Is hormone therapy (HRT) making a comeback?

A few years ago, the use of hormone replacement therapy (HRT) looked like a medical mess. For decades, women were told that HRT -- usually a combination of estrogen and progestin -- was good for them during and after menopause. Then the 2002 results of the Women's Health Initiative study seemed to show just the opposite: hormone replacement therapy actually had life-threatening risks such as heart attacks, strokes, and cancer.

"Women felt betrayed," says Isaac Schiff, MD, chief of obstetrics and gynecology at Massachusetts General Hospital in Boston. "They were calling their doctors, saying, 'How could you put me on this drug which causes heart attacks, strokes, and cancer?'"

Understanding Menopause -- Symptoms

Almost overnight, standard medical practice changed. Doctors stopped prescribing hormone replacement therapy and 65% of women on HRT quit, according to Schiff.

But some experts say hormone replacement therapy may be coming back. All along HRT remained an important treatment for menopause symptoms like hot flashes. And now, a number of recent studies show that hormone replacement therapy may have protective benefits for women who are early in menopause.

"I think we swung too positive on hormone therapy in the past and then we went too negative," says Schiff, who is also chair of the American College of Obstetricians and Gynecologists Task Force on Hormone Therapy. "Now we're trying to find a balance in between."

"We're definitely in a gray zone of uncertainty about hormone therapy," says Jacques Rossouw, MD, project officer for the federal Women's Health Initiative (WHI). "But when you're uncertain, you have to err on the side of safety."
