HRT for menopause: the short answer
Hormone replacement therapy, also called menopausal hormone therapy, replaces some of the oestrogen that declines around menopause. It is a prescription treatment, not a single brand or dose. Systemic HRT circulates through the body and is the most effective treatment for hot flashes and night sweats. Local vaginal oestrogen is designed mainly for vaginal and urinary symptoms.
The right decision is personal rather than ideological. Age, time since menopause, symptoms, whether you have a uterus, bleeding, migraine, clotting, breast history, heart and liver health all matter. For many healthy symptomatic women younger than 60 or within 10 years of menopause, the benefit-risk balance can be favourable, but that statement does not replace individual assessment.
Types of HRT and how they differ
Oestrogen may be delivered by tablet, patch, gel or spray. Tablets pass through the liver first; transdermal forms deliver oestrogen through the skin and generally have less effect on clot risk. Vaginal tablets, creams or rings use low doses at the tissue for dryness, pain, urgency and recurrent urinary symptoms.
If you still have a uterus, systemic oestrogen normally needs a progestogen to protect the uterine lining. This may be taken continuously, cyclically or delivered in selected cases through an intrauterine system. After hysterectomy, oestrogen-only therapy is often appropriate. A prescription should identify the symptom target, route, dose and endometrial-protection plan.
Benefits: what HRT can and cannot do
HRT is most effective for vasomotor symptoms such as hot flashes and night sweats. By reducing those symptoms it may improve sleep, concentration and quality of life. Systemic oestrogen reduces bone loss while treatment continues and may be especially important when menopause occurs early. Local vaginal oestrogen can be highly effective for genitourinary symptoms.
HRT is not a weight-loss treatment, a cure for every midlife symptom or a universal preventive medicine. It should not be started solely to prevent heart disease or dementia. Joint pain, mood and brain fog may improve for some women, particularly when driven by sleep and temperature symptoms, but overlapping causes still need attention.
Risks in context
Risk is not one number. Combined oestrogen-progestogen therapy is associated with a small increase in breast-cancer risk that generally rises with duration. Oestrogen-only therapy has a different breast-risk profile. Oral oestrogen can increase venous-clot and stroke risk, while transdermal oestrogen is often preferred when those risks are relevant. Gallbladder effects and bleeding patterns also vary by route and regimen.
Absolute risk depends on baseline health. Two women using the same product can have different starting risks because of age, smoking, obesity, blood pressure, family history, previous cancer or clotting conditions. Ask for benefits and harms in absolute numbers where possible, not only relative percentages. Review should include both the risk of treatment and the cost of leaving severe symptoms untreated.
Who needs specialist advice or an alternative
Systemic HRT usually needs specialist or careful multidisciplinary advice with a history of hormone-sensitive breast or endometrial cancer, unexplained vaginal bleeding, previous blood clot, stroke, heart attack, active liver disease or complex cardiovascular risk. Pregnancy must also be excluded where relevant. This is not a complete contraindication list.
Not using systemic HRT does not mean no treatment. Menopause-specific CBT, selected antidepressants, gabapentin and other licensed or guideline-supported nonhormonal options may help temperature symptoms. Vaginal moisturisers, lubricants and, depending on clinical context, local prescription treatments can address vaginal symptoms. Compounded products are not proven safer than regulated preparations.
Starting, side effects and monitoring
Before starting, clarify the main symptom, uterus status, last period, contraception needs, bleeding history, blood pressure, relevant screening, medicines and personal and family risks. Treatment often begins with an appropriate low dose and is reviewed after roughly three months, then periodically. The goal is the lowest effective dose that meets the agreed outcome, not the lowest dose regardless of benefit.
Early side effects can include breast tenderness, bloating, headache, nausea or spotting. Some settle as the body adjusts, but troublesome or persistent symptoms may require a change in dose, route or progestogen. Unexpected heavy bleeding, bleeding that begins after a period of stability, or bleeding after menopause needs assessment rather than automatic reassurance.
Questions to take to your appointment
Ask: Which symptom are we treating? Do I need systemic or only local therapy? Do I need progestogen? Would a patch or gel suit my risks better than a tablet? What are my absolute risks with and without treatment? What side effects and bleeding should I expect? When will we review benefit, blood pressure and any screening needs?
Bring every prescription, over-the-counter medicine and supplement. Mention migraine with aura, previous clots, breast biopsies or cancer, unexplained bleeding, liver disease, smoking, hypertension and pregnancy possibility. Shared decision-making means receiving clear evidence and having your priorities taken seriously. It does not mean you must arrive already knowing the answer.
Frequently asked questions
What is HRT for menopause?
Hormone replacement therapy supplies oestrogen, with a progestogen when needed, to treat menopause symptoms. It is also called menopausal hormone therapy.
What symptoms does HRT help most?
Systemic HRT is the most effective treatment for hot flashes and night sweats. It can also improve related sleep disruption and protects bone while it is used.
Do I need progesterone with oestrogen?
If you have a uterus, systemic oestrogen normally needs adequate progestogen to protect the uterine lining. After hysterectomy, oestrogen alone is often used.
Does HRT cause breast cancer?
Risk depends on formulation, duration and personal baseline risk. Combined HRT is associated with a small increase in breast-cancer risk; decisions should use absolute risk and individual context.
Is a patch safer than a tablet?
Transdermal oestrogen generally has less effect on clot risk than oral oestrogen and may be preferred when clot or metabolic risk matters. The whole prescription still needs individual review.
How long can I take HRT?
There is no universal stop date. Benefits and risks should be reviewed periodically, and continuation depends on symptoms, health, formulation and preference.
