    EllaOne product information

    EllaOne is a morning after pill which can be taken to prevent pregnancy up to 120 hours (5 days) after unprotected intercourse.

    It contains an active ingredient called ulipristal acetate which modifies the hormone progestogen in our body to help delay the release of egg from the ovary, a process known as ovulation. It is an contraceptive that can help prevent a pregnancy from happening. If you are already pregnant, it will not help to interrupt the pregnancy.

    Note: EllaOne is not 100% effective. Of 100 women who take EllaOne, approximately 2 will become pregnant. However, the correct use of EllaOne can help minimise the chance of being pregnant.

    How to take

    ellaOne is a single dose tablet which is taken as soon as possible and no later than 5 days (120 hours) after unprotected sex. You can take it at any point of your menstrual cycle.

    If vomiting occurs within 3 hours after taking the tablet, take another dose as soon as possible.

    ellaOne should not be taken with another emergency contraceptive pill, Levonelle.

    Note: EllaOne can make your regular hormonal contraceptives temporarily less effective. If you are currently taking hormonal contraception, continue to take it but use an extra contraceptive method eg. condom until your next period. Some medicines can also make EllaOne less effective (see ' cautions' below). If you have taken these medicines recently, your doctor may suggest you another method of emergency contraception.

    Side effects of ellaOne

    As with any medicine, ellaOne can produce side effects, although not everyone gets them. The most common side effects reported for ellaOne are headache, nausea, painful periods, stomach pain, tiredness or dizziness.  It is important that if you experience dizziness that you avoid driving or operating machinery.

    Some symptoms such as breast tenderness or heaviness, stomach pain, nausea and vomiting can be a sign of pregnancy. If you your period is more than 5 days late after taking EllaOne and you experience these symptoms, you should see a GP or have a pregnancy test.

    The full list of side effects can be found on the patient information leaflet attached below.
