From the Guidelines

The treatment for galactorrhea caused by hyperprolactinemia typically involves dopamine agonist medications, with cabergoline being the preferred first-line option due to its superior effectiveness and lower adverse effect profile, as supported by recent guidelines 1. The goal of treatment is to normalize prolactin levels and resolve galactorrhea symptoms. Cabergoline is generally preferred over bromocriptine due to its fewer side effects and once or twice weekly dosing, starting at 0.25 mg twice weekly and gradually increasing if needed. Some key points to consider in the treatment of galactorrhea caused by hyperprolactinemia include:

  • Dopamine agonists, such as cabergoline, are the first-line treatment for hyperprolactinemia, with cabergoline being the preferred option due to its superior effectiveness and lower adverse effect profile 1.
  • Treatment duration depends on the underlying cause, with medication typically continued for at least 6 months before attempting to taper.
  • If a pituitary tumor (prolactinoma) is present, medication may be needed for years or indefinitely.
  • For medication-induced hyperprolactinemia, discontinuing the causative drug (such as antipsychotics, certain antidepressants, or metoclopramide) may resolve the condition.
  • Regular monitoring of prolactin levels is essential to assess treatment effectiveness, with the goal of normalizing prolactin levels and resolving galactorrhea symptoms.
  • Surgery may be considered for large prolactinomas that don't respond to medication or cause significant visual impairment, as well as radiotherapy in exceptional cases where other treatment modalities are not available or have been exhausted 1. It's also important to note that high-dose cabergoline may be effective in patients who are resistant to standard doses, with some studies suggesting that doses of up to 7 mg per week can be well tolerated and effective in treating prolactinomas 1. Overall, the treatment of galactorrhea caused by hyperprolactinemia should be individualized and based on the underlying cause, with careful monitoring and adjustment of treatment as needed to achieve optimal outcomes.

From the FDA Drug Label

Bromocriptine mesylate tablets, USP are indicated for the treatment of dysfunctions associated with hyperprolactinemia including amenorrhea with or without galactorrhea, infertility or hypogonadism The inhibition of physiological lactation as well as galactorrhea in pathological hyperprolactinemic states is obtained at dose levels that do not affect secretion of other tropic hormones from the anterior pituitary

The treatment for galactorrhea possibly caused by hyperprolactinemia is bromocriptine mesylate tablets, USP. This medication is indicated for the treatment of dysfunctions associated with hyperprolactinemia, including galactorrhea. It works by inhibiting the secretion of prolactin, which can help reduce the symptoms of galactorrhea. 2 2

Key points:

  • Bromocriptine mesylate tablets, USP are used to treat hyperprolactinemia-associated dysfunctions, including galactorrhea.
  • The medication inhibits the secretion of prolactin, which can help reduce the symptoms of galactorrhea.
  • Bromocriptine mesylate tablets, USP can be used to reduce tumor mass in patients with prolactin-secreting adenomas.

From the Research

Treatment for Galactorrhea

The treatment for galactorrhea, possibly caused by hyperprolactinemia, involves addressing the underlying cause of the condition.

  • Dopamine agonists, such as bromocriptine, pergolide, and cabergoline, are the treatment of choice for most patients with hyperprolactinemic disorders 3, 4, 5, 6.
  • These medications are effective in lowering serum prolactin levels, restoring gonadal function, decreasing tumor size, and improving visual fields 3.
  • Cabergoline is a preferred medication for the treatment of hyperprolactinemia due to its efficacy and better tolerability compared to bromocriptine 4, 5, 6.
  • However, cabergoline is not recommended as first-line therapy for patients seeking fertility due to limited safety data in pregnancy 3.
  • In some cases, surgical resection or radiation therapy may be necessary, particularly for patients with large lesions or those who cannot tolerate medical therapy 3, 4, 6.

Diagnostic Evaluation

The diagnostic evaluation for galactorrhea involves:

  • Excluding other causes of hyperprolactinemia, such as pregnancy, primary hypothyroidism, and medication use 3, 4, 5, 7, 6.
  • Measuring serum prolactin levels and performing a head scan, preferably an MRI, to exclude a pseudoprolactinoma or other sellar or suprasellar lesions 3, 4, 5, 7, 6.
  • Assessing thyroid and renal function, as hypothyroidism and chronic renal failure can also cause hyperprolactinemia 4, 5, 7, 6.

Management

The management of galactorrhea depends on the underlying cause and the severity of symptoms.

  • Patients with normoprolactinemic galactorrhea may not require treatment if the discharge is not bothersome 5, 6.
  • Medications contributing to hyperprolactinemia should be discontinued or replaced with alternative medications 4, 5, 6.
  • Patients with prolactinomas are usually treated with dopamine agonists, and surgery or radiation therapy is rarely required 3, 4, 5, 6.
