ellaOne

ellaOne is a revolutionary new emergency contraceptive pill that can prevent unwanted pregnancy up to five days after unprotected sex or the failure of other contraceptives. This is two days more than the standard "morning-after pill".

In two separate clinical trials, ellaOne was more effective than the widely used ‘morning-after’ contraceptive pill, with less than 2% of the women studied becoming pregnant.

The pregnancy rate for the most commonly used contraception (the contraceptive pill or condoms for example) can be more than 10% per year. So even if you are really careful, there’s still a chance that something could go wrong.

How does ellaOne work?

ellaOne acts by modifying the activity of the natural hormone progesterone. ellaOne works by using a synthetic version of the female hormone progesterone to trick your body into delaying your ovaries from releasing an egg, preventing pregnancy.

In the event that an egg has already been released, ellaOne also works by increasing thickness of the mucus at the cervix and makes the womb lining thinner so an egg can't attach to it. This additional effect reduces the chances of sperm entering the womb and also reduces the chances of pregnancy as an egg won't be able to grow in a thinner womb lining.

ellaOne is not effective in every case. 2 in 100 women receiving ellaOne up to 5 days after unprotected sex will become pregnant.

Instructions

ellaOne should be taken as soon as possible, and no longer than five days after unprotected sex or after other methods of contraception have failed. It can be taken before, during or after a meal. Should you vomit within three hours of taking ellaOne, you should take another dose.

After using ellaOne, if you want to have sex, you should use a reliable barrier contraceptive method such as condom. This is because ellaOne will not work if you have unprotected sex again.

Emergency contraception is a backup method for preventing pregnancy and should only be used occasionally. Only limited information is available concerning the safety and efficacy of repeated use of ellaOne; therefore, you are advised not to use ellaOne more than once in the same menstrual cycle.
