Menopause & Midlife
Menopause Hormone Therapy: Benefits, Risks and Who It's For
Menopause hormone therapy (MHT), often still called HRT, is the most effective treatment for hot flashes and night sweats. It also prevents bone loss and treats vaginal dryness. According to The Menopause Society's 2022 position statement, for healthy women under 60 or within 10 years of menopause, the benefits generally outweigh the risks.
If you're in your late 40s or 50s, you've probably heard two completely different stories: "hormones cause cancer" from one friend, and "hormones changed my life" from another. Both are partly true. The risks are real, but they depend heavily on your age, when you start, your health history, and which hormones you use and how.
What it actually is
Hormone therapy replaces some of the estrogen your ovaries stop making. Two main types:
- Estrogen-only therapy (ET): for people who've had a hysterectomy (no uterus).
- Estrogen plus progestogen therapy (EPT): for people who still have a uterus. The progestogen (progesterone or a progestin) protects the uterine lining from overgrowth and cancer.
And several forms:
| Form | Examples | Notes |
|---|---|---|
| Oral | Pills | Passes through the liver first; linked to higher blood-clot risk than skin forms |
| Transdermal | Patch, gel, spray | Absorbed through the skin; observational data suggest lower clot and stroke risk |
| Vaginal (low dose) | Cream, tablet, ring | Treats vaginal and urinary symptoms; very little reaches the bloodstream |
| Combined/other | Estrogen with bazedoxifene; progestogen IUD | Options for protecting the uterus |
A practical note about patches: most people change them once or twice a week, and a common complaint is that they peel at the edges in summer or after the gym. Ask your pharmacist about placement tips if that happens.
Benefits and risks, side by side
| What it helps | What to weigh |
|---|---|
| Hot flashes and night sweats, better than any other treatment | Blood clots and stroke, higher with oral estrogen; transdermal appears lower-risk in observational studies |
| Sleep, when night sweats are what's waking you | Breast cancer: estrogen plus progestogen is linked to a small increase with longer use. Estrogen alone (after hysterectomy) didn't raise breast cancer risk in the WHI and may have lowered it. |
| Bone loss and fractures, including hip fractures | Endometrial cancer if you have a uterus and take estrogen alone, which is why a progestogen is added |
| Vaginal dryness and painful sex (low-dose vaginal estrogen is preferred if these are your only symptoms) | Gallbladder disease, mainly with oral estrogen |
| Mood in perimenopause for some people, though it isn't an approved depression treatment | Heart disease, stroke, clots and dementia when started late (after 60 or more than 10 years past menopause) |

If you went through early or premature menopause, hormone therapy is generally recommended until at least the average age of menopause to protect your bones, heart and overall health.
Why timing matters so much
The large Women's Health Initiative (WHI) studies, published starting in 2002, drove years of fear about hormones. Later analyses showed that risks differ a lot by age and timing. Most WHI participants were in their 60s, many years past menopause, which is not who usually starts hormones for hot flashes.
The Menopause Society's 2022 statement is built around that timing:
- Under 60, or within 10 years of menopause, with no contraindications: the benefit-risk balance is favorable for bothersome hot flashes and for preventing bone loss in those at higher risk.
- Starting at 60 or older, or more than 10 years after menopause: less favorable, because the absolute risks of heart disease, stroke, blood clots and dementia are higher.
This is about starting. If you began earlier and you're doing well, you may be able to continue past 60 after a careful review.
Who shouldn't take it?
Systemic hormone therapy usually isn't recommended if you have or have had:
- Breast cancer or another estrogen-sensitive cancer
- Unexplained vaginal bleeding
- Blood clots in the legs or lungs, or a known clotting disorder
- Stroke or heart attack
- Active liver disease
- Known or suspected pregnancy
Other conditions, like high triglycerides, migraine with aura or gallbladder disease, may push your clinician toward a specific form such as a patch, or toward non-hormonal treatment for hot flashes.
Questions people ask (and the straight answers)
"Should I take it to prevent heart disease or dementia?" No. The USPSTF recommends against hormone therapy for the primary prevention of chronic conditions like heart disease or dementia. It's for treating symptoms and, in selected people, preventing bone loss. It's not an anti-aging treatment.
"What about bioidentical hormones?" "Bioidentical" usually means hormones chemically identical to your own, like estradiol and micronized progesterone, and several FDA-approved products contain them. Custom-compounded bioidentical hormones are a different thing. The Menopause Society and ACOG don't recommend them routinely: they aren't FDA-approved, doses can be inconsistent, and they lack the same safety testing. Saliva hormone testing to adjust doses isn't recommended either.
"How long can I stay on it?" The Menopause Society says there's no reason to stop automatically at 65 or any other age. Use the lowest effective dose for your goals and review the decision with your clinician at least once a year. Some people stop after a few years; others continue because symptoms come back or they need bone protection. If you stop, ask whether to taper. Hot flashes can return either way.
"Why did the warning on my box change?" Estrogen products long carried a boxed warning based on the WHI. In November 2025, the FDA announced it would remove the boxed warnings about cardiovascular disease, breast cancer and probable dementia from menopause hormone therapy labels, and it approved the first updated labels in February 2026. A boxed warning about endometrial cancer remains for estrogen-only therapy in people who have a uterus. Labels are still being updated product by product, so the box in your cabinet may not match a friend's. Your clinician can explain the current wording.
Getting the most from your appointment
Menopause visits often get squeezed into a 15-minute annual exam. A few things help:
- Track symptoms for two weeks before you go: hot flashes per day, night wake-ups, mood, and anything that's changed in your period.
- Know your history: blood clots, migraines with aura, breast cancer in the family, your last mammogram date.
- Say what you want: "I'd like to talk about hormone therapy" gets a different conversation than "I'm tired."
- Ask directly: "Do you routinely prescribe and manage hormone therapy?" Not every clinician does, and it's fine to look for one who does.
When to see a doctor
Talk to a gynecologist, OB/GYN or women's health nurse practitioner if:
- Hot flashes, night sweats or lost sleep are affecting your life
- You went through menopause before 45 and aren't on hormone therapy
- You're on hormone therapy and notice new vaginal bleeding, leg swelling or pain, chest pain, shortness of breath, a severe headache or vision changes (get emergency care for chest pain, breathlessness or stroke signs)
- You want to review whether to continue or stop
Don't start, change or stop hormone doses on your own. To find someone who focuses on midlife care, see our guide to finding a menopause doctor in New York or browse gynecologists near you.
Frequently asked questions
Is hormone therapy safe for menopause?
For most healthy women who start hormone therapy before age 60 or within 10 years of menopause, The Menopause Society says the benefits outweigh the risks. Safety depends on your age, health history and the type of therapy.
What is the difference between HRT and MHT?
They mean the same thing. Many clinicians now say menopause hormone therapy (MHT), or just hormone therapy, instead of hormone replacement therapy (HRT).
How long can I stay on hormone therapy?
There's no set time limit. The Menopause Society says hormone therapy doesn't need to be stopped automatically at a certain age, but you and your clinician should review benefits and risks regularly.
Why do I need progesterone if I take estrogen?
If you have a uterus, estrogen alone can thicken the uterine lining and raise the risk of endometrial cancer. Adding a progestogen protects the lining.
Does hormone therapy cause weight gain?
Research hasn't shown that hormone therapy causes weight gain. Midlife weight changes are linked mainly to aging and lifestyle.
