  • If there is any reason to believe that the woman may already have an established pregnancy, she should be referred to a doctor.1

ellaOne® is not intended for use during pregnancy and should not be taken by any woman suspected or known to be pregnant.1

However, ellaOne® does not interrupt an existing pregnancy.1

Women may not understand when pregnancy begins. They may believe they are pregnant from the moment of unprotected sex, so asking “Could you be pregnant?” is unhelpful.

More specific questions e.g. “Is your menstrual period due or late?” will be more helpful.

  • ellaOne® does not prevent pregnancy in every case.
  • ellaOne® is for occasional use only. It should in no instance replace a regular contraceptive method. In any case, women should be advised to adopt a regular method of contraception.
  • CYP3A4 inducers (e.g. rifampicin, phenytoin, phenobarbital, carbamazepine, efavirenz, fosphenytoin, nevirapine, oxcarbazepine, primidone, rifabutin, St John’s wort) may result in a decreased efficacy.
  • Absorption may be altered by products that raise gastric pH and the clinical relevance is not known.
  • May reduce action of combined hormonal contraceptives and progestogen-only contraception.
  • Use in women with severe asthma treated by oral glucocorticoid is not recommended.
