What HRT does
Estrogen levels fall at menopause. HRT gives back estrogen to ease symptoms. MedlinePlus lists fewer hot flashes and night sweats, and relief from sleep problems, vaginal dryness, anxiety and mood swings.
MedlinePlus notes HRT was once used to help prevent bone thinning (osteoporosis), and that other medicines can now treat it. It also says studies show HRT doesn't help treat heart disease, urinary incontinence or dementia.
Types of HRT and estrogen
| Type | Who it's for | Common forms |
|---|---|---|
| Estrogen plus progestogen (combination) | Women with a uterus; the progestogen protects the uterine lining | Pills, skin patches |
| Estrogen alone | Usually women who've had a hysterectomy | Pills, patches, gel, spray, vaginal ring |
| Progestogen alone | Added to estrogen for women with a uterus | Pills, IUD and other forms |
| Vaginal (local) estrogen | Vaginal dryness and pain with sex | Cream, tablet, insert, ring |
- Systemic vs local. Pills, patches, gels and sprays reach the whole body and relieve hot flashes. Vaginal products use much lower doses and mainly help vaginal symptoms.
- Patches vs pills. MedlinePlus notes skin patches carry less blood clot and stroke risk than pills, because they avoid passing through the liver first.
- Bioidentical hormones closely match the body's own estrogen and progesterone, and several are FDA-approved. Cleveland Clinic notes compounded bioidentical hormones are not well studied, so many clinicians don't recommend them.
Compounded medications aren't FDA-approved. A licensed clinician decides what's right for you.
Who should not take HRT
MedlinePlus and Cleveland Clinic list these as reasons a clinician usually advises against HRT:
- Breast, uterine (endometrial) or ovarian cancer, now or in the past
- Blood clots in the legs or lungs, or a high risk of clots
- A past stroke or heart attack, or high heart disease risk
- Liver disease or gallbladder disease
- Unexplained vaginal bleeding
- Pregnancy
Call your clinician about any vaginal bleeding after menopause. Call 911 for chest pain, sudden shortness of breath, a painful swollen leg, or signs of a stroke such as face drooping, arm weakness or trouble speaking.
What changed in the FDA warnings
On November 10, 2025, the FDA asked makers of menopausal hormone therapy to remove heart disease, breast cancer and probable dementia statements from the boxed warning, and to add that starting systemic therapy can be considered for women under 60 or within 10 years of menopause with moderate to severe hot flashes. By February 12, 2026, the FDA listed the first six products with updated labels.
The heart disease and breast cancer warnings stay in the main safety section of systemic products, and systemic estrogen-alone products keep a boxed warning for uterine cancer in women with a uterus. The change makes HRT easier to discuss, not risk-free.
Deciding and getting started
- List your symptoms and how much they affect sleep, work and relationships.
- Share your history: cancers, clots, stroke, heart and liver health, and whether you still have a uterus.
- Ask about forms: patch vs pill, systemic vs vaginal only.
- Agree on follow-up and when to reassess.
If your clinician orders an estradiol test, untreated estradiol after menopause is normally low, and that is expected. The optimal estradiol range in the table below for postmenopausal women applies only to women already on estradiol therapy. Read the estradiol lab guide.

Common questions
Is HRT safe for menopause?
MedlinePlus says HRT is safest when started before 60 or within 10 years of menopause, and overall death rates are lower in women who start then. Risks such as clots, stroke and breast cancer depend on your history, the type and the form.
Who should not take HRT?
Women with a history of breast or uterine cancer, blood clots, stroke or heart attack, liver disease, unexplained vaginal bleeding, or who are pregnant are usually advised against it.
Do I need progesterone with estrogen?
If you still have a uterus, usually yes. A progestogen protects the uterine lining from cancer risk with estrogen.
Is a patch safer than a pill?
Patches carry less blood clot and stroke risk than pills, according to MedlinePlus. Your clinician helps choose.
Did the FDA remove the black box warning on HRT?
Partly. Since November 2025 the FDA has been removing heart disease, breast cancer and dementia statements from the boxed warning; the uterine cancer boxed warning stays for systemic estrogen-alone products.
