Centre for Christian Ethics 120 Herring Rd, Eastwood NSW 2122 OCCASIONAL PAPER 7 - REVISED Should RU486 be available in Australia? "There is no quick fix for pregnancy, no magic pill." – father of 18-year-old Californian woman Holly Patterson who died as a result of taking RU486 in 2003 "These are violently active chemicals and they have violent reactions on the organism … [What is the] situation in which a woman would undergo that kind of assault?" – Australian feminist Dr Germaine Greer, addressing gynaecologists and obstetricians in 2002 "A drug which ends a new human life and endangers a woman's health is never a ‘safe and effective' solution." – Dr Brigid Vout, Life Office, Catholic Diocese of Sydney What is RU486? RU486 is not the same as the "morning after" pill (Postinor-2). RU486 is the generic term for mifepristone, an artificial steroid that blocks progesterone, a vital nutrient hormone. It causes the nutrient lining of the mother's uterus to disintegrate, and the embryo withers and dies. A second drug, misoprostol, a prostaglandin developed to treat ulcers, is used 48 hours later to induce uterine contractions that detach and expel the embryo and uterine contents. More than one million women worldwide have used RU486 to end their pregnancy. RU486 is effective from the fifth to the seventh week following the last menstrual period, with decreasing effectiveness up to the ninth week. Used alone, RU486 has an abortion rate of 60-80 per cent. Used with misoprostol, this rises to 95 per cent. Mifepristone is also used to treat certain rare forms of cancer, and may have other therapeutic applications. Mifepristone was developed by Roussel-Uclaf, a French pharmaceutical company. Possible side effects and complications A common side-effect is severe pain similar to that of miscarriage, with over half of women needing specific pain medication and one-third needing narcotics. Other side-effects may include nausea and dizziness, syncope (brief loss of consciousness), serious bacterial infection, sepsis, prolonged bleeding (averaging from 9 to 30 days) and death. Some women who experienced severe bleeding as a result of taking the drug required blood transfusions. Women lacking ready access to ultrasound and blood transfusion, such as those in remote communities and developing countries, are more likely to die. The drug does not affect ectopic
