Is hormone therapy safe? The complete safety hub
Hormone therapy is neither the danger a generation was warned about nor a risk-free wellness product. Here is everything we have written about what the evidence actually supports.
Medically reviewed by Sean Arora, MD
For most healthy women under 60, or within 10 years of their final period, the benefits of hormone therapy generally outweigh the risks. That is the position of The Menopause Society and ACOG. It is also not the same as saying hormone therapy is simply safe, or right for everyone, and the honest answer depends on your history.
Most of what women have been told about hormone therapy traces back to a single set of headlines from 2002. Those headlines were not invented, but they were reported in relative rather than absolute terms and drawn from a study population much older than the women who typically seek treatment. Twenty years of reanalysis later, the guidance looks quite different, and yet the fear has outlived the evidence that produced it.
For healthy women younger than 60 or within 10 years of menopause onset, the benefits of hormone therapy generally outweigh the risks for treating bothersome vasomotor symptoms and preventing bone loss.
The pages below work through that history and its practical consequences: what the trial actually measured, why the timing of when you start matters, how the delivery route changes the risk picture, who should not take hormone therapy at all, and how long women stay on it. Read them in any order. Then have the conversation with a clinician, because none of it substitutes for a review of your own history.

For most healthy women under 60 or within 10 years of menopause onset, the benefits generally outweigh the risks, which is the position of The Menopause Society and ACOG. It still carries real risks and is not appropriate for everyone, so a licensed clinician reviews your full personal and family history before prescribing.
