Emergency Contraception
© 2007 Dr. Len Kliman 
Each year there are many unplanned and often unwanted pregnancies due to lack of contraception or contraception failure. Although effective contraception is readily available, there are times when a condom will break or a woman will forget to take her pill. Emergency contraception provides a safe and effective emergency method for birth control in such situations.
Whilst there are a number of emergency contraceptive methods available, they require use preferably within 24 hours of intercourse. As they are not as effective as the pill or condoms, they should not be used as a routine contraceptive method. Daily, correct use of the contraceptive pill prevents 97 -99% of pregnancies whilst the emergency method has about an 85% success rate. Therefore as the name implies, it should be used for emergency use only.
The most common method of emergency contraception involves taking Postinor-2.
This can be purchased without a script from a pharmacy.
Take one tablet as soon as possible (within 72 hours) after you have had unprotected intercourse. Take the second tablet 12 hours after the first tablet.
It is thought that Postinor-2 works by:
• Stopping the ovaries from releasing an egg
• Prevents sperm from fertilizing any egg that may have been released
• Stops a fertilized egg from attaching itself to the lining of the uterus
Prostinor-2 helps stop a pregnancy before it is established. It does not work if you are already pregnant.
There are some medical conditions such as Crohn’s disease, liver problems and high blood pressure that may make this type of medication unsuitable for you. There are also certain medications that may prevent Postiner-2 from working effectively. It is important that you discuss this with your doctor.
Like most medications there may be side effects with taking Postinor-2. These include nausea, irregular spotting, tender breasts and mild gastro intestinal symptoms.
You should expect a period within 21 days of taking Postinor-2 and if this does not happen it is important to consult your doctor to rule out pregnancy.
