Home - EllaONE


EllaOne is the most effective emergency contraceptive product available on the market today. It can prevent unwanted pregnancy and can be taken up to 120 hours (5 days) after unprotected sex. It contains Ulipristal Acetate which works by acting on the body’s receptors for the female sex hormone progesterone.  

EllaOne prevents or delays ovulation so that conception cannot take place. In this time the sperm present in the womans body die and therefore cannot fertilise the egg when it is released. It is estimated that only 2% of ladies who take EllaOne will become pregnant after taking it within 120 hours.  The pill is more effective the earlier it is taken during the 5 day window.

After taking EllaOne oral contraceptives such as the pill may not be as effective so you will need to use a barrier method for up to two weeks to prevent pregnancy.

EllaOne is the most effective emergency contraceptive producton the market at preventing pregnancy after unprotected sex or if your contraceptive method has failed. Unlike the older emergency contraceptives, EllaONE can be used up to 120 hours (5 days) after unprotected sexual intercourse although it is more effective if used sooner..

You should take ellaOne as soon as possible after sex, and within a maximum of 5 days (120 hours). Sperm can survive up to 5 days in your body after intercourse.

EllaOne is suitable for any woman of childbearing age, including adolescents. You can take EllaOne at any time in the menstrual cycle.ellaOne does not work if you are already pregnant. Although, if it is taken it will not interfere with the pregnancy.

If your menstrual period is late, there is a possibility that you may be pregnant. When your period is late or when you have symptoms of pregnancy (heavy breasts, morning sickness) you should consult a doctor or other healthcare professional before taking EllaOne.  EllaOne is a contraceptive used to prevent a pregnancy from starting. If you are already pregnant, it will not interrupt an existing pregnancy.

If you have unprotected sex after taking EllaOne, it will not stop you from becoming pregnant. Unprotected sex at any time during your cycle can lead to pregnancy. EllaOne is not to be used for regular contraception If you do not have a regular method of contraception, talk to your doctor or healthcare professional to choose one that is suitable for you.

How EllaOne works

EllaOne contains the active ulipristal acetate which acts by modifying the activity of the natural hormone progesterone which is necessary for ovulation to occur. As a result, ellaOne works by postponing ovulation. Emergency contraception is not effective in every case. Of 100 women who take EllaOne approximately 2 will become pregnant.

Emergency contraception does not protect against sexually transmitted infections Only condoms can protect you from sexually transmitted infections. Ask a healthcare professional for advice if you are worried about this.


How to take the EllaOne tablet

• Take one tablet by mouth as soon as possible and no later than 5 days (120 hours) after unprotected sex or contraceptive failure. Take the tablet without delay.

• You can take EllaOne at any time in your cycle.

• You can take EllaOne at any time of the day either before, during or after a meal.

If you vomit (be sick, throw up) within 3 hours of taking the tablet, take another tablet as soon as possible.

If you have unprotected sex after taking EllaOne, it will not stop you from becoming pregnant.

After you take EllaOne and until your next period comes, you should use condoms every time you have sex.

After taking EllaOne, it is normal for your next period to be a few days late. However, if your period is more than 7 days late; if it is unusually light or unusually heavy; or if you experience symptoms such as abdominal (stomach) pain, breast tenderness, vomiting or nausea, you may be pregnant. You should do a pregnancy test right away. If you are pregnant, it is important that you see your doctor.
