The Morning-After Pill, or Levonelle:
The morning-after pill can be taken up to 72 hours after unprotected sex, if you forget to take a pill, if a condom splits on you or in any other circumstances which may lead to an unwanted pregnancy.

Up until recently, the first pill needed to be taken as soon after sex as possible, followed by the second 12 or 24 hours later, depending on the brand. This lead to confusion about its use and efficiency.

This method has been dramatically simplified, with both pills now being taken together, within 12 hours after sex if possible. Effectiveness falls to 95% if they are taken within 24 hours and 58% if they are taken between 48 and 72 hours afterwards. Contrary to 1990s versions, which were well-known for nausea, there are now very few side-effects.

Where can I get it?
If you need the morning-after pill, known as the PCP in the medical profession, you can get it from:
Your GP - make sure that the receptionist knows that the situation is urgent and gives you the next available appointment.
A Family Planning Clinic - ring 020 7837 5432 to find your nearest one.
A Brook Advisory Clinic - ring 0800 0185 023 to find your nearest one.
A GUM (Genitourinary Medicine) clinic or STD clinic in your local hospital.
Your university or college health centre - phone beforehand if necessary and make sure that they are aware the matter is urgent.
Some chemists - a lot of pharmacies will supply it over-the-counter without a prescription. In 2005, the cost was around £24, although in some areas, arrangements have been made to offer it for free. It is a good idea to call to make sure, before going to the chemist.

Wherever you get the morning-after pill, medical professionals will be on hand to explain how to take it. As it is more effective if taken early, it is worth asking for a glass of water there and then, to take the pills as soon as you have them.
