The one death was unrelated to either abortion or use of the pill, the Food and Drug Administration said. The second woman showed symptoms of infection. Four other women have died of a rare but deadly infection after undergoing pill-triggered abortions.
In those four deaths, all involving Californians, the women tested positive for Clostridium sordellii, a common but rarely fatal bacterium.
The agency has warned doctors to watch for infection by the bug. However, the drug, also called Mifeprex or mifepristone, has not been proved to be the cause in any of those cases, the FDA has said, reports AP.
According to , Reuters, RU-486, also known as Mifeprex or mifepristone, is approved for terminating a pregnancy of 49 days or less. Another drug, misoprostol, is given two days later to complete the abortion.
"Of the two most recent deaths ... one has been determined to be unrelated to an abortion or to the use of Mifeprex and misoprostol and the other, with symptoms of infection, continues to be under investigation," the FDA said in a statement.O.Ch.
