What is Levonelle One Step?

The morning after pill (emergency contraception) is not to be taken as a form of birth control. Emergency contraception does NOT protect you from sexually transmitted diseases or infections

Levonelle One Step is the brand-name version of Levonelle 1500, a morning after pill. Levonelle One Step can help prevent pregnancy in the event that other birth control methods have not been used or have failed. Levonelle One Step must be taken within 72 hours of sexual intercourse.


It is important to note that the morning after pill does not prevent the transmission of sexually transmitted infections (STIs).  Emergency contraceptive is not a form of abortion and cannot terminate a pregnancy.

Please be aware that the effectiveness of the pill decreases over time 

• 95% effective the first 24 hours after having unprotective sex

• 85% effective between 24 – 48 hours

• 58% effective between 48 – 72 hours

How does Levonelle One Step work?

Levonelle One Step has the active ingredient levonorgestrel which is a synthetic version of the female hormone progesterone. Levonelle One Step is thought to prevent pregnancy by:

  • Stopping your ovaries from releasing an egg
  • Preventing sperm from fertilising any egg you may have already released


Levonelle One Step only prevents pregnancy after sexual intercourse. If you take it before having sex, it will not stop you from becoming pregnant.

If you are suffering from domestic violence, emotional abuse, sexual exploitation/abuse or then please get in touch with someone from this list of helpful charities who can help you: Victim Support Page

How do you take Levonelle One Step?

Take the morning after pill as soon as possible after you have unprotected sex. Do not chew the tablet. Swallow it with water.


If you vomit within three hours of taking a Levonelle One Step tablet, you should take another one. You will need to contact your pharmacist or doctor to receive another morning after pill as soon as possible.

How effective is Levonelle One Step as an emergency contraception method?

The sooner Levonelle One Step is taken after sexual intercourse, the more effective it will be. If taken within 72 hours of intercourse, Levonelle One Step is an effective way of preventing pregnancy.

It is important to bear in mind that the morning after pill becomes less effective with time, so it’s important to take it as soon as possible after having unprotected sex.
