Morning After Pill

The morning after pill is a method of contraception after unprotected sex. It doesn't matter why it happened - because of a missed pill or a split condom. While using the morning after pill, you need to remember that emergency contraception is really effective if it's taken in the right moment. 

The only two morning after pills available in the UK are Levonelle and ellaOne. You can order it here by getting the prescription.


What is the morning-after pill?

The Morning-after pill is an emergency contraception method to avoid pregnancy. This method of contraception pill can be used when you have unprotected sexual intercourse. There are some options in the market and to start thinking if you should use it or not, always pay attention, how and when to use it and the possible side effects.

How morning-after pills work?

In the market, there are two types of emergency contraceptive pills: 


EllaOne has ulipristal acetate, which stops progesterone hormone to work properly.  This medicine can also delay or stop the release of an egg (ovulation). You can use it until 120 hours (5 days) after unprotected sexual intercourse to avoid pregnancy. It is recommended to be sure you are not pregnant before you take it. i


Levonelle has levonorgestrel, which is a synthetic version of the hormone progesterone produced by the ovaries. This medicine can also delay or stop the release of an egg (ovulation). You can use it until 72 hours (3 days) after unprotected sexual intercourse to avoid unwanted pregnancy.

How can you use it?

If you had sex without protection and you do not want to be pregnant, you can consider the possibility to take this pill.  You can also consider the possibility to take it, if your primarily method of contraception failed for some reason. For example, if you forgot to take one birth control pill or if the condom broke.

The morning-after pill is a good decision to avoid unwanted pregnancy but it is not intended to be used as a regular form of contraception method. This method does not continue to protect you against pregnancy.  If you had unprotected sex after taking the emergency pill, you can become pregnant. Nevertheless, if you need it more than one time in a menstrual cycle, you can also use it.

How effective are morning-after pills?

No contraception method is 100% effective in all cases, but this method is very reliable to avoid unwanted pregnancy. The effectiveness of morning-after pills depend how soon you take it after sexual intercourse. EllaOne is a morning pill that you can use it until 120 hours after the intercourse. Studies have shown that 95% of women are protected , if morning after pills are taken between 48 to 120 hours after sexual intercourse.

Levonelle is one of the most common pills prescribed in the UK and the effectiveness are:

  • It is 95% effective if you take within 12 hours after unprotected sex;
  • It is 85% effective if you take between 12 to 24 hours after unprotected sex;
  • It is 75% effective if you take between 24 to 48 hours after unprotected sex;

  • There are also some discussions about moral conscience, a kind of aggression against the human embryos;

They have also some critics, which support the idea of this medicine to be kept without a prescription, which are:

  • In most of the countries, the rate of unsafe sex did not increase after the liberation of emergency pill without prescription;
  • This medicine can prevent a great number of unwanted pregnancies and possible abortions, which is more dangerous for women’s body;
