From the Guidelines

Hormone therapy is not recommended as the primary treatment for postmenopausal bleeding due to the increased risk of cerebrovascular accidents, venous thromboembolic events, and breast cancer associated with its use. When considering medication treatment for postmenopausal bleeding, it is crucial to address the underlying cause.

  • For women with endometrial hyperplasia without atypia, progestin therapy such as medroxyprogesterone acetate (Provera) or a levonorgestrel intrauterine system (Mirena) may be prescribed, but the decision should be made with caution and careful consideration of the potential risks and benefits.
  • The use of hormone therapy, including estrogen plus progestin, has been associated with significant risks, as evidenced by high-quality studies such as those from the Women's Health Initiative 1, which showed an increased risk for cerebrovascular accidents and venous thromboembolic events.
  • In cases where hormone therapy is considered, the risks of invasive breast cancer, node-positive tumors, and deaths due to breast cancer should be carefully weighed against the potential benefits 1.
  • Alternative treatments, such as low-dose vaginal estrogen preparations for vaginal atrophy, may be considered, but only after thorough evaluation, including endometrial sampling to rule out endometrial cancer.
  • Treatment duration and follow-up should be tailored to the individual patient's symptoms and underlying pathology, with regular monitoring to ensure resolution of hyperplasia and minimize the risk of adverse effects.

From the FDA Drug Label

When estrogen therapy is prescribed for a postmenopausal woman with a uterus, progestin should also be initiated to reduce the risk of endometrial cancer. Use of estrogen-alone, or in combination with a progestin, should be with the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman. Adequate diagnostic measures, such as directed or random endometrial sampling, when indicated, should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.

The medication treatment of postmenopausal bleeding involves:

  • Estrogen therapy with progestin for women with a uterus to reduce the risk of endometrial cancer.
  • Using the lowest effective dose and for the shortest duration consistent with treatment goals and risks.
  • Diagnostic measures should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding 2.

From the Research

Medication Treatment of Postmenopausal Bleeding

  • The medication treatment of postmenopausal bleeding often involves the use of conjugated estrogens and medroxyprogesterone acetate to prevent endometrial hyperplasia, which can occur with conjugated estrogens alone 3.
  • Studies have shown that the incidence of endometrial hyperplasia is significantly lower in women treated with conjugated estrogens and medroxyprogesterone acetate than in women treated with conjugated estrogens alone 3.
  • Bleeding patterns in postmenopausal women taking continuous combined or sequential regimens of conjugated estrogens with medroxyprogesterone acetate have been compared, with results showing that the two continuous combined regimens produced amenorrhea in 61.4 and 72.8% of all evaluable cycles, respectively 4.
  • The use of micronized progesterone cyclical has been associated with fewer excess episodes of bleeding than medroxyprogesterone acetate continuous in the first 6 months of treatment 5.
  • The mechanisms of uterine bleeding in postmenopausal patients receiving estrogen alone or with a progestin have been studied, with results showing that cyclic estrogen and progestin therapy do not cause all the endometrium to desquamate to the basalis layer, and that the combination therapy is associated with increased glycoprotein production in the gland and stromal cells 6.
  • Clinical management of vaginal bleeding in postmenopausal women involves the diagnosis and treatment of underlying conditions, such as endometrial cancer, endometrial or cervical polyps, genital atrophy, or non-gynecologic conditions 7.

Treatment Options

  • Conjugated estrogens and medroxyprogesterone acetate are commonly used to treat postmenopausal bleeding, with the goal of preventing endometrial hyperplasia 3, 4.
  • Micronized progesterone cyclical may be a viable alternative to medroxyprogesterone acetate continuous, with fewer excess episodes of bleeding in the first 6 months of treatment 5.
  • The choice of treatment depends on the individual patient's needs and medical history, and should be guided by a healthcare professional 7.

Bleeding Patterns

  • Bleeding patterns in postmenopausal women taking hormone replacement therapy can vary depending on the regimen used, with continuous combined regimens producing amenorrhea in a significant proportion of patients 4.
  • The use of micronized progesterone cyclical has been associated with fewer excess episodes of bleeding than medroxyprogesterone acetate continuous 5.
  • Irregular and unpredictable breakdown of the endometrium can occur with cyclic estrogen alone, which may lead to hyperplasia and neoplasia 6.
