Ingest the first dose of a medical abortion pill at the doctor's office, and then take the second dosage at home within 48 hours of the first one, according to WebMD. A person may use this method to abort a fetus up to nine weeks into a pregnancy.
Ingest the first dose of medication, mifepristone, by mouth at the doctor's office, notes WebMD. This medication separates the endometrium from the placenta, softens the cervix and increases uterine contractions. Mifepristone prepares the uterus to expel its contents.
Take the second medicine, misoprostol, by mouth or insert them vaginally, says WebMD. This could happen as soon as six hours after taking mifepristone. Some forms of misoprostol can be dissolved between the gums and cheek. This medication causes contractions within the uterus in order to empty that part of the body. Within the first seven weeks of pregnancy, these medications work 92 percent of the time; a follow-up appointment checks to ensure the success of the medical abortion.
These two medications are 95 to 97 percent effective when taken within two weeks, according to the Feminist Women's Health Center. Mifepristone blocks progesterone needed to maintain a pregnancy, while misoprostol usually terminates the pregnancy within six to eight hours of use. Side effects of taking misoprostol include bleeding and cramping.
Four different methods are used during medical termination of pregnancy in developed countries, notes the World Health Organization. The most common MTP method involves mifepristone followed by prostaglandin 48 hours later.
