Changes in Emergency Contraceptive Effectiveness Associated with Co-administration of Other Products.

If a person wishes to start or resume hormonal contraception after the intake of Ella, they should do so no sooner than 5 days after taking Ella. Additionally, a rapid return of fertility is likely, following treatment with Ella, so a reliable barrier method should be used until the next menstrual period.

  • barbiturates

  • griseofulvin
  • oxcarbazepine
