Plainly Her Answers

Is HRT safe?

The short answer

For most healthy women starting within ten years of their final period and under sixty, the benefits generally outweigh the risks. In November 2025 the FDA removed the broad boxed warnings on cardiovascular risk, breast cancer and dementia. It remains an individual decision made with a clinician.

The fuller picture

  • The 2025 change removed the boxed warning from systemic products and from low-dose vaginal oestrogen. The endometrial cancer warning on oestrogen-alone products remained, which is why women with a uterus are prescribed a progestogen alongside it.
  • A labelling change is a correction to how the 2002 findings were being communicated. It is not a declaration that hormone therapy is right for everybody, and no regulator said that.
  • Timing is the single biggest variable. The risk picture for a fifty-two year old starting two years after her final period is materially different from that of a sixty-five year old starting fifteen years after.
  • Route matters too. Transdermal oestrogen, patches and gels, is not associated with the clot risk seen with oral preparations, which is why it is often preferred where there is any vascular concern.

This is the question with the most history attached to it, so it is worth being precise about what changed and when.

In 2002 the Women’s Health Initiative reported early results that were communicated, both by the investigators and by the press, as showing that hormone therapy increased breast cancer and cardiovascular risk. Prescribing collapsed worldwide within eighteen months. A generation of women went through menopause without treatment that would have helped them, and a generation of doctors trained without learning to prescribe it.

Subsequent reanalysis showed the original communication had flattened out crucial distinctions: the average participant was sixty-three, well over a decade past her final period, and the findings in women in their fifties looked substantially different. In November 2025 the FDA removed the broad boxed warnings from menopausal hormone therapy labelling, including from low-dose vaginal preparations where the systemic absorption is negligible.

What that does and does not mean for you

It means the default framing has changed. The conversation now starts from “is this appropriate for you” rather than from a black-box warning that ended it before it began.

It does not mean the answer is yes for everyone. A personal history of breast cancer, of blood clots, or of liver disease all change the calculation, sometimes decisively. What it means is that those are the questions, and that a blanket refusal to discuss it is no longer defensible.

What this page cannot do

It cannot tell you whether to take it. Nothing that does not know your history, your blood pressure, your family history and what your symptoms are actually costing you can do that honestly, and any website that offers to is selling you something.

What to do next

  1. Write down your symptoms, their frequency, and what they are stopping you doing. That is the information a prescribing decision is actually made from.
  2. Know your own history before the appointment: clots, breast cancer in you or a first-degree relative, migraine with aura, blood pressure, liver disease.
  3. Ask specifically about route and dose rather than about hormone therapy as a single yes or no. They are different questions with different answers.

Speak to someone rather than reading on if

  • You have any bleeding after twelve months without a period, which is always investigated before anything else is considered
  • You have a personal history of breast cancer, a blood clot, or liver disease, where the decision needs a specialist
