When needed, galactorrhea treatment focuses on resolving the underlying cause.

Sometimes doctors can't determine an exact cause of galactorrhea. Your doctor might recommend treatment anyway if you have bothersome or persistent nipple discharge. In such instances, you might be given a medication to block the effects of prolactin or to lower the amount of prolactin in your body. Reducing the prolactin level in your body may eliminate galactorrhea.

Underlying cause Possible treatment
Medication use Stop taking medication, change dose or switch to another medication. Make medication changes only if your doctor says it's OK to do so.
Underactive thyroid gland (hypothyroidism) Take a medication, such as levothyroxine, to counter insufficient hormone production by your thyroid gland (thyroid replacement therapy).
Pituitary tumor (prolactinoma) Use a medication to shrink the tumor or have surgery to remove it.
Unknown cause Try a medication to lower your prolactin level, such as bromocriptine (Parlodel, Cycloset) or cabergoline, and minimize or stop milky nipple discharge. Side effects of these medications commonly include nausea, dizziness and headaches.
