  • 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.

ellaOne® is contra-indicated for women who:

Are hypersensitive to the active substance or to any of the excipients1

Always refer to the ellaOne® Summary of Product Characteristics if you are in any doubt.

Situations where ellaOne® is not recommended

• Severe asthma treated by oral glucocorticoids1

• Severe hepatic impairment1

• For women taking CYP3A4 inducers1

• For women with long-term use of ritonavir1

• Concomitant use of EC containing levonorgestrel1

• Breastfeeding is not recommended for one week after ellaOne® intake1


Pregnancy registry

ellaOne® ( 30mg ulipristal acetate) is an emergency contraceptive pill (ECP), now available in pharmacy without a prescription in Ireland. 

The OTC availability of emergency contraception pills is critical to increase access and minimise any delay in taking them. This is especially significant given that emergency contraception pills are more effective the sooner they are taken after unprotected intercourse.

The advice of pharmacy staff and emergency contraceptive efficacy are the two most important factors in the choice of emergency contraceptive pill.1

This website has been developed to help you learn more about ellaOne®. This website is for healthcare professionals only. It is aimed at community pharmacists in Ireland, pharmacy assistants and anyone in the pharmacy team who may dispense emergency contraception.

It will help you make responsible, confident recommendations and give appropriate advice to women requesting emergency contraception in your pharmacy.


It will help you give appropriate counselling on ellaOne® as well as subsequent contraceptive care, to support the best health outcomes.
