Hormone Replacement Therapy: Common Myths and What Guidelines Say
Hormone Replacement Therapy: what people commonly get wrong, set against what published UK guidance says.
The risk picture was widely misreported for two decades, and the current position depends heavily on age and time since menopause.
Key takeaways
- Most effective treatment: for vasomotor symptoms such as flushes
- Under 60 or within 10 years of menopause: benefits generally outweigh risks for most
- Most useful single change: Discuss your individual risk rather than relying on headlines.
- Commonest mistake: Oestrogen without progestogen if you have a womb.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What the guidance actually says
The numbers first, since the corrections only mean something against them.
| Measure | Figure |
|---|---|
| Most effective treatment | for vasomotor symptoms such as flushes |
| Under 60 or within 10 years of menopause | benefits generally outweigh risks for most |
| Progestogen | needed alongside oestrogen if you have a womb |
| Transdermal oestrogen | not associated with the clot risk seen with tablets |
| Vaginal oestrogen | acts locally; suitable for many who cannot take systemic HRT |
Where people go wrong
Each of these is popular. None of it matches the guidance.
- Oestrogen without progestogen if you have a womb
- Compounded bioidentical hormones from unregulated sources
- Stopping abruptly rather than discussing a plan
What to do instead
- Discuss your individual risk rather than relying on headlines
- Ask about transdermal routes if clot risk is a concern
- Ask about vaginal oestrogen for genitourinary symptoms specifically
- Review annually rather than continuing or stopping by default
The part that is genuinely uncertain
Guidance changes, and it changes because evidence does. The figures above reflect current UK guidance from the bodies named at the foot of this page; where those bodies revise their position, theirs is the account to follow rather than this one.

When to speak to a doctor
Always report bleeding after the menopause, unexpected bleeding on HRT, bleeding between periods or after sex — these need investigation. Seek urgent help for calf pain or swelling, chest pain, severe breathlessness, sudden severe headache, weakness on one side or vision loss. Report new breast lumps promptly.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
