About emergency hormonal contraception

Emergency hormonal contraception (EHC) is also called the 'morning after pill'. If you have had unprotected sex, taking emergency hormonal contraception within 3-5 days can help prevent pregnancy. The pill should be taken as soon as possible after unprotected sex - the earlier it is taken, the more effective it is. EHC can be used if you have had sex without using contraception, or if you have had sex but there was a mistake with your usual contraception (for example, a split condom or if you forgot to take your usual contraceptive pills).

There are two types of 'morning after pill' available. One contains a medicine called levonorgestrel which is a female progestogen hormone. The other contains a medicine called ulipristal acetate which works on female hormone receptors within your body. They are both thought to work mainly by delaying or stopping your ovaries from releasing an egg.

Although EHC is effective, it is not as reliable as regular planned contraception. Therefore, it should only be used in an emergency.

Der levonorgestrel pill is available free on prescription as brands called Levonelle®, LoviOne® and Upostelle®. It can also be purchased from a pharmacy, without a prescription, as a brand called Levonelle® One Step. It is effective for up to 72 hours (three days) after unprotected sex.

Der ulipristal acetate pill is effective for up to 120 hours (five days) after having unprotected sex. Ulipristal acetate is available free on prescription through a doctor or family planning clinic as a brand called ellaOne®. It can also be purchased from a pharmacy, without a prescription.

A non-hormonal method of emergency contraception is also available. An intrauterine contraceptive device (IUCD) can be inserted by a doctor or nurse up to five days after unprotected sex. This method of emergency contraception is more effective than hormonal tablets. Your doctor can give you more information about this.

Before taking emergency hormonal contraception

To make sure this is the right treatment for you, before you take the 'morning after pill' it is important that your doctor or pharmacist knows:

• If there is a possibility that you could already be pregnant.

• If you are breastfeeding.

• Wenn Sie Probleme mit der Funktion Ihrer Leber haben.

• If you have severe asthma.

• If you have ever had an ectopic pregnancy.

• If you have a condition of your small bowel that interferes with the way you absorb food, such as Crohn's disease.

• Wenn Sie eine seltene erbliche Bluterkrankung namens Porphyrie haben.

• Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.

• If you are taking other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines. This is important because some medicines reduce the effectiveness of EHC. These include some medicines for epilepsy, two antibiotics called rifampicin and rifabutin, a herbal remedy for low mood, called St John's wort, some medicines used to treat HIV and AIDS, and some medicines taken for indigestion and heartburn.

How to take emergency hormonal contraception

• Before you take the tablet, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about the brand of pill you have been given and the side-effects from taking it. Take it exactly as you have been told.

• The pack contains one tablet. Take the tablet as soon as possible, as it works better the sooner you take it. Levonorgestrel (called Levonelle®1500, Levonelle® One Step, Upostelle®) is best taken within 12 hours after unprotected sex - do not take it later than 72 hours after unprotected sex unless you have been advised otherwise by a doctor. Ulipristal acetate (ellaOne®) should be taken no later than 120 hours after unprotected sex.

• You can take the tablet at any time of day. Although you can take the tablet either before or after food, it is better to have a snack as you take the tablet if possible. This will help to reduce the risk of you feeling sick after taking the tablet. However, don't let this delay you taking the tablet.

• If you are sick within three hours of taking the tablet then you should take another tablet as soon as possible. You will need to get a further supply through your doctor or pharmacy.

• For some women your doctor may prescribe two levonorgestrel tablets, to be taken together at the same time. This will usually only happen if you are taking certain other medicines that affect how well levonorgestrel works.

Das Beste aus Ihrer Behandlung herausholen

• EHC is for occasional use only. It should not be relied upon as a regular method of contraception. Do not use EHC more than once in the same menstrual cycle.

• Taking the 'morning after pill' will not provide protection against pregnancy for the rest of your cycle. If you are already using a regular method of contraception such as the contraceptive pill, you should continue to take this at your regular times, although you should also use a condom or avoid having sex until your next period.

• Your next period may occur a few days earlier or later than expected. If your periods are delayed by more than about 5-7 days, or if your bleeding is unusual in any way, see your doctor for further advice. Even if you have taken the tablet correctly, there is still a small risk of pregnancy and a pregnancy test may be advised.

• If you have any pain in your lower tummy (abdomen) or any unusual vaginal bleeding in the following few weeks, you should see a doctor. These may be signs of an ectopic pregnancy, and although this is rare, it is best to be aware of the possibility as it is a serious condition.

• EHC will not protect you against sexually transmitted infections. Speak with your pharmacist, doctor or clinic if you are concerned about this and need advice.

Can emergency hormonal contraception cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common side-effects associated with EHC. You will find a full list in the manufacturer's information leaflet supplied with your tablet.

If you experience other symptoms which you think may be due to the tablet, speak with your doctor or pharmacist for further advice.
