LARC is a Long Acting Reversible Contraceptive method. 

They are 99% effective at preventing pregnancy. Your ability to have a baby (fertility) will return as soon as you take it out. 

They do not protect from STIs.

LARCs can only be inserted and removed by specially trained staff.

Intrauterine device (IUD)

  • A mirena is 99.8% effective at preventing pregnancy.
  • Periods usually become lighter or stop when using a Mirena.
  • It works by: 
    • stopping the release of ova (eggs), 
    • thickening the fluid around the cervix to make it harder for the sperm to get to the ovum (egg), and 
    • changing the lining of the womb to stop a fertilised egg from sticking to it (implanting).

  • It is 99.7% effective at preventing pregnancy.

  • It works by: 
    • stopping sperm from reaching and fertilising the ovum (egg),
    • affecting the way sperm move and survive in the uterus, and
    • changing the lining of the womb to stop a fertilised egg from sticking to it (implanting).

Implanon, or ‘The Bar’ 

  • Implanon works for 3 years
