EllaOne® is an emergency contraceptive and should only be used in an emergency: it should not be used as a regular contraceptive and will not protect you against future incidents of unprotected sex. After using EllaOne®, if you want to have sex, you should use a reliable barrier contraceptive method such as a condom. This is because EllaOne® will not work if you have unprotected sex again.
Be aware that taking EllaOne® may impact the effectiveness of regular hormonal contraceptives like the birth control pill, the injection or the implant. After using EllaOne® , if you wish to start hormonal contraception such as birth control pill in the same cycle, you should do so no sooner than 5 days after taking EllaOne® and you should use a reliable barrier contraceptive method, like condoms, alongside your regular contraception until your next period.
After taking EllaOne®, most women have a normal period at the expected time. Some may have their period later or earlier than normal. If your period is later than seven days or is unusually light or unusually heavy or if you experience symptoms such as abdominal pain, nausea, vomiting o breast pain we advise you take a pregnancy test.
Emergency contraception is not effective in every case and is not a guaranteed method of contraception. If you do become pregnant after taking EllaOne® you should contact your doctor.
