Emergency Contraception

Emergency contraception is used after unprotected sex or a contraceptive failure. The most common types are Plan B (levonorgestrel) and Ella (ulipristal acetate). They should be taken as soon as possible after the incident (should be within 72-120 hours).

Plan B is available over the counter at most pharmacies. Plan B and Ella are available through the Health Service at a cost. You can speak to a health care provider here to determine if emergency contraception is an appropriate choice.
