What is the recommended hormone replacement therapy (HRT) regimen for menopause?

From the Guidelines

The recommended hormone replacement therapy (HRT) regimen for menopause typically includes estrogen alone for women without a uterus, or estrogen plus progestogen for women with an intact uterus to protect against endometrial cancer, with treatment starting at the lowest effective dose and individualized based on symptom severity, as supported by recent research 1.

Key Considerations

• Estrogen options include oral estradiol (0.5-1mg daily), transdermal estradiol patches (25-100mcg/day), or conjugated equine estrogens (0.3-0.625mg daily) [ 1 ].
• For women with a uterus, progestogen options include micronized progesterone (100-200mg daily), medroxyprogesterone acetate (2.5-5mg daily), or levonorgestrel in combination products.
• HRT is most effective for vasomotor symptoms like hot flashes and night sweats, and also helps with vaginal dryness and bone protection.
• For women primarily experiencing vaginal symptoms, low-dose vaginal estrogen products may be preferable.

Duration and Risks

• HRT is generally recommended for the shortest duration needed for symptom relief, typically 2-5 years, though longer use may be appropriate for some women after discussing risks and benefits with their healthcare provider [ 1 ].
• The timing hypothesis suggests that menopausal hormone therapy has a beneficial effect on blood pressure and cardiovascular outcomes if initiated during a certain time window around menopause in women with risk factors, with a limited treatment duration of 5 to 10 years [ 1 ].

Clinical Guidelines

• Clinical guidelines agree on the (peri)-menopausal use of combined estrogen-progestin therapy (for women with an intact uterus, or estrogen use for women with a history of hysterectomy) with early menopause or premature ovarian insufficiency [ 1 ].
• Primary cardiovascular prevention with menopausal hormone therapy in healthy perimenopausal women is a matter of ongoing debate [ 1 ].

From the FDA Drug Label

When estrogen is prescribed for a postmenopausal woman with a uterus, a progestin should also be initiated to reduce the risk of endometrial cancer. A woman without a uterus does not need progestin 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. For treatment of moderate to severe vasomotor symptoms, vulval and vaginal atrophy associated with the menopause, the lowest dose and regimen that will control symptoms should be chosen and medication should be discontinued as promptly as possible. The usual initial dosage range is 1 to 2 mg daily of estradiol adjusted as necessary to control presenting symptoms.

The recommended Hormone Replacement Therapy (HRT) regimen for menopause is to use the lowest effective dose of estrogen, alone or in combination with a progestin (for women with a uterus), for the shortest duration necessary to control symptoms. The usual initial dosage range is 1 to 2 mg daily of estradiol, adjusted as necessary to control presenting symptoms, and administered in a cyclic regimen (e.g., 3 weeks on and 1 week off) 2. Key considerations include:

• Using the lowest effective dose to minimize risks
• Combining estrogen with progestin for women with a uterus to reduce the risk of endometrial cancer
• Reevaluating treatment periodically (e.g., every 3-6 months) to determine if it is still necessary
• Discontinuing medication as promptly as possible when symptoms are controlled

From the Research

Recommended HRT Regimen for Menopause

The recommended hormone replacement therapy (HRT) regimen for menopause varies depending on the individual's needs and medical history. According to 3, HRT is considered the gold standard for managing vasomotor and vaginal symptoms of menopause.

• Key considerations for prescribing HRT include:
  • Cyclic vs continuous administration
  • Tapering therapy
  • Estrogen dosage forms, such as injections and transdermal formulations
  • Combination with progestin or bazedoxifene for women with an intact uterus to minimize malignancy risk

Low-Dose HRT

Low-dose HRT has been shown to be effective for relieving vasomotor symptoms, preventing bone loss, and reducing the risk of breast cancer 4, 5, 6.

• Benefits of low-dose HRT include:
  • Reduced risk of side effects
  • Improved compliance rates
  • Effective for reducing hot flashes and improving vaginal atrophy
  • Favorable effects on lipid and lipoprotein patterns

HRT Regimens

Different HRT regimens are available, including continuous combined HRT and sequential combined HRT 7.

• Factors to consider when selecting an HRT regimen include:
  • Patient's individual needs and medical history
  • Dosage and route of administration
  • Schedule of administration
  • Potential risks and benefits of each regimen

Individualized Approach

An individualized approach to HRT is recommended, taking into account the patient's unique needs and medical history 7.

• This approach considers both the benefits and risks of treatment, as well as the patient's preferences and lifestyle.
