Product information

Levonelle is an emergency birth control pill, which you can only buy in the UK with a prescription. It is designed for cases where a primary method of contraception has failed, or not been used. Examples of this might be a ripped condom, broken birth control diaphragm, or cases where a user has forgotten to take a regular contraceptive pill.

  1. 84% effective when used within 72 hours
  2. Simple one-time treatment
  3. Popular and branded product

Manufactured by Bayer, Levonelle is estimated to have an 84% success rate when it is applied within 72 hours (or 3 days) of unprotected sex; however it is thought to be even more effective the sooner it is applied. Ideally, it should be taken within 12 hours of unprotected sexual intercourse. It should never be used more than 72 hours afterwards.

Before explaining how Levonelle 1500 prevents pregnancy, it is essential first to know what processes the female reproductive system goes through in order to prepare for potential pregnancy. Ovulation takes place every month, and involves the release of an egg from the ovary, into the womb. After it has emerged, this egg is ready for penetration by sperm. If the egg is successfully fertilised, it then migrates to the uterus and attaches to the endometrium, where it begins its maturation into an embryo.

The process of ovulation is managed by a hormone called progesterone, which also plays a part in determining the density of fluid in the cervix. Eggs are produced by the ovary when levels of this hormone drop.

The active constituent of Levonelle is an artificial version of this hormone called levonorgestrel. It stops the generation of an egg by convincing the body that ovulation has already occurred, and performs an additional contraceptive function by thickening cervical fluid. This stops an egg from being there for a sperm to inseminate; and makes it harder for sperm to reach an egg which is present.

Emergency contraception is not an alternative to primary methods of birth control. But it can work to reduce the chances of pregnancy beginning in some situations.

If a barrier method such as a condom has split or failed to work during sex, then you should discuss the potential risks of STIs with your GP. If you are not in a monogamous relationship, a doctor may recommend that you take an STI test.

If you are not using a long-term method of contraception, such as the birth control pill, then it may be of benefit to you to discuss this with your doctor.
