What is Levonelle?

Levonelle One Step is the most effective morning after pill*. If you have had unprotected sex, taking ellaOne^® can prevent unplanned pregnancy. ellaOne^® can be effective for up to 3 days (72 hours) after unprotected sex has taken place, but like all morning after pills it is more effective the sooner you take it. Levonelle One Step is intended for use in the case of emergency it is not meant to be a replacement for a regular method of contraception.

How does the Levonelle morning-after pill work?

Levonelle One Step prevents about 84% of expected pregnancies when it is taken within 72 hours (3 days) of unprotected sex. Levonelle One Step will not prevent a pregnancy in every instance, but the tablet is more effective the sooner after unprotected sex it is taken (it is better to take it within 12 hours rather than delay until the third day). The Levonelle One Step morning after pill is thought to work by:

• stopping your ovaries from releasing an egg
• preventing sperm from fertilising any egg you may have already released; or
• stopping a fertilised egg from attaching itself to your womb lining.

So Levonelle One Step stops pregnancy before it is established. It does not work if you are already pregnant.
