WHAT IS LONG-ACTING REVERSIBLE CONTRACEPTION (LARC)?

LARC (birth control) methods include:

  • The copper intrauterine device (IUD)
  • IUDs that contain a small amount of the hormone levonorgestrel - Mirena® (52 mg intrauterine levonorgestrel delivery system) and Jaydess® (13.5 mg intrauterine levonorgestrel delivery system)
  • The implant Jadelle® (2X75 mg levonorgestrel subcutaneous implants)


LARC methods are very effective at preventing unplanned pregnancy because they work without you having to remember to do anything on a regular basis – like take a pill every day or make an appointment to get an injection every 3 months. This is why LARC is sometimes called “fit and forget” contraception. However, you do need to make sure you have your LARC replaced at the right time. This depends on your LARC method.

Where are LARC methods used?

HOW EFFECTIVE ARE THE DIFFERENT CONTRACEPTIVE METHODS?

LARC methods are some of the most effective forms of contraception available - comparable to permanent contraception - but with the benefit of being completely reversible if you change your mind and want to get pregnant.

WHAT IF I DECIDE THAT I WANT TO HAVE A BABY?

LARC methods are completely reversible. This means that if you decide you would like to have a baby, you can have your LARC removed and return to your normal level of fertility right away.

And, if you already have a baby, LARC methods don’t contain estrogen and won’t affect how much breast milk you produce, so you can use them if you are breastfeeding.
