Ulipristal acetate, sold under the brand name Ella among others, is a medication used for emergency birth control and uterine fibroids. As emergency birth control it should be used within 120 hours of sex. For fibroids it may be taken for up to six months. It is taken by mouth.

Common side effects include headache, nausea, feeling tired, and abdominal pain. It should not be used in people who are already pregnant. It is in the selective progesterone receptor modulator (SPRM) class of medications. It works by preventing the effects of progesterone thus stopping ovulation.

Ulipristal acetate was approved for medical use in the United States in 2010. It is on the World Health Organization's List of Essential Medicines. In the United Kingdom it costs the NHS about 17 pounds per course of emergency birth control of 2015. To improve access, some recommend all who can get pregnant be given a prescription for use if needed.
