Managing the menopause

Helen Roberts, senior lecturer women's health

The transition into the menopause usually begins with elongation of cycle length, the term postmenopausal being used after one year with no periods.1 Most women experience menopause between 40 and 58 years of age.1 No menopausal symptom is universal.w1 In Western society the commonest symptoms are hot flushes, night sweats, vaginal dryness, and sleep disturbance.2 Many women manage the menopause by themselves, with only about 10% seeking help from healthcare providers.2 Hormone replacement therapy is the most effective treatment for symptoms (table 11)3 and although opinions are still polarised advice on its use has changed after the women's health initiative studies.4

Table 1
 Grades of evidence for symptom relief at menopause


  • Hormone replacement therapy remains an appropriate treatment for women with moderate to severe menopausal symptoms
  • Hormone replacement therapy should not be used for the prevention of chronic disease
  • Treatment should be at the lowest dose for the shortest time necessary to control symptoms
  • Women should be advised of the increased risk of stroke, deep vein thrombosis, and gallbladder disease with both combined and oestrogen only therapy
  • Combined therapy is also associated with increases in risk of breast cancer and dementia (women aged >65)

Sources and selection criteria

This review is based on a search of Medline, the Cochrane Database of Systematic Reviews, and citation lists of relevant publications. The subject headings and key words used were “menopause”, “hormone replacement therapy”, “WHI”, “hot flushes”, “vaginal dryness”, “tibolone”, “testosterone”, and “complementary”.

What are the indications for hormone replacement therapy?

Menopausal symptoms

Indications for hormone replacement therapy are hot flushes, night sweats, and vaginal dryness (table 11).3 A Cochrane review of randomised trials showed a 75% reduction in flushes (18 fewer per week) with therapy compared with a 50% reduction with placebo.5

Flushes can start while a woman is still having periods. Her perception of severity of symptoms will be the deciding factor for offering treatment, not hormone levels, as they fluctuate throughout the perimenopause. Improvements can occur within four weeks of starting therapy.w2

Advice from most,3 6w3 w4 although not all, sources7 is to use the lowest dose of hormone for the shortest duration to give symptom relief. Short term use is also clinically appropriate as flushes disappear within a few years of menopause for about two thirds of women.6

Evidence from longitudinal studies does not suggest that mood symptoms are increased at menopause and at present information is insufficient to conclude any causal relation between the transition into menopause and cognitive disturbances.1 6 Disturbances in cognition and mood are not indications for hormone replacement therapy.

Urogenital symptoms are more common after the menopause and occur in up to 50% of women.6 Hormone replacement therapy makes incontinence worse, but vaginal oestrogen preparations benefit dyspareunia and decrease recurrent urinary tract infections in susceptible women (table 11).3 Response can take one or two months and as these symptoms are not usually self limiting long term use is needed. Systemic absorption is minimal so that the risks from oral oestrogen do not apply and women with a uterus do not need to use progestogen.6

Prevention of chronic disease

Long term hormone replacement therapy for the prevention of chronic disease is no longer recommended as negative outcomes outweigh positive benefits, as shown in both the oestrogen only and combined arms of the women's health initiative studies.8 The participants in the studies were women aged 50-79 using 0.625 mg conjugated equine oestrogen alone or with 2.5 mg medroxyprogesterone acetate. Results showed a statistically significant increase in stroke, deep vein thrombosis, and gallbladder disease for both the combined and oestrogen only treatments, with additional increases in breast cancer and dementia (women aged >65) for combined therapy (table 22).9 10 11 12 13 14 15 16 17 18 19 Statistically significant benefits were shown for fracture with both treatments and for colorectal cancer with combined therapy. Table 33 lists the differences in absolute risk.9 10 The risks are likely to be lower for healthy perimenopausal women using lower doses of hormone. These small increases in absolute risk for a few years are usually acceptable to women with troublesome symptoms.

Women with premature menopause usually have severe flushes requiring treatment and may often need higher doses of hormone.1 Evidence of other additional benefits is not substantial.6

What should women do about bone?

As bone density decreases with age, advice should be given on the benefits of adequate calcium, vitamin D,w5 and weight bearing exercise. Bone density screening for all menopausal women is not recommended; however, guidelines do support the assessment of osteoporosis risk at menopause and measurement of bone mineral density using dual energy x ray absorptiometry for those at risk. These are women aged more than 40 with fragility fractures, those using systemic glucocorticoids for more than three months, those aged less than 65 with risk factors (for example, family history of osteoporotic fracture), and those aged more than 65.20 If follow-up measurement of bone mineral density is necessary readings should be taken on the same machine to reduce precision error. Treatment should be considered for those with T scores below −2.5, or below −1.5 if one major clinical risk factor is present.20w6

As with previous studies, the women's health initiative studies showed a decreased risk of fracture with hormone replacement therapy.9 10 Most studies have shown that long term use is required for protection. Although agreement is not general,w7 most sources do not recommend long term treatment for osteoporosis because of the unfavourable risk_benefit ratio.3 21

In the women's health initiative studies, risks still outweighed the benefit for fracture even for those women at highest risk of fracture.w8 Bisphosphonates are recommended as first line treatment and with these the benefit for fracture has only been shown for women with osteoporosis(T score ≤2.5).6

What needs to be done before starting therapy?

A full personal and family history will highlight women with risk factors. Risk assessment for cardiovascular disease should include measurement of body mass index, blood pressure, and lipid levels. Women with previous breast cancer, coronary heart disease, stroke, dementia, or venous thromboembolism should not use hormone replacement therapy as randomised studies have shown an increased risk of further disease.6 22 Individualised risk can be assessed for women with risk factors for cardiovascular disease—that is, trial evidence can be translated to individual decisions by transforming relative risk into absolute risks. For example, hormone replacement increases the risk of stroke by 40% (relative risk 1.4). A woman with a 5% baseline risk then has a 7% (5×1.4) risk with hormone replacement therapy, which is only a 2% increase. If she has a 25% baseline risk, however, the risk with hormone replacement therapy is 35% (25×1.4), a 10% increase.23

How is hormone replacement given?

Oestrogen is available as oral tablets, transdermal patches or gels, nasal sprays, and implants, although availability differs across countries. Few clinical data are available to advise women about any different safety profile with hormones other than those used in the women's health initiative studies (conjugated equine oestrogens alone or with medroxyprogesterone acetate).

At present most women start with oral therapy at a low dose (0.3 mg conjugated equine oestrogen, 0.5-1.0 mg of 17-β-estradiol or estradiol valerate) as this has been shown to relieve flushes.w9 The dose can be increased if relief of symptoms is not adequate after a few weeks. Women who have had a hysterectomy can use unopposed oestrogen; the addition of progestogen is required for women with a uterus to reduce endometrial hyperplasia, which is increased even with low doses of oestrogen.w9 Combined continuous regimens (oestrogen and progestogen daily) can be used when the woman has been postmenopausal for more than one year; before this, sequential regimens (oestrogen daily with progestogen 10-14 days each month) are appropriate. Combined continuous regimens in early menopause may cause irregular bleeding, as oestrogen production from the ovaries is often still fluctuating. Use of prepacked products simplifies use; however, these may not yet be available in low dose format for all combined regimens and may mean that the hormones have to be prescribed individually. An easy rule of thumb to ensure adequate progestogen for protection of the endometrium is to extrapolate doses from those in prepackaged regimens. Low doses of progestogens such as norethisterone and levonorgestrel can be obtained from progestogen only pills.

For those women still menstruating, oestrogen should be started on the first day of the menstrual bleed and progestogen given 14 days later. Withdrawal bleeding should then start around the same time that the period would be expected.

Common side effects of hormone replacement therapy reported from randomised studies include irregular bleeding with combined regimens, which usually settles after a few months, and nausea and breast tenderness. These usually decrease over time, but in clinical practice lowering the dose of hormones reduces these side effects.5

Oestrogen can also be given by transdermal patch. Although transdermal oestrogen has little effect on haemostasis, further evidence is required before we can give advice on a lower thrombotic risk compared with oral oestrogen.

Oestrogen given by implant is usually best reserved for specialised centres. Women who have had an early surgical menopause and whose symptom relief with other means of administration is not adequate may find implants useful. Symptoms may return, however, despite super physiological levels of oestradiol (tachyphylaxis). Implants are not normally recommended for women who have a uterus, as prolonged stimulation of the endometrium may occur, requiring continuation of progestogen even after the implants are stopped.w10

Progestogen is available as an oral tablet, transdermal patch, or intrauterine system. The intrauterine system gives good protection of the endometrium and, unlike other combined hormone replacement therapies, offers both contraception and less bleeding for perimenopausal women.w11 w12

What are the bleeding patterns with hormone replacement therapy and how should irregular patterns be investigated?

Most women using the sequential regimen have a withdrawal bleed near the end of the progestogen dose. This is usually lighter than a period. Combined continuous regimens can give irregular spotting in the first 6-12 months of use, but at the end of the first year most women do not bleed. Endometrial investigation (ultrasonography to determine the thickness of the endometrium or pipelle biopsy) is not required before starting hormone replacement therapy unless there has been bleeding between periods or bleeding after one year with no periods.

If irregular bleeding persists during treatment compliance should be checked and cervical malignancy or infection ruled out before referring for investigation.

What advice can be given about stopping therapy?

Observational data show that for women starting hormone replacement therapy 40-50% stop within one year and 65-75% stop within two years, usually without needing to visit a healthcare provider.24 Good evidence is lacking on the best way to stop treatment. The initial approach could be to ask women to stop within one or two years of starting therapy to see if symptoms have gone. Women with severe return of flushes could then be advised to restart therapy but to slowly decrease the dose over the next 3-6 months. Addition of other non-hormonal treatments that help flushes has been suggested to help women who have symptoms during withdrawal, particularly those who are at high risk of adverse events while using therapy.6 24 Women with long term debilitating symptoms will need to balance symptom relief with ongoing risks from therapy.

Are there other treatments that can help menopausal symptoms?

The Royal College of Obstetricians and Gynaecologists advises that regular aerobic exercise such as swimming and running may help with flushes, as can reduction of caffeine and alcohol intake.25 Limited evidence also exists for acupuncture and for paced respirations.6

Tibolone, a synthetic steroid with weak oestrogenic, progestogenic, and androgenic properties, has shown benefit for flushes and vaginal dryness (table 11).). At present data are lacking from randomised studies to enable advice on outcomes such as breast cancer and cardiovascular disease.26

Randomised studies have shown that progestogens can benefit flushes (for example, Depo-Provera (Pharmacia) 150 mg (90% v 25% fewer flushes compared with placebo) or oral medroxyprogesterone acetate 20 mg daily (74% v 26% fewer flushes compared with placebo).27 These doses can be used in women with previous venous thromboembolism.

Progesterone cream (20 mg and 32 mg daily) has been evaluated in two randomised studies, one showing benefit (20 mg daily) for flushes (83% women improved v 19% placebo), the other not.w13 Data are insufficient to give assurance that progesterone cream will provide adequate protection of the endometrium for women using oestrogen.

Since the publication of the women's health initiative studies the use of bioidentical hormones for flushes has increased, usually in the form of transdermal creams or troches (similar to lozenges or pastilles). These are often a mixture of low doses of estradiol (0.5 mg) along with estriol (Biest cream) or also including estrone (Triest cream).These products are compounded in pharmacies and are not available commercially. Clinical efficacy for relief of flushes is likely to result from the estradiol component,w2 w9 and we have no data to advise women that risks are different from conventional hormone replacement therapy. Progestogen should be added to protect the endometrium in women with a uterus. Testing for hormones in saliva is often suggested with use of bioidentical hormones but is not thought to be useful.27 The treatments discussed for women with previous breast cancer are also the choices for other menopausal women with flushes.

What are the treatments for women with previous breast cancer?

Flushes are often severe for women with a history of breast cancer, either from the effects of chemotherapy and ovarian ablation or from the side effects of adjuvant therapy such as tamoxifen and aromatase inhibitors.28 One randomised study of hormone use in women with previous breast cancer showed an increase in recurrence compared with placebo.29 Any hormonal therapy, including progestogen alone, is considered to be contraindicated for women with previous breast cancer.

Clonidine has shown some benefit for flushes compared with placebo. Transdermal clonidine 0.1 mg/day seems to be more useful than oral clonidine (0.1 mg and 0.2 mg). Side effects include dry mouth, constipation, drowsiness, and dizziness, but no effect on blood pressure at these doses. Clonidine can, however, enhance the effects of other antihypertensives, anxiolitics, and alcohol.28

Both selective serotonin reuptake inhibitors and selective noradrenaline reuptake inhibitors have been shown to reduce flushes (60%) compared with placebo (30%), perhaps due to the role of serotonin in the pathophysiology of flushes. The benefit of these products over placebo can also be presented by the daily improvement in the number of flushes (table 44).30 Most of the randomised studies have been of short duration (4-12 weeks). Venlaflaxine (37.5 mg and 75 mg), fluoxetine (20 mg), and paroxetine (12.5 mg and 25 mg) have all shown benefit. Advice is to start at the lower doses and titrate upwards and also to taper the dose at withdrawal. Although these drugs are generally well tolerated, possible side effects include dry mouth, dizziness, nausea, and constipation. They also have the potential to decrease libido. At present there is discussion on the possible effects of selective serotonin reuptake inhibitors on the efficacy of tamoxifen. Tamoxifen is converted to its active metabolites by cytochrome P-450, and paroxetine, fluoxetine, and possible other selective serotonin reuptake inhibitors have potential to inhibit this conversion. Venlaflaxine would seem to be a weaker inhibitor.28

The anti-epileptic gabapentin (900 mg/day) has also been shown to provide benefit for flushes in women with breast cancer.30 The side effect profile may, however, restrict the use to specialised centres.25

Most of the studies of the herbal remedy black cohosh are of short duration, and have had mixed results. A recent randomised trial in women with breast cancer who were taking tamoxifen did, however, find benefit for flushes over placebo.6 The commercially available product Remifemin (GlaxoSmithKline, Pittsburgh, PA) has been the most widely studied. Although one case of acute hepatitis has been reported, overall the product seems safe for short term use.

Meta-analysis showed a small reduction in flushes from red clover isoflavones 40-82 mg/day.25 At present black cohosh and red clover are not thought to have any effects on breast or endometrium, although long term data are needed.

Other studies on phyto-oestrogens have shown mixed results, but the four trials in women with previous breast cancer found no difference in flushes with soy isoflavones compared with placebo.30 The effects on the breast of long term treatment with these products is not clear but they have been shown to cause endometrial hyperplasia.6

Vitamin E has shown a small benefit over placebo, with one less hot flush daily.25 Dehyroepiandrosterone, soy products, dong quai, evening primrose oil, or ginseng do not seem to benefit flushes.25 Replens (Meda, Solna, Sweden), a vaginal moisturiser, can be used for vaginal symptoms (table 11).w14

Testosterone replacement

The American Endocrine Society does not recommend the generalised use of testosterone in women.31 It points out that no data exist to advise women on risks from long term use. The main evidence of benefit for testosterone is for women with surgical menopause, when it was used along with hormone replacement. Improvement was found in sexual function compared with hormone replacement alone.w15 This meta-analysis had various modalities of replacement including testosterone implants and transdermal patches. The study lasted a median of six months, with the main adverse effect being a decrease in high density lipoprotein cholesterol levels.w15 Evidence of a treatment effect for perimenopausal women was insufficient. As testosterone is not approved for use in women in most countries, referral to specialised centres is advised.

What does the future hold?

Despite hormone replacement therapy being available for 60 years there are still many gaps in our knowledge. Ongoing longitudinal data on menopausal symptoms are needed for other ethnic groups. More research is needed on alternative therapies to tackle standardisation of dose, along with clinical efficacy. Larger randomised controlled trials for selective serotonin reuptake inhibitors and selective noradrenaline reuptake inhibitors are required to look at efficacy and the degree of interaction with tamoxifen.

It would be useful to have more information to advise women in the 50-59 years age group, who are the most likely users of hormone therapy for symptom relief. In the past few years subgroup analysis of results from the women's health initiative studies has been ongoing in this age group. The number of events is small, however, and the studies were not powered to examine them. Thus many of the reported interactions for these younger women may be spurious and due to chance alone.23 In this age group the only significant outcome (when the confidence interval did not include 1) was the increase in risk of deep vein thrombosis with combined replacement therapy (table 55).32 These subgroup analyses are, however, useful to generate hypotheses for much needed further study in these younger postmenopausal women. Some studies, such as the Kronos early estrogen prevention study,w16 are under way.
