Study shows hormone pills don’t shorten the lives of older women

CHICAGO Taking hormone pills for several years after menopause didn't shorten older women’s lifespans, according to the longest follow-up yet of landmark research that transformed thinking on risks and benefits of a once popular treatment.

That research was halted early when unexpected harms were found from using replacement hormones — estrogen alone or with progestin — versus dummy pills for five to seven years. More breast cancer, heart attacks and strokes occurred in women on combined pills, and those on estrogen pills had more strokes.

But about 18 years of follow-up show that despite those risks, women had similar rates of deaths from heart disease, breast cancer and all other causes as those who took dummy pills.

The new results are reassuring and support current advice: Hormones may be appropriate for some women when used short-term to relieve hot flashes and other bothersome menopause symptoms, said Dr. JoAnn Manson, preventive medicine chief at Boston’s Brigham and Women’s Hospital and lead author of the followup report.

“It’s the ultimate bottom line,” said Manson, who was also part of the original research. Women want to know “is this medication going to kill me” and the answer appears to be no, she said.

Results were published Tuesday in the Journal of the American Medical Association.
