What is EllaOne?

EllaOne is one of the most popular choices for morning after pills. It contains the active ingredient of ulipristal acetate, which delays the release of an egg from the ovaries. It should be taken as soon after unprotected sex as possible.

How does EllaOne work?

EllaOne works through the active ingredient of ulipristal acetate – a chemical that modifies the natural female sex hormones to delay or prevent the release of an egg from the ovaries, decreasing the chances of the egg coming into contact with sperm and fertilising. This effect continues for a five-day period, which is usually when all of the sperm will have died and it is safe for the egg to be released.

How reliable is EllaOne?

EllaOne has a reputation for being one of the most reliable morning after pills. It is thought to remain approximately 98% effective for up to five days after being taken.

How should EllaOne be taken?

EllaOne should be taken as soon as possible after unprotected sex takes place, and the effects last for five days. After the five-day window has passed, it is not known if EllaOne is still effective in any capacity, so it must be taken before this window disappears. The pill should be swallowed whole with water.

Is EllaOne suitable for me?

EllaOne is suitable for women only who are wishing to prevent pregnancy after unprotected sex. It is only suitable for use once during the current menstrual cycle, and it is important to note that it may cause some disruption to other contraceptive methods, such as the combined pill. If you have already ovulated or are already pregnant, EllaOne is not appropriate for you. Do not take EllaOne if you are allergic to any of its ingredients.
