What is ellaOne

ellaOne is a method of emergency contraception whose purpose is to prevent pregnancy after unprotected sex has taken place or regular birth control has failed. Also known as the ‘morning after pill’, ellaOne is effective for up to five days following an episode of unsafe sex and can stop pregnancy even if you are due to ovulate. As such ellaOne has been shown to prevent more pregnancies than any other form of emergency contraceptive in the UK.

EllaOne should be taken as soon as possible after unprotected sex to maximise its effectiveness. However, ellaOne has a longer window of use than Levonelle. EllaOne has to be taken within five days (120 hours) of unprotected sex – allowing 48 hours extra than Levonelle.

EllaOne is taken as a single tablet. Whereas the effectiveness of Levonelle starts to decrease after 12 hours, EllaOne is thought to remain up to 95% effective throughout the five day window.

How effective is ellaOne?

ellaOne is the only morning-after pill which has been seen to remain 95% effective at stopping an unwanted pregnancy for up to five days after unprotected sex, however, as with any medication of this type, it is recommended that it is taken as soon as possible.

Why choose ellaOne?

Unlike the emergency contraception tablet Levonelle which loses its effectiveness after 72 hours following unprotected sexual intercourse, ellaOne remains effective for up to five days or 120 hours.

Not only does taking this single-dose tablet right away provide less time for the sperm to fertilise the egg and cause an unwanted pregnancy, it also stops you worrying because, once taken, you know the chances of pregnancy are extremely low.

How should I take ellaOne?

Treatment is a single tablet to be ingested orally. It should be taken as soon as possible after intercourse with a glass of water before, during or after a meal.

If you think there may be a chance you will have unprotected sex in the future or your contraception may fail again, then you can buy more than one tablet to keep at home for peace of mind.

How does ellaOne work?

In a regular menstrual cycle, an egg is released, ready to be fertilised by awaiting sperm. Progesterone produced at this time naturally stops any further eggs from being released. By delaying the release of the egg, the sperm are no longer alive and able to cause a pregnancy by fertilising the egg.

The two most commonly used pills are Levonelle and ellaOne, and they both work in slightly different ways. ellaOne works for five days after intercourse, and its active ingredient, ulipristal acetate, stops the progesterone in your body from working as it usually would and, in turn, delays the eggs’ release from the ovary.

What are the side effects of ellaOne?

Taking ellaOne has not been known to cause any serious or long-term health concerns or fertility issues; however, as with any medication, there can be potential side effects. The most common symptoms found in patients after taking ellaOne is gastrointestinal disturbances, for example, nausea, vomiting and diarrhoea.

Other side effects include:

  • headaches
  • dizziness
  • tiredness
  • mood changes
  • swelling of the breasts

Depending on how your body reacts to the medication, the period following taking ellaOne may be delayed or early and either lighter or heavier than usual. If there is no subsequent period and /or it is noticeably different to your regular periods, then there is a potential that pregnancy has still occurred, and as such, you should consult your GP for advice.

If there is any chance that you may already be pregnant, then it is recommended not to take ellaOne as there could be harmful effects on the development of the foetus.

If you experience any severe symptoms after taking this medication, it is important to seek medical advice as soon as possible.
