Ulipristal Acetate - Dosage and How to Use

How should Ulipristal Acetate be used?

  • ​You may take this medication with or without food.
  • You may take the medication at any time during the menstrual cycle.
  • Take one tablet (30mg) as soon as possible within 120 hours (5 days) of intercourse.
  • Do not repeat the medication during the same menstrual cycle due to limited information.
  • If you vomit within 3 hours after taking the medicine, take another tablet as a replacement. Consult a doctor to get an additional dose of the medicine.

You may still get pregnant if there is sexual intercourse after taking the pill. Use a condom or any other type of birth control method if you have sexual intercourse after taking the emergency contraceptive pill.

What should I do if I miss a dose?

​The tablet works best the sooner you take it after having unprotected sex. It can only prevent you from becoming pregnant, if you take it within 5 days of unprotected sex. Please contact your healthcare professional if it is more than 5 days of unprotected sex.

What should I do if I overdose?

Ulipristal Acetate - Additional Information

​When can I start my regular hormonal contraception after taking this medication?

You can start/restart hormonal contraception e.g. birth control pills 5 days after taking Ella®. You must also use a barrier method (for example; condoms, diaphragms and spermicides) until your next menstrual period, or not have sexual intercourse.

Using a hormonal birth control method and taking Ella® at the same time can reduce the effectiveness of both medications.
