13<\/a>].<\/li><\/ul>\n\n\n\nStarting estrogen<\/strong> \u2014 <\/p>\n\n\n\n- Once a decision made to treat \u00e0 with estrogen,<\/li>
- consideration \u00e0 type of estrogen and<\/li>
- the route<\/li>
- need for progestin and the most appropriate progestin regimen.<\/li>
- Estrogen is available in many forms: oral, transdermal, topical gels and lotions, intravaginal creams and tablets, and vaginal rings.<\/li><\/ul>\n\n\n\n
Estrogen therapy (ET) remains the gold standard for relief of menopausal symptoms, in particular, hot flashes.<\/p>\n\n\n\n
Route<\/strong> \u2014 <\/p>\n\n\n\n- We start many women on transdermal 17-beta\u00a0estradiol<\/strong>\u00a0\u00e0 a lower risk of VTE, stroke, and hypertriglyceridemia than oral estrogens.<\/li>
- However, the baseline risk of both VTE and stroke is very low in otherwise healthy, young postmenopausal women.<\/li>
- Therefore, if a patient prefers an oral preparation over a transdermal one (cost or personal preference), we consider oral estrogen to be safe.<\/li>
- oral 17-beta\u00a0estradiol\u00a0<\/strong><\/li>
- All routes of estrogen administration \u00e0 equally effective for<\/strong> symptom relief (and bone density), but their metabolic effects differ:<\/strong><\/li>
- Oral estrogen \u00e0 more favorable effects on lipid profiles<\/li>
- In addition to oral and transdermal estrogen preparations, estrogen is available as a vaginal ring and as a topical spray, cream, or gel.<\/li><\/ul>\n\n\n\n
Dose<\/strong> \u2014 <\/p>\n\n\n\n- In the past, a “one-size-fits-all” approach<\/strong> to estrogen dosing was used, with oral conjugated estrogen (0.625\u00a0mg\/day)or its equivalent oral 17-beta\u00a0estradiol\u00a0(1\u00a0mg\/day),\u00a0or transdermal 17-beta estradiol (0.05 mg [50 mcg]), prescribed to most women.<\/li>
- However, the current approach is to start with lower doses<\/strong>, such as transdermal estradiol (0.025 mg) or oral estradiol (0.5\u00a0mg\/day),<\/strong>\u00a0and titrate up to relieve symptoms.<\/li>
- Lower doses are associated with less vaginal bleeding and breast tenderness<\/li>
- Lower doses are also associated with fewer effects on coagulation and inflammatory markers, and a possible lower risk of stroke and VTE than standard-dose therapy.<\/li><\/ul>\n\n\n\n
- Estrogen should be administered continuously<\/strong>; past regimens where estrogen was administered days 1 to 25 of the calendar month are considered to be obsolete.<\/li>
- Women will often get hot flashes during the days off, and there is no known advantage to stopping for several days each month.<\/li><\/ul>\n\n\n\n
Side effects<\/strong> \u2014 <\/p>\n\n\n\nCommon side effects of estrogen \u00e0<\/p>\n\n\n\n
- breast soreness, which can often be minimized by using lower doses.<\/li>
- some women experience mood symptoms and bloating with progestin therapy.<\/li>
- Vaginal bleeding occurs in almost all women receiving cyclic estrogen-progestin regimens and is common in the early months of a continuous estrogen-progestin regimen.<\/li><\/ul>\n\n\n\n
Adding a progestin<\/strong> \u2014 <\/p>\n\n\n\n- oral micronized\u00a0progesterone\u00a0\u00e0 first-line progestin.<\/li>
- All women with an intact uterus need a progestin in addition to estrogen to prevent endometrial hyperplasia, which can occur after as little as six months of unopposed ET.<\/li>
- Women who have undergone hysterectomy should not receive a progestin<\/strong>, as there are no other health benefits other than prevention of endometrial hyperplasia and carcinoma.<\/li><\/ul>\n\n\n\n
- The most extensively-studied formulation for endometrial protection is the synthetic progestin used in the WHI,\u00a0medroxyprogesterone acetate\u00a0(MPA) (2.5 mg daily).<\/strong><\/li><\/ul>\n\n\n\n
- While MPA is endometrial protective, it was associated with an excess risk of CHD and breast cancer when administered with conjugated estrogen in the WHI. In addition, regimens using continuous versus cyclic MPA may be associated with a higher risk of breast cancer.<\/li><\/ul>\n\n\n\n
- Our first choice of progestin is natural micronized\u00a0progesterone\u00a0(200\u00a0mg\/day\u00a0for 12\u00a0days\/month\u00a0or 100 mg daily). There are reasons to believe that natural progesterone might be safer for the cardiovascular system (no adverse lipid effects) and possibly the breast.<\/li><\/ul>\n\n\n\n
Side effects and bleeding<\/strong> \u2014 <\/p>\n\n\n\n- Some women are unable to tolerate cyclic progestin administration (with any type of oral progestin) because of mood side effects and bloating.<\/li>
- In addition, cyclic progestins almost always result in monthly withdrawal bleeding, which can be a lifestyle concern for many women.<\/li>
- For any of these concerns, we suggest switching to a continuous regimen.<\/strong> This often resolves the issue of mood symptoms and bloating. However, for women who are newly menopausal, breakthrough bleeding can be anticipated.<\/li><\/ul>\n\n\n\n
Women who cannot tolerate oral progestins<\/strong> \u2014 <\/p>\n\n\n\nSome women are unable to tolerate any oral progestin, whether given in a cyclic or continuous regimen. In this case, we sometimes suggest off-label use of the lower dose levonorgestrel-releasing intrauterine device (IUD)<\/strong>.<\/p>\n\n\n\nConjugated estrogen\/bazedoxifene<\/strong> \u2014 Another option is the combination of bazedoxifene, a selective estrogen receptor modulator (SERM), with conjugated estrogen.<\/strong><\/p>\n\n\n\n- the SERM bazedoxifene prevents estrogen-induced endometrial hyperplasia so that administering a progestin is not necessary.<\/li>
- Potential candidates include women with moderate-to-severe hot flashes who have breast tenderness with standard estrogen-progestin therapy (EPT) or women who cannot tolerate any type of progestin therapy because of side effects.<\/li>
- Like other SERMs, the risk of VTE is increased with bazedoxifene.<\/li><\/ul>\n\n\n\n
Duration of therapy<\/strong> \u2014 <\/p>\n\n\n\nFor women who choose estrogen or combined EPT, short-term use is suggested (generally not more than five years or not beyond age 60 years<\/strong><\/p>\n\n\n\nHowever, hot flashes persist for an average of 7.4 years, and many women continue to have symptoms for more than 10 years<\/p>\n\n\n\n
Monitoring with mammography<\/strong> \u2014 <\/p>\n\n\n\n- Routine mammograms and breast exams are recommended in women taking MHT, even when used short-term.<\/li><\/ul>\n\n\n\n
Use of oral contraceptives during the menopausal transition<\/strong> \u2014 <\/p>\n\n\n\n- A low-estrogen oral contraceptive (OC) is an option for perimenopausal women who seek relief of menopausal symptoms, who also desire contraception, and who in some instances need control of bleeding when it is heavy<\/li>
- Most of these women are between the ages of 40 and 50 years and are still candidates for OCs. For them, an OC containing 20 mcg of ethinyl\u00a0estradiol\u00a0provides symptomatic relief while providing better bleeding control than conventional MHT because the OC contains higher doses of both estrogen and progestin (which suppresses the hypothalamic-pituitary-ovarian axis).<\/li>
- OCs should be avoided in obese perimenopausal women because they are at greater risk for thromboembolism.<\/li><\/ul>\n\n\n\n
Stopping hormone therapy<\/strong> \u2014 <\/p>\n\n\n\nMany women have no trouble stopping estrogen<\/p>\n\n\n\n
However, abrupt withdrawal of exogenous estrogen at any age may result in the return of hot flashes and other menopausal symptoms.<\/p>\n\n\n\n
Tapering<\/strong> \u2014 <\/p>\n\n\n\nAlthough tapering MHT has not been proven to be more effective than stopping treatment abruptly, we suggest a gradual taper, particularly in women with a history of severe vasomotor symptoms.<\/p>\n\n\n\n
When tapering, one approach is to decrease the estrogen by one pill per week every few weeks (ie, six pills per week for two to four weeks, then five pills per week for two to four weeks, etc) until the taper is completed. The progestin is tapered on the same schedule.<\/p>\n\n\n\n
Implications of stopping<\/strong> \u2014 <\/p>\n\n\n\nThe implications of stopping EPT include:<\/p>\n\n\n\n
\u25cfReturn of estrogen deficiency symptoms is common.<\/p>\n\n\n\n
For women who experience recurrent, bothersome hot flashes after stopping estrogen, we initially suggest nonhormonal options before considering resuming estrogen<\/p>\n\n\n\n
\u25cfResumption of bone loss<\/p>\n\n\n\n
\u25cfDecrease in breast cancer risk<\/p>\n\n\n\n
\u25cfThe effect of estrogen cessation on CHD, particularly in young postmenopausal women, is unclear<\/p>\n\n\n\n
Extended use of MHT<\/strong> \u2014 <\/p>\n\n\n\nmenopausal hormone therapy (MHT) should be individualized and not discontinued solely based upon patient age.<\/p>\n\n\n\n
They suggest that extended use of MHT (beyond age 60 or even 65 years) may be reasonable when the clinician and patient agree that the benefits of symptom relief outweigh the risks<\/p>\n\n\n\n
For women who choose extended use of MHT (more than five years or beyond age 60 years), we restart estrogen at the lowest dose possible and make plans for a future attempt to stop the estrogen.<\/p>\n","protected":false},"excerpt":{"rendered":"
