Hormone therapy, without the fog machine
The HRT Guide: What It Does, Who It Helps, Risks, Benefits and the Shit Nobody Explains Properly
HRT has spent decades being treated like either a miracle potion or a radioactive casserole. It is neither. Here is what menopausal hormone therapy actually does, who may benefit, what the risks really mean, and why your treatment plan should involve more than somebody muttering ‘breast cancer’ and backing slowly out of the room.

The Basic Facts
HRT and MHT are two names for the same treatment family
Menopausal hormone therapy, or MHT, is the current Australian term for what many people still call hormone replacement therapy or HRT. It uses prescribed hormones, usually oestrogen with or without a progestogen, to treat symptoms linked to the menopause transition.
There is no single product called ‘HRT’. Oestrogen can be delivered through tablets, patches, gels, sprays or local vaginal products. Progestogens come in several forms. The route, dose and combination matter because benefits, side effects and risks are not identical across every option.
The Treatment Desk
MHT is the most effective treatment for hot flushes and night sweats
Current Australian guidance describes MHT as a safe and effective treatment for many healthy people with menopause-related symptoms. It is particularly effective for hot flushes and night sweats. It may also help sleep problems or mood changes when those are tied to menopause symptoms, and it helps prevent bone loss while it is being used.
Symptoms and health effects worth discussing
- Hot flushes and night sweats
- Sleep disrupted by vasomotor symptoms
- Vaginal dryness, irritation or painful sex
- Some urinary symptoms linked to genitourinary syndrome of menopause
- Bone loss and osteoporosis risk
- Quality-of-life effects caused by troublesome menopause symptoms
The Risk-Benefit Briefing
For many symptomatic women, the benefits outweigh the risks
The Australasian Menopause Society states that, for the majority of symptomatic women, the benefits of MHT outweigh the risks. Treatment decisions should still be individual. The conversation changes with age, symptom severity, time since menopause, personal and family history, smoking, blood pressure, migraine, clot risk and previous cancer.
MHT is commonly considered particularly favourably for healthy symptomatic women who are younger than 60 or within about 10 years of menopause. That does not create a magical birthday cliff. It means the balance of benefits and risks changes as baseline health risks change with age and time.
Anatomy Has Entered The Meeting
Whether you have a uterus changes the prescription
If you have had a total hysterectomy, oestrogen-only MHT may be appropriate. If you still have a uterus, systemic oestrogen is usually paired with a progestogen. The progestogen protects the uterine lining from the increased risk of endometrial cancer caused by unopposed systemic oestrogen.
The prescription may involve
- Oestrogen-only MHT after total hysterectomy
- Combined oestrogen and progestogen when a uterus is present
- Cyclic progestogen in some people who are still perimenopausal
- Continuous combined therapy in other circumstances
- A suitable hormonal IUD providing the progestogen component for some patients
The Delivery Department
The route matters, especially when clot risk matters
Oral and transdermal oestrogen do not behave identically. Tablets pass through the liver before reaching the wider circulation. Patches and gels deliver oestrogen through the skin. This difference matters when assessing venous thromboembolism risk.
Reasons a clinician may discuss transdermal oestrogen
- A higher baseline risk of blood clots
- Migraine or other factors affecting route choice
- A preference to avoid tablets
- Side effects with another formulation
- A need to tailor treatment while preserving symptom control
The Headline Everyone Remembers
Breast cancer risk is real, but ‘HRT causes breast cancer’ is too crude to be useful
Breast cancer risk depends on the type and duration of systemic MHT, along with a person’s existing baseline risk. Combined oestrogen-progestogen therapy is associated with a different breast cancer risk profile from oestrogen-only therapy. The absolute increase for an individual may be small, but it should be discussed clearly rather than hidden behind either panic or cheerleading.
NICE’s current menopause guidance advises discussing how breast cancer risk varies with the type and duration of HRT. The Australasian Menopause Society similarly recommends putting the risk into individual context and balancing it against symptom burden and other benefits.
The Local News Desk
Low-dose vaginal oestrogen is not the same exposure as systemic MHT
Vaginal oestrogen is used locally for symptoms such as vaginal dryness, burning, discomfort and some urinary symptoms. It produces much lower systemic exposure than standard systemic MHT and is treated differently in guidance.
Local treatment may be discussed for
- Vaginal dryness or burning
- Pain or discomfort during sex
- Vaginal irritation
- Some urinary urgency or recurrent urinary symptoms linked to menopause
- Symptoms that continue despite systemic MHT
The Follow-Up File
Starting MHT should come with a review plan, not a prescription disappearing into the mist
Australian Government guidance says mild side effects can occur when starting MHT and a follow-up is commonly recommended after about 6 to 12 weeks. NICE recommends using the lowest effective dose and reviewing treatment after starting.
At review, discuss
- Which symptoms improved and which did not
- Breast tenderness, nausea, bloating, headaches or other side effects
- Any vaginal bleeding
- Whether the dose or route needs adjustment
- Blood pressure and relevant health changes
- Whether the treatment still matches your priorities
The Complicated Cases Desk
Some histories change the conversation. They do not justify a five-second dismissal
MHT may be unsuitable, require specialist advice or need a different formulation when certain conditions are present. Australian Government guidance highlights histories such as breast or uterine cancer, unexplained vaginal bleeding, certain heart conditions and increased blood-clot risk.
Flag these before prescribing
- Previous breast or endometrial cancer
- Unexplained vaginal bleeding
- Previous blood clot or significant clot risk
- Stroke, heart disease or major cardiovascular risk factors
- Liver disease
- Migraine patterns and other relevant neurological history
- Current medicines that may affect treatment choice
The Marketing Department Has Been Detained
‘Bioidentical’ does not automatically mean safer, and compounded products are not the premium upgrade
Many regulated prescription MHT products already contain hormones that are chemically identical to hormones produced by the body. Compounded ‘bioidentical’ hormones are custom-made products marketed as more natural or personalised. Major Australian guidance does not recommend them.
The Actual Point Of The Meeting
The right question is not ‘Is HRT good or bad?’
The useful question is whether a specific treatment offers more benefit than risk for you, at this point in your life, for the symptoms and health priorities you actually have. Shared decision-making is supposed to be a conversation, not a doctor announcing a verdict from Mount Clipboard.
Your decision checklist
- 01
Name the symptoms you most want treated.
- 02
Ask which MHT options fit your anatomy and medical history.
- 03
Compare routes and formulations, not just the word ‘HRT’.
- 04
Ask for risks in absolute terms where possible.
- 05
Agree on what improvement should look like.
- 06
Set a review date and a plan for side effects or bleeding.
- 07
Revisit the decision when your symptoms, health or preferences change.
