Birth Control Overview (cont.)
IN THIS ARTICLE
What is RU-486 (mifeprestone)?
A drug called mifepristone (also known as RU-486) can block production of progesterone, a hormone produced by the placenta that is needed for pregnancy to continue, assuming an egg has been fertilized and implanted in the uterus. By taking this drug (and another one called misoprostol)), a pregnancy can be terminated if 49 or fewer days have elapsed since the onset of the last menstrual period.
What new methods and types of hormonal birth control are being studied?
Although development of new birth control methods in the United States has slowed in the past few years, research outside of the United States continues at a rapid pace. Many new birth control designs are being tested to provide a greater variety of methods with fewer side effects, greater safety, and efficacy.
