Ulipristal Acetate: The Latest in Emergency Contraception.

ABSTRACT

Unintended pregnancy is a global reproductive health problem. Emergency contraception (EC) provides women with a safe means of preventing unwanted pregnancies following unprotected intercourse. Current gold standard emergency contraceptive is levonorgestrel (LNG) given within 72 hours of unprotected intercourse. Ulipristal acetate is a selective progesterone receptor modulator (SPRM) recently approved by US FDA for emergency contraception. It can be used upto five days (120 hours) after an unprotected intercourse and a single dose of 30 mg is effective.
