Important information

  • No method of contraception is 100% effective at preventing pregnancy.
  • When used correctly, condoms are the only method that also helps reduce the risk of sexually transmitted infections (STIs).
  • Contraception can cause side effects, which can vary from person to person, so some people may experience them, while others may not.
  • The time it takes to return to fertility after stopping contraception can vary depending on the method used.

Please talk to your healthcare professional if you’d like more information on contraception and to discuss your individual needs, including any plans for pregnancy after stopping use.
