During Women's Health Awareness Month, it is crucial to address menopause-related issues with informed strategies. The prevalence of vasomotor symptoms of menopause ranges from 50% to 82% among US women experiencing natural menopause. Additionally, genitourinary syndrome of menopause affects 27% to 84% of postmenopausal women. Breast cancer impacts approximately one in eight women in the US. 

In this article, we dive into a comprehensive analysis of major clinical practice guidelines and other guidance documents published by the North American Menopause Society (NAMS), American College of Obstetricians and Gynecologists (ACOG), Endocrine Society (ES), American Association of Clinical Endocrinologists (AACE), and American College of Endocrinology (ACE). By comparing and contrasting their approaches, we aim to shed light on best practices for the diagnosis and management of symptoms of menopause, highlighting the importance of harmonized guidelines to ensure effective and compassionate care for women undergoing menopause

Guideline Similarities

The following are agreed upon in the current guidelines:

For GSM:

  • the need for healthcare providers to take the initiative and ask about GSM
  • using the opportunity when women present during the menopausal transition to perform evaluation and assessment
  • evaluation of GSM should include screening, history taking, and physical examination
  • over-the-counter (OTC) non-hormonal vaginal lubricants and moisturizers as the first-line treatment for GSM for women with or without breast cancer versus an informed-consent discussion of breast cancer risk for women who prefer hormone therapy
  • low-dose vaginal estrogen, ospemifene, vaginal moisturizers, and lubricants as effective therapy for those choosing non-hormonal therapy
  • local hormone therapy for the treatment of women with only vaginal symptoms without vasomotor symptoms
  • education about GSM
  • the importance of communicating the potential benefits and risks of hormone therapy and other therapies with the patients.

For menopausal vasomotor symptoms:

  • Systemic hormone therapy (HT), also called menopausal hormone therapy (MHT), is the most effective therapy.
    • Before starting HT, healthcare providers should screen women for cardiovascular and breast cancer risk.
    • Healthcare providers should individualize care when prescribing HT.
    • For women aged younger than 60 years or who are within 10 years of menopause and have no contraindications, the benefit-risk ratio is favorable for the treatment of bothersome VMS and also for the prevention of bone loss.
    • For women who initiate hormone therapy more than 10 years from menopause onset or who are older than 60 years, the benefit-risk ratio appears less favorable. Longer durations of therapy should be for documented indications such as persistent VMS, with shared decision-making and regular reevaluation.
  • Data do not show that herbal supplements are efficacious.

Guideline Differences

Potential Reasons for Differences

  • Differences in the specific scope of each guideline—menopausal vasomotor symptoms, or GSM.
  • Some guidance documents are created by a single society and others by a collaboration between societies.
  • Differences in the methodology used to formulate the recommendations.
  • The publication dates.
  • The target population — menopausal women with or without risk of breast cancer.

Specific Guideline Differences

  • The term GSM is new, so it is not used in older guidelines (before 2015)
  • For treatment of GSM in women with or at risk of breast cancer, NAMS/ISSWSH recommends the use of local hormone therapy for some women who fail nonhormone treatments after a discussion of risks and benefits and review with a woman’s oncologist. In women who present with symptomatic GSM with a history of breast or endometrial cancer that does not respond to nonhormonal therapies, ES suggests a shared decision-making approach that includes the oncologist to discuss using low-dose vaginal ET. While NAMS 2020 reported that there is insufficient data at the time of publication to confirm the safety of vaginal estrogen or DHEA or ospemifene in women with breast cancer, the management of GSM should consider the recommendations of her oncologist.
  • NAMS 2023 does not recommend cooling techniques, but ACOG recommends common sense lifestyle modification such as clothing layering, maintaining a lower ambient temperature, and drinking cool drinks. Also, ES recommends turning down the thermostat and dressing in layers.

General Comparison of Key Conclusions in Each Guideline

NAMS 2020

  • Nonhormone therapies without a prescription provide sufficient relief for most women with mild symptoms.
  • Low-dose vaginal estrogens, vaginal DHEA, systemic estrogen therapy, and ospemifene are effective for moderate to severe GSM.
  • When low-dose vaginal estrogen, DHEA, or ospemifene is administered, a progestogen is not indicated. However, endometrial safety has not been studied in clinical trials beyond 1 year.
  • There is insufficient data to confirm the safety of vaginal estrogen, DHEA, or ospemifene in women with breast cancer.
  • The management of GSM should consider the woman’s needs and include a discussion with her oncologist.

NAMS/ISSWSH

  • Nonhormone treatments generally are the first line.
  • Local hormone therapies may be an option for some women who fail non-pharmacologic and non-hormone treatments after a discussion of risks and benefits and review with an oncologist.

ACOG

  • Systemic HT is the most effective therapy for vasomotor symptoms related to menopause.
  • Low and ultra-low systemic doses of estrogen are associated with a better adverse effect profile.
  • HT treatment with the lowest effective dose for the shortest duration that is needed to relieve vasomotor symptoms is recommended.
  • The risks of combined systemic HT include thromboembolic disease and breast cancer.
  • SSRIs, SSNRIs, clonidine, and gabapentin are effective alternatives for the treatment of menopausal vasomotor symptoms.
  • Estrogen therapy alleviates atrophic vaginal symptoms.
  • Local therapy is advised for the treatment of women with only vaginal symptoms.
  • Paroxetine is the only nonhormonal therapy that is approved by the FDA for the treatment of vasomotor symptoms.
  • The FDA approved ospemifene for treating moderate-to-severe dyspareunia in postmenopausal women.

ES

  • Menopausal hormone therapy is the most effective treatment for vasomotor symptoms and other symptoms of the climacteric.
  • Benefits may exceed risks for the majority of symptomatic postmenopausal women who are under age 60 or under 10 years since the start of menopause.
  • Healthcare professionals should individualize therapy.
  • Women should be screened for cardiovascular and breast cancer risk before initiating MHT.
  • Current evidence does not justify the use of MHT to prevent coronary heart disease, breast cancer, or dementia.
  • Other options are available for those with vasomotor symptoms who prefer not to use MHT or who have contraindications.
  • Low-dose vaginal estrogen and ospemifene provide effective therapy for the genitourinary syndrome of menopause; vaginal moisturizers and lubricants are available for those not choosing hormonal therapy.
  • All postmenopausal women should embrace appropriate lifestyle measures.

AACE/ACE

  • The use of menopausal hormone therapy in symptomatic postmenopausal women should be based on consideration of all risk factors for cardiovascular disease, cancer, osteoporosis, age, and time from menopause.
  •  The use of transdermal as compared with oral estrogen preparations may be considered less likely to produce thrombotic risk and perhaps the risk of stroke and coronary artery disease.
  • When the use of progesterone is necessary, micronized progesterone is considered the safer alternative.
  • In symptomatic menopausal women who are at significant risk from the use of hormone replacement therapy, the use of selective serotonin re-uptake inhibitors and possibly other nonhormonal agents may offer significant symptom relief.
  • In women with previously diagnosed diabetes, the use of HRT should be individualized.

NAMS 2022

  • Hormone therapy remains the most effective treatment for vasomotor symptoms and the genitourinary syndrome of menopause.
  • The risks of hormone therapy differ.
  • The benefit-risk ratio is favorable for treatment of bothersome VMS and prevention of bone loss in women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications, Nevertheless, treatment should be individualized.
  • For women who start hormone therapy more than 10 years after menopause or who are older than 60 years, the benefit-risk ratio appears less favorable.
  • If GSM symptoms are not relieved with over-the-counter therapies in women without indications for the use of systemic hormone therapy, low-dose vaginal estrogen therapy or other treatment (e.g., vaginal dehydroepiandrosterone or oral ospemifene) are recommended.

NAMS 2023

  • Hormone therapy is the most effective treatment for vasomotor symptoms and should be considered in menopausal women within 10 years of the last menstrual period.
  • For women who are not candidates for hormone therapy or personal preference, nonhormone treatment options are available.
  • Examples: cognitive-behavioral therapy, clinical hypnosis, selective serotonin reuptake inhibitors/ serotonin-norepinephrine reuptake inhibitors, gabapentin, fezolinetant; oxybutynin; weight loss, stellate ganglion block.

Management

  • The genitourinary syndrome of menopause (GSM) was covered in six guidance documents and the vasomotor symptoms were covered in five guidance documents.  The management recommendations for each are summarized in the following two tables.

Specific Management Recommendations for GSM/vaginal symptoms

Specific Management Recommendations for Vasomotor Symptoms

Key Takeaways

  • Screening and assessment of GSM should consist of history taking, physical examination, and excluding similar conditions.
  • Counseling patients about treatment options for GSM should include shared decision-making.
  • First-line non-hormonal treatment to alleviate the symptoms of mild GSM includes over-the-counter (OTC) nonhormone vaginal lubricants and moisturizers.
  • Low-dose vaginal estrogen and ospemifene provide effective therapy for the GSM of menopause.
  • For vasomotor symptoms, menopausal hormone therapy (MHT)/systemic hormone therapy (HT) with estrogen alone or in combination with progestin is the most effective treatment.
  • Before initiating MHT, healthcare providers should screen women for cardiovascular and breast cancer risk.
  • Other options are available for those with vasomotor symptoms who should not or wish not to take MHT.
  • For women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications, the benefit-risk ratio is favorable for treatment of bothersome VMS and prevention of bone loss.
  • For women who start hormone therapy more than 10 years from menopause onset or who are older than 60 years, the benefit-risk ratio appears less favorable because of the greater risks of coronary heart disease, stroke, venous thromboembolism, and dementia.
  • In breast cancer patients, fluoxetine and paroxetine should not be used, as they inhibit the effect of tamoxifen. Other guidelines recommend experiencing caution of paroxetine in patients taking tamoxifen.
