Federal regulators are adding a new warning to an abortion pill, saying that the drug may lead to serious bacterial infection.
This comes more than a year after an 18-year-old California girl died after taking RU-486 to end an unplanned pregnancy.
In the United States, RU-486 has been approved for use in a drug called Mifeprex.
The drug already carries a black box warning, which is the highest caution issued by the Food and Drug Administration. But now that warning will expand to add information about potentially deadly infections and bleeding that can follow any abortion. Those infections can happen with almost no symptoms or warning.
Anti-abortion activists have campaigned against RU-486 since it was approved. The drug can be used only during the first six weeks of pregnancy.
