FDA looks at birth control effectiveness standards

WASHINGTON - Birth control pills could get a makeover.

The Food and Drug Administration plans to ask a panel of experts whether the pills should meet a standard of effectiveness before they're approved for sale.

The FDA says newer pills appear to be less effective at preventing pregnancy than those approved decades ago, probably because manufacturers are using lower doses of the hormones that stop ovulation.

"The very first pills were very high dose and carried risks of blood clots and cardiovascular problems that would be unacceptable to most women," said Amy Allina, program director of the National Women's Health Network. "Today, most birth control pills are very safe for the vast majority of women."

The FDA wants the experts to explain whether the benefit of improved safety outweighs a slightly increased risk of unwanted pregnancies.
