Despite its proven effectiveness in clinical trials, the exact way that Levonelle works is not entirely understood. It’s thought that it works by preventing ovulation and fertilisation, and by also altering the womb’s natural lining, depending on which stage of your menstrual cycle you are in. Levonelle will stop pregnancy from taking place; it will not be effective if you have already become pregnant.
It has been shown to be 95% effective during the first 24 hours after sex. Clinical trials have also shown that during hours 25 - 48 it is 85% effective, but this drops to 58% effectiveness during 49 - 72 hours after sex. This pill is safe for the vast majority of women to take and causes only mild side effects in some cases.
Levonelle contains a one pill dose with 1.5 milligrams of levonorgestrel, an artificial hormone that has been used in contraceptive pills for more than 35 years.
You are not advised to use this if you are allergic to levonorgestrel. You are also not recommended to take this medication if you have liver disease, or any disease of the gut or bowel which might cause malabsorption.
When you fill out your consultation, be sure to include any details regarding any medications you are taking. If you are taking medication for TB, HIV, epilepsy or fungal infections, or taking a herbal supplement containing St John’s Wort, then you may not be able to use the emergency contraceptive pill.
You may take it at any time during your menstrual cycle. Take the tablet whole with water as soon as you can after unprotected sex. If you are using a regular form of contraception, you should continue to use it. You can only take emergency contraception once per menstrual cycle; we recommend using a barrier contraceptive, such as condom, until your next menstrual cycle to minimise the risk against unplanned pregnancy.
You might experience mild side effects after taking this emergency contraceptive, the most common being nausea. Less common side affects you could experience include breast tenderness, headaches, stomach pains, diarrhoea, dizziness and tiredness. You might have your period later after taking Levonelle, and could experience some spotting or bleeding before your next period.
