This drug was approved in 8/2010 by FDA to be used to prevent or abort a pregnancy. The generic name is ulipristal acetate, and is a first cousin to RU 486. ELLA is typically used up to 5 days after intercourse. It works by either preventing ovulation (egg release) or by blocking progesterone which is necessary to maintain a pregnancy (keeps fertilized egg from implanting in the uterine wall causing an abortion-like action.)

Patients should seek medical attention if they experience severe lower abdominal pain 3 to 5 weeks after taking ella, in order to be evaluated for an ectopic pregnancy.
Possible side effects/risks are headache, nausea, abdominal pain, fatigue, dizziness.

Since this is a new drug, you may report side effects to FDA at 1-800-FDA-1088. 31
