What ellaOne® is not

NOT a regular contraceptive method

You should not use ellaOne® as a regular method of contraception. The emergency contraceptive pill is a backup method for preventing pregnancy and should only be used occasionally.

NOT a contraceptive for future intercourse

If you have unprotected sex again after taking ellaOne®, it will not stop you from becoming pregnant. You should use a barrier method, such as condoms, every time you have sex until your next period. If you are currently taking the contraceptive pill, continue to use it as usual, starting the day after taking ellaOne®. Be sure to also use condoms every time you have sex until your next period.

NOT interrupt an existing pregnancy

ellaOne® works by delaying egg release. If you are pregnant it is too late for emergency contraception because it works to prevent the start of a pregnancy. So, you should not take ellaOne® if you are already pregnant.

ellaOne® does not affect your fertility

If you want to have sex after using ellaOne®, use a barrier method of contraception until your next period. This is because your fertility can come back very quickly.

What is ellaOne®?

  • ellaOne® is a morning after pill that can prevent a pregnancy after unprotected sex, or if your contraceptive method has failed 1
  • ellaOne® is effective when it matters most because it can prevent pregnancy even when you are about to ovulate – which is when your risk of getting pregnant is at its greatest
  • ellaOne® works by delaying ovulation (egg release). By the time an egg is released the sperm inside you are no longer capable of making you pregnant
  • Each tablet of ellaOne® contains 30 mg ulipristal acetate
  • ellaOne® is easy to take  – it is a single tablet to be taken as soon as possible after unprotected sex
  • ellaOne® should be taken as soon as possible, but no later than 5 days (120 hours) after unprotected sex or contraceptive failure
  • ellaOne® is suitable for women of reproductive age
  • ellaOne® can be taken any time during your cycle
