Guide to Women's HRT: Menopause Hormone Therapy Explained

The Short Answer

Hormone replacement therapy (HRT) — increasingly called menopause hormone therapy — replaces the estrogen your ovaries stop producing around menopause, usually paired with progesterone if you still have a uterus. It's the most effective treatment for hot flashes and night sweats, and it comes in more forms (pills, patches, gels, vaginal creams) and through more channels (your OB/GYN, or a wave of menopause telehealth companies) than most women realize.

This guide explains what HRT actually is, who it's for, why it got an undeserved scare reputation in 2002, and who genuinely shouldn't take it. When you're ready to compare providers, see our ranking of women's HRT telehealth providers and our HRT cost guide.

What HRT Actually Is

HRT for menopause comes in two fundamentally different flavors:

Systemic HRT delivers estrogen into your bloodstream — via pill, patch, gel, or spray — to treat body-wide symptoms like hot flashes, night sweats, sleep disruption, and mood changes. If you still have a uterus, systemic estrogen is paired with progesterone (or a progestin). That's not optional: estrogen alone thickens the uterine lining and raises the risk of endometrial cancer, and progesterone protects against that. Women who've had a hysterectomy can typically take estrogen alone.

Local (vaginal) estrogen is a low-dose cream, tablet, or ring applied directly to vaginal tissue. It treats genitourinary symptoms — dryness, painful sex, urinary irritation — with very little absorption into the bloodstream. Because so little reaches circulation, many women who aren't candidates for systemic HRT can still use vaginal estrogen. It does not treat hot flashes.

Perimenopause vs. Menopause — and What HRT Treats

Perimenopause is the transition phase, often starting in the early-to-mid 40s, when hormone levels swing erratically. Periods become irregular; symptoms often start here and can be at their worst. Menopause is officially reached 12 months after your last period (average age 51 in the US), after which estrogen stays low.

The symptoms HRT treats best:

• Vasomotor symptoms — hot flashes and night sweats. HRT is the single most effective treatment available.
• Sleep disruption — often driven by night sweats, and frequently improves when they do.
• Mood changes — irritability, anxiety, and low mood that track the hormonal transition (HRT is not a treatment for clinical depression).
• Genitourinary syndrome of menopause (GSM) — vaginal dryness, painful sex, recurrent urinary symptoms. This is where local estrogen shines.

Delivery Formats Compared

Progesterone, for women with a uterus, is most commonly taken as an oral capsule (micronized progesterone) at bedtime — many women find it mildly sedating, which can be a feature.

"Bioidentical" vs. Synthetic, FDA-Approved vs. Compounded

You'll see "bioidentical" everywhere in menopause marketing. Here's the honest version: bioidentical simply means the hormone is chemically identical to what your body makes — and it's largely a marketing term, because plenty of FDA-approved, pharmacy-stocked products are already bioidentical. Estradiol patches, gels, and pills, and micronized progesterone capsules, are all bioidentical *and* FDA-approved.

The distinction that actually matters is FDA-approved vs. compounded:

• FDA-approved products are manufactured at standardized doses, tested for consistency, and stocked at any pharmacy.
• Compounded hormones are custom-mixed by compounding pharmacies. They can offer formats and doses that manufactured products don't (creams, unusual combinations), but they are not FDA-approved, aren't tested for batch consistency the same way, and are rarely covered by insurance.

Some telehealth providers build their model around compounded bioidentical formulations; others, like Alloy, explicitly use only FDA-approved products. Neither approach is a scam — but "bioidentical" on its own tells you nothing about quality, and mainstream medical organizations generally recommend FDA-approved products when one fits your needs.

Testosterone for Women

Testosterone isn't only a male hormone — women produce it too, and levels decline with age. Some women report improved libido on low-dose testosterone, and it's a fast-growing area of interest. But here's the honest state of play: there is no FDA-approved testosterone product for women in the US. Every female testosterone prescription is either an off-label fraction of a male product or a compounded formulation.

That's why availability is patchy. Among the six major menopause telehealth providers we track, only Midi Health currently prescribes testosterone for women (compounded, low-dose, in 25 states as of late 2025). Winona and Alloy state outright that they don't prescribe it; Winona offers DHEA as an alternative. Details in our provider ranking.

Why HRT Got a Scary Reputation (and What Changed)

In 2002, the Women's Health Initiative (WHI) — a massive federally funded trial — was halted early after reporting increased risks of breast cancer, heart disease, stroke, and blood clots in women taking a specific estrogen-plus-progestin pill. The headlines were alarming, prescriptions collapsed almost overnight, and a generation of women (and doctors) came to see HRT as dangerous.

The years since have brought a more careful reading. The average WHI participant was 63 years old — more than a decade past menopause — while real-world HRT users typically start in their late 40s or early 50s. Re-analyses gave rise to the timing hypothesis: for healthy women who start HRT within about 10 years of menopause and before age 60, the absolute risks are small and the benefit-risk balance is generally favorable. The trial also tested one specific oral formulation; today's transdermal estradiol and micronized progesterone have different risk profiles, particularly for blood clots.

None of this means HRT is risk-free, and the mainstream position isn't "everyone should take it." It's that for most healthy, symptomatic women near menopause, HRT is a reasonable, effective option — a view now reflected by The Menopause Society and other major medical bodies. The 2002 headline version simply overshot.

Side Effects and Who Shouldn't Take HRT

Common, usually mild side effects include breast tenderness, bloating, nausea, headaches, and irregular spotting — often settling within the first few months or resolving with a dose or format change.

HRT is generally not recommended for women with:

• A history of breast cancer or other estrogen-sensitive cancers
• A history of blood clots (DVT/pulmonary embolism) or clotting disorders
• Prior stroke or heart attack
• Unexplained vaginal bleeding (needs evaluation first)
• Active liver disease

This is exactly why every legitimate provider — telehealth included — screens your medical history before prescribing, and why "who shouldn't take it" is a conversation for a clinician, not a checklist.

Non-Hormonal Alternatives

If HRT is off the table or not your preference, real options exist. Low-dose SSRIs/SNRIs — including paroxetine, the first FDA-approved non-hormonal option for hot flashes — can meaningfully reduce vasomotor symptoms. Fezolinetant (Veozah), approved in 2023, is a newer non-hormonal drug that targets the brain pathway behind hot flashes directly. Several telehealth providers offer non-hormonal tracks alongside HRT.

The Bottom Line

HRT is the most effective treatment for menopause symptoms, the risks for healthy women near menopause are smaller than two decades of scary headlines suggested, and you now have more ways to access it than ever.
