Study: Long-lasting forms of birth control more effective

A new study reports that long-lasting forms of birth control, such as implants and intrauterine devices, are better than birth control pills and patches.

The study is published in the New England Journal of Medicine.

Researchers found that long-acting contraception is about 20 times more effective at preventing pregnancy than pills, patches or vaginal rings.

The study involved about 7,500 women in a project promoting long-acting birth control to reduce unintended pregnancies.

"IUDs and implants are more effective because women can forget about them after clinicians put the devices in place," said Dr. Jeffrey Peipert, a professor of obstetrics and gynecology at Washington University.

Failure rates for such methods are less than 1 percent, but require an office procedure and cost more.
