FAQs
Everything you need to know about emergency contraceptives.
How does emergency contraception work?
Levonorgestrel emergency pills mainly work by delaying or preventing ovulation. If an egg has not yet been released, sperm cannot fertilise it. They do not end an existing pregnancy.
How effective is it and when?
About 95% effective within 24 hours, ~85% within 48 hours, and ~58% within 72 hours. The sooner you take it, the better it works.
Is it safe while breastfeeding?
Yes. Levonorgestrel is considered safe during breastfeeding. You can continue breastfeeding as normal.
Will it affect my future fertility?
No. Emergency contraception does not affect your ability to get pregnant in the future. Your fertility returns to normal with your next cycle.
Can I use it more than once?
Yes, it is safe to use more than once if needed, but it is not designed as a regular method. If you find yourself needing it often, consider a daily or long-acting method.
Do I need a prescription?
No. Emergency contraceptives don't require a prescription. If you find yourself needing it often, we recommend chatting with our nurses about a regular contraceptive method.
Are there any safety concerns?
Emergency contraception is very safe for most people. Speak to a doctor if you have a history of severe liver disease, take certain epilepsy or TB medications, or are unsure.
