MEDICATION SAFETY

Ulipristal acetate safety summary

  • INN
  • ulipristal acetate
  • selective progesterone-receptor modulator
  • 30 mg single oral tablet
  • brand: ellaOne

Ulipristal acetate is an emergency-contraception pill that can delay ovulation even when it is about to happen, and stays effective for up to 120 hours (5 days) after unprotected sex. As with all emergency contraception, sooner is still better.

Emergency contraception within 120 hours (5 days) of unprotected sex or contraceptive failure.

  • One 30 mg tablet, taken as soon as possible, with or without food.
  • Can be taken at any point in the menstrual cycle.
  • If you vomit within 3 hours of taking it, take another tablet.
  • It is a backup, not a regular contraceptive, and does not protect for the rest of the cycle.

Rare, but do not wait these out.

  • Sudden, severe lower abdominal pain — especially with a positive pregnancy test after use — can signal an ectopic pregnancy and needs urgent assessment.
  • Severe allergic reaction — rash, swelling of the face or throat, difficulty breathing.

WHEN TO CALL THE DOCTOR
