How long can you take HRT? There is no set stop date

The old advice was to stop by a certain age. The Menopause Society now says that rule does not fit. Here is what replaced it, and how breast cancer risk changes with time.

For years, women heard some version of the same rule: take hormones for the shortest time possible, and stop by a certain age. Many women still try to stop after 4 or 5 years because they are worried about breast cancer [3]. The guidance has moved on. Today the question is less "how long am I allowed?" and more "do my benefits still outweigh my risks, this year?" Here is how that works.

There is no set stop age

The Menopause Society's 2022 position statement is direct. Because many women have bothersome hot flashes for many years, long-term hormone therapy may be needed, and an arbitrary age-based stopping rule is not clinically appropriate [1]. Its key points add that hormone therapy does not need to be routinely stopped in women older than 60 or 65 [1].

Where did the age-65 idea come from? The American Geriatrics Society's Beers criteria warn against hormone therapy in women over 65 [1]. But the statement notes that a recommendation to routinely stop at 65 is not supported by evidence, and is not recommended by either the American College of Obstetricians and Gynecologists or The Menopause Society [1].

The Menopause Society's patient guidance says the same thing in fewer words: there is no "right" time to stop [3]. In November 2025, the FDA also said that how long you use hormone therapy is a decision made between you and your prescriber [5].

Why the advice sounds mixed

You may still see older wording. The FDA's consumer page on menopause, last updated in 2023, advises using hormones at the lowest dose that helps and for the shortest time you need them [4]. MedlinePlus notes that experts are unclear on how long you should take hormone therapy, and that some professional groups suggest you can take it for menopause symptoms for longer periods [6]. A 2025 commentary in the British Journal of General Practice put it plainly: the optimal duration of use is unknown [7]. These are not really in conflict. "The time you need them" can be many years for some women, and the answer is meant to be personal.

Why some women need years, not months

Hot flashes are not a short phase for everyone. Frequent hot flashes last 7.4 years on average, and for many women more than 10 years [1]. In a study of Swedish women older than 85, 16% still reported hot flashes at least several times a week, and up to 8% of women keep having hot flashes 20 years or more after menopause [1].

That is why The Menopause Society says longer use should be for a documented reason, such as persistent hot flashes, with shared decision-making and periodic reevaluation [1]. For otherwise healthy women with persistent hot flashes, it calls continuing past 65 a reasonable option with counseling and regular review of benefits and risks [1]. Hormone therapy may also be considered to prevent fractures in healthy older women at higher fracture risk when other bone treatments do not work or are not tolerated [1].

What long-term hormone therapy is not for: reducing the risk of heart disease or dementia in older women [1].

Breast cancer and duration

This is the biggest reason women think about stopping, so it is worth getting the details right. The type of hormone therapy matters a lot.

Estrogen plus a progestogen

In the Women's Health Initiative (WHI), breast cancer risk became detectable after 3 to 5 years in women taking combined estrogen and progestin [1]. The attributable risk in that trial, where the average age was 63, was less than one additional breast cancer diagnosis per 1,000 users per year [1].

The largest look at duration comes from the Collaborative Group on Hormonal Factors in Breast Cancer, which pooled data from 108,647 postmenopausal women who developed breast cancer [2]. Among current users, the added risk was present even in years 1 to 4, and roughly twice as large in years 5 to 14 [2]. The authors then estimated what that could mean in absolute terms for women of average weight who start at 50 [2]:

Estimated chance of breast cancer between ages 50 and 69, after 5 years of hormone therapy from age 50, if the associations are largely causal [2]
Hormone therapyChance of breast cancer, ages 50 to 69
Never used6.3%
Estrogen plus a daily progestagen, 5 years8.3%
Estrogen plus a progestagen on some days only, 5 years7.7%
Estrogen alone, 5 years6.8%

The authors estimated the added risk from 10 years of use would be about twice as large [2]. Risk was higher in current users than in past users, but some extra risk persisted for more than 10 years after stopping, depending on how long women had used hormones [2]. There was little extra risk after less than a year of use, and vaginal estrogen was not linked to extra risk [2].

Two caveats. This was observational data, and the absolute estimates assume the link is largely causal [2]. And these numbers are averages; your own risk depends on your history.

Estrogen alone

For women without a uterus taking estrogen alone, the trial evidence is more reassuring. In the WHI, breast cancer risk did not increase after 7 years of estrogen alone, so The Menopause Society says longer use may be acceptable [1]. With a median of 20 years of follow-up, women assigned to estrogen alone had fewer breast cancer diagnoses than placebo [1]. That differs from the observational data above, which linked estrogen alone to a small increase [2]. The Menopause Society concludes that, given the more favorable safety profile of estrogen alone, longer durations may be more appropriate [1].

If you have a uterus, you need a progestogen with systemic estrogen to protect its lining [1], so estrogen alone is usually not an option. Our guide to progesterone without estrogen covers the progestogen side.

What the regular check-in involves

Instead of a stop date, the plan is ongoing review. For longer use, or use past 65, The Menopause Society recommends periodic reevaluation of other health conditions, with consideration of trial periods of lowering the dose or stopping [1]. It lists the factors that matter: how severe your symptoms are, how well non-hormone options work for you, and your underlying risk of osteoporosis, heart disease, stroke, blood clots, and breast cancer [1].

What you bring to each review
  • How your hot flashes and sleep are now
  • Any new bleeding, breast changes or side effects
  • Changes in your own or your family's health history
  • How you feel about continuing
What your clinician weighs
  • Whether the original reason still applies
  • Your risk of clots, stroke, heart disease and breast cancer
  • Bone health and fracture risk
  • Whether a lower dose or a non-oral route makes sense

Lowering risk as you age is part of the plan. The statement says using the lowest effective dose, and possibly a non-oral route, becomes increasingly important as women age and the longer they take hormones [1]. Options it names include switching from pills to transdermal (through the skin) estrogen, choosing a different progestogen, and lowering the dose [1]. Read more about the skin route in our estradiol patch guide.

There is honest uncertainty here. The WHI only tested 5 to 7 years of hormone therapy, so data on very long use are limited [1]. It is not known whether women who start at menopause and continue into older age carry the same risks as women who start hormones later in life [1].

Vaginal estrogen is a separate question

Low-dose vaginal estrogen, used for dryness and related symptoms, is treated differently. The Menopause Society says it may be used at any age and for an extended duration if needed [1]. See our vaginal estrogen cream guide.

When you do want to stop

Deciding to stop is just as personal as deciding to start. Do not stop or change your dose without talking with your provider first [6]. Hot flashes can come back, and there are choices to make about tapering. Our guide to stopping HRT walks through them.

Ongoing care at WarriorBabe Health

WarriorBabe Health clinicians revisit your plan over time, not just at the start. Our hormone treatments include oral estradiol, an estradiol patch, estradiol cream, and a progesterone capsule. Our hormone products are compounded by a licensed pharmacy and are not FDA-approved; FDA-approved versions also exist.

Frequently asked questions

Do you have to stop HRT at 65?

No. The Menopause Society says hormone therapy does not need to be routinely stopped at 60 or 65, and that routine discontinuation at 65 is not supported by evidence [1]. Continuing past 65 can be reasonable for healthy women with persistent hot flashes, with counseling and regular review [1].

Is it safe to take HRT for 10 years or more?

It depends on the type and on you. For combined estrogen and progestogen, breast cancer risk rises with longer use [1, 2]. For estrogen alone, WHI data are more reassuring [1]. Longer use should have a documented reason, like persistent hot flashes, and regular reassessment [1].

Does breast cancer risk go away after stopping HRT?

Risk is lower after stopping than during use, but it may not vanish right away. In a large pooled analysis, risk was higher in current users than past users, but some extra risk persisted for more than 10 years after stopping, depending on how long women had used hormones [2].

Why does my doctor say to use HRT for the shortest time?

That has long been standard wording. The FDA's 2023 consumer page still advises the shortest time you need hormones [4]. The Menopause Society's 2022 statement adds that for women with long-lasting symptoms, long-term use may be needed, and an arbitrary stopping age is not appropriate [1].

How often should my HRT be reviewed?

Regularly. The Menopause Society recommends periodic reevaluation of benefits and risks, and for longer use, periodic review of other health conditions with trials of lowering the dose or stopping [1]. Your clinician sets the schedule with you.
