinomas patients and in 90% of male patients who normalized their prolactin levels.
What level of prolactin indicates a tumor?
Prolactin levels are usually directly proportionate to the size of tumor ranging from below 200 ng/ml with less than 1 cm, 200 ng/ml to 1000 ng/ml with 1 cm to 2 cm and more than 1000 ng/ml with tumor sized more than 2 cm in diameter.
What is the goal of prolactin therapy?
The goal of treatment is to return prolactin secretion to normal , reduce tumor size, correct any visual abnormalities and restore normal pituitary function. In the case of very large tumors, only partial achievement of this goal may be possible. Because dopamine is the chemical that normally inhibits prolactin secretion, doctors first treat a prolactinoma with dopamine agents (agonists).
Is surgical treatment better than long term treatment for prolactinomas?
While medical treatment is often the first option for prolactinomas, in selected cases, surgical treatment might be a better choice than long-term medication because surgery is curative in a high percentage of cases. Diagnosis. Next Section.
What tests are needed for prolactinoma?
If a prolactinoma is found, you may need more blood tests to see if your pituitary gland is making other hormones like it should. You may also need more MRIs to see if the tumor grows and if it responds to treatment. Certain drugs can shrink it, especially when it's small.
What happens when a prolactinoma is large?
When a prolactinoma becomes large, it may press up against other nearby tissues. Symptoms then can include vision loss, vision changes, and headaches. When a man is diagnosed with a prolactinoma, it tends to be large. Men often aren't diagnosed when they have early signs, which include:
Why are prolactinomas more likely to be found in women?
Because changes in a woman's period are obvious , prolactinomas are more likely to be found early in premenopausal women. Postmenopausal women, who no longer get their periods, may not notice symptoms when the tumor is small. When a prolactinoma becomes large, it may press up against other nearby tissues.
Can you take medication for a premenopausal tumor?
When medical treatment works, most premenopausal women get their periods again and regain their fertility.
