More About RU-486
RU-486 can also function as emergency contraception if administered after intercourse and before ovulation. Unlike other forms of emergency contraception it does not work by blocking implantation but rather by preventing ovulation. Though it can be utilized as emergency contraception it is important to note that RU-486 is distinct from all other forms of EC. No emergency contraceptives, other than RU-486 are authorized for medical abortion.
