Emergency contraception you can count on

Q: How effective are emergency contraception pills?

It depends on how quickly you take them after unprotected sex: the sooner, the more effective. They can reduce the risk of pregnancy by 75 to 89% when taken within 72 hours (3 days). Some types work up to 5 days after sex, but their effectiveness drops over time.

Q: Are there any side effects?

Common side effects include nausea, fatigue, headache, dizziness, breast tenderness and changes in menstrual flow. These are usually mild and short-lived. If you vomit within two hours of taking the pill, you may need another dose.

Q: Can emergency contraception end an existing pregnancy?

No. Emergency contraception pills are designed to prevent pregnancy and will not work if you are already pregnant.

Q: How often can I use emergency contraception?

There is no strict limit, but it isn't recommended as a regular form of contraception. Frequent use can lead to irregular periods and is less effective than regular methods.

Q: Does emergency contraception protect against STIs?

No. It is designed only to prevent pregnancy. Using condoms is the best way to protect against sexually transmitted infections.

What are emergency contraception pills and how do they work?

Emergency contraception pills are a form of birth control that can be used to prevent pregnancy after unprotected sex, or if your regular method of contraception fails. They work mainly by delaying ovulation, which prevents fertilisation. Some types may also interfere with fertilisation of an egg or implantation of a fertilised egg in the uterus.
