Transdermal & oral estradiol
The most effective treatment for hot flashes and night sweats.
VIDEO LESSON
How it's taken
• Patch: changed once or twice a week
• Gel or spray: applied to the skin daily
• Tablet: once daily
• With a uterus, always paired with a progestogen
Side effects at a glance
• Breast tenderness, bloating, headache or spotting in the first months
• Skin irritation with patches
Rare but serious
• Blood clots and stroke, lower with transdermal than oral forms in observational studies
• Endometrial cancer if estrogen is used without a progestogen in a person with a uterus
Monitoring
A yearly review of symptoms, dose and goals. Report unexpected bleeding. Keep up with mammograms. Blood estradiol levels are not needed for routine dosing.
Good to know
Skin forms skip first-pass liver metabolism, which is why they are preferred with migraine, obesity or higher clot risk.

MECHANISM
How it works
Replaces the estradiol the ovaries stop making. Given as a patch, gel, spray or tablet, it binds estrogen receptors in the brain’s temperature center, bone, blood vessels and genitourinary tissue. Women who still have a uterus also need a progestogen to protect the uterine lining.
THE EVIDENCE
What the research actually shows.
EVIDENCE SUMMARY
Systemic estrogen is the most effective therapy for hot flashes and night sweats, and it prevents bone loss and fracture. The Menopause Society’s 2022 position statement finds the benefit-risk ratio favorable for women under 60 or within 10 years of menopause who have bothersome symptoms and no contraindications. In November 2025 the FDA moved to remove boxed warnings about cardiovascular disease, breast cancer and probable dementia from hormone therapy labels, while keeping the endometrial cancer warning for estrogen used without a progestogen.

SAFETY
Risks, side effects and who should avoid it
Not for women with a history of breast or endometrial cancer, unexplained vaginal bleeding, blood clots, stroke, heart disease or active liver disease. Observational data suggest patches and gels carry a lower clotting and stroke risk than tablets. Breast tenderness and spotting can occur early. Absolute risks rise with age and time since menopause, which is why timing matters.
This summary is not a complete list of risks. Read the official prescribing information and discuss your own history with your clinician.
