Medical Abortion
Most abortions in Australia are performed by a surgical procedure that removes the pregnancy from the uterus. It is also possible to cause an abortion by using two medication to cause the pregnancy to miscarry. This procedure is a medical abortion.
An early medical abortion is suitable for pregnancies up to 63 days after the start of the last menstrual period..
How it works.
A tablet is used to block the action of progesterone, a hormone essential for a pregnancy.This changes the lining of the uterus, causing the pregnancy to detach. It opens the cervix and increases the sensitivity of the uterus to a second medication that is given.
Administered approximately 48 hours
after the first medication, the second medication causes the uterus to
contract, assisting in the removal of
pregnancy tissue.
Possible side effects
These medications may cause cramping pain and bleeding, usually within one to six hours of using the tablets. Pain can range from mild period-like pain to severe pain. For most women, the pain can be readily managed with pain relievers.
Bleeding can vary from light spotting to a very heavy flow, with blood clots and pregnancy tissue present. The duration of bleeding can also vary - most women will experience spotting for up to two weeks after the medication, however in some cases spotting may last for six to seven weeks.
Headaches, nausea and vomiting may occur, along with flushes or chills.
Continuing pregnancy: Minimal bleeding and continuing pregnancy symptoms can mean the pregnancy is still present. This occurs in about 1% of medical abortions. Surgical termination will be arranged if needed.
Continuing pain and bleeding: For approximately 2% of women having a medical abortion, the tissue will not be completely expelled from the uterus and pain and bleeding will persist. A surgical procedure may be needed to remove the tissue.
Future fertility: Medical abortion does not reduce the chance of becoming pregnant again. Women can become fertile as early as two weeks after an abortion, and need to consider contraception as soon as the current pregnancy is over.
Follow-up care and support
An ultrasound and blood test are used to ensure the abortion is complete. Twenty four hour phone support is available for women undertaking a medical abortion.
