The Food and Drug Administration is looking into stricter standards for the birth control pill after finding that pills approved decades ago are more effective than those being marketed today.

The FDA asked a group of 14 experts to decide whether new standards should be implemented. The group will reconvene on Wednesday.

Newer oral contraceptives have been found to be up to twice as faulty as pills produced years ago. This is because producers began using lower doses of hormones to make the product safe for the majority of women. Consequently, the lower dose does not always stop ovulation.

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

The Pill is one of the most commonly used methods of birth control. According to research group Guttmacher Institute, more than 60 percent of women ages 15 to 44 use contraceptives and more than 11 million of them use the pill as their primary form.
