HRT for Menopause
Medically reviewed by Kindr Health Clinical Team · Last reviewed July 3, 2026
Hormone replacement therapy (HRT) is the most effective treatment we have for the symptoms of menopause — hot flashes, night sweats, vaginal and urinary changes, sleep disruption, and bone loss. It is also one of the most misunderstood. The WHI trial in 2002 scared a generation of women away from it; two decades of better data have refined who benefits, who does not, and how to deliver it safely. This is the straight version: what HRT is, what it actually does, the real risks (not the headline version), and how it is prescribed today.
Hormone replacement therapy (also called menopausal hormone therapy, MHT) replaces the estrogen — and usually progesterone — that the ovaries stop producing at menopause. The goal is to relieve symptoms caused by that hormone loss and, for some women, to protect bone and cardiovascular health during the transition.
"HRT" is an umbrella term. What you actually take depends on your body: whether you have a uterus, whether your main symptoms are systemic (hot flashes) or local (vaginal dryness), your personal and family risk profile, and your preferences. Two women in menopause can be on completely different regimens — both correct.
Estrogen alone (ET) — for women without a uterus. Typically estradiol delivered transdermally (patch, gel, or spray) or orally.
Estrogen plus progestogen (EPT) — for women with a uterus. The progestogen (micronized progesterone or a synthetic progestin) protects the endometrium from estrogen-driven overgrowth. This is the combination most perimenopausal and menopausal women use.
Local vaginal estrogen — low-dose cream, tablet, or ring applied directly to vaginal tissue for GSM. It is not "systemic HRT": serum estradiol stays in the postmenopausal range, so it carries a different risk profile and is appropriate at any age, including for women who cannot take systemic estrogen.
Oral estrogen passes through the liver first (first-pass metabolism), which increases clotting factors and triglycerides. Transdermal estrogen (patch, gel, spray) bypasses the liver and avoids that effect. Large observational data, including the BMJ study of over 80,000 women, found transdermal estrogen carried a substantially lower VTE risk than oral.
For most women starting systemic HRT, transdermal estradiol is the preferred first route — lower clot risk, stable levels, and easy dose adjustment. Oral remains reasonable for some women (e.g., cost, preference, or specific absorption considerations).
The progestogen also matters: micronized progesterone (bio-identical, brand Prometrium) appears to carry a more favorable breast and cardiovascular profile than older synthetic progestins, per the E3N cohort data.
The strongest evidence supports HRT for women who are within 10 years of menopause onset or under age 60, with no specific contraindications. In that window, the benefits (symptom relief, bone protection, and for some women cardiovascular and metabolic benefit) generally outweigh the risks.
HRT is appropriate for bothersome symptoms — you do not have to "just suffer through." The decision is clinical, based on your symptom severity, history, and risk profile, not on an arbitrary age cutoff.
Women with premature or early menopause (before 45, especially before 40) are generally advised to take HRT until the average age of menopause (51), because the long-term estrogen gap raises osteoporosis and cardiovascular risk.
Blood clots (VTE): oral estrogen increases VTE risk roughly 2-3x; transdermal estrogen does not show the same increased risk in observational data. This is why transdermal is the preferred starting route for most women.
Stroke: oral estrogen is associated with a small increase in stroke risk, primarily in older women or those with baseline vascular risk. Transdermal shows a more favorable profile.
Breast cancer: combined estrogen-plus-progestin therapy is associated with a small increase in breast cancer risk with longer-term use (the signal is stronger with synthetic progestins than with micronized progesterone). Estrogen alone (for women without a uterus) has not shown the same increased risk in the WHI follow-up. Duration, formulation, and personal/family risk all weigh in.
The 2002 WHI results that caused widespread fear reflected an older population (average age 63), often started on HRT well past the timing window, using formulations (oral conjugated equine estrogen plus a synthetic progestin) that are not what most women are prescribed today. Modern prescribing — transdermal estradiol, micronized progesterone, started within the window — is a different risk profile.
You complete an online intake covering symptoms, history, and risk factors. A board-certified menopause provider reviews it, typically within 24-72 hours, and prescribes when clinically appropriate.
Most members start on transdermal estradiol plus micronized progesterone (if they have a uterus), or local vaginal estrogen for GSM. Medications are compounded by an FDA-registered pharmacy or dispensed as FDA-approved products, shipped discreetly, with most included in the $79/month membership.
Ongoing care is built in: message your care team, monthly auto-refills, and dose adjustments whenever your body needs them. Follow-up is not an extra appointment — it is part of the plan.
For most women within 10 years of menopause or under 60, without specific contraindications, the benefit-risk balance is generally favorable. Safety depends on your personal history, the formulation, the route (transdermal is preferred), and the duration. It is a clinical decision, made with a provider, not a blanket yes or no.
NAMS no longer recommends an arbitrary stopping age. Duration is individualized based on symptoms, risk profile, and preference. Many women stay on HRT for 5-10+ years. The decision to continue is revisited with your provider over time.
No. There is no evidence HRT causes weight gain. Some women lose a small amount of visceral fat, and improved sleep and mood often make healthy habits easier.
"Bioidentical" means the hormone is structurally identical to what your body produces (e.g., estradiol, micronized progesterone) — many of these are FDA-approved. "Compounded" means made by a compounding pharmacy. Kindr uses both FDA-approved bioidentical products and compounded formulations from FDA-registered pharmacies when clinically appropriate. We do not recommend unregulated, untested compounded hormone regimens.
Yes — women without a uterus typically take estrogen alone (no progestogen needed), which carries a more favorable risk profile. See our page on HRT after hysterectomy.
Non-hormonal options exist and work: fezolinetant (Veozah) and low-dose paroxetine (Brisdelle) for hot flashes, and local vaginal estrogen remains appropriate even when systemic estrogen is contraindicated. Your Kindr provider helps you choose.
