Long acting reversible contraception

Long-acting reversible contraception (LARC) is the collective name for intrauterine contraception (copper intrauterine devices and levonorgestrel intrauterine systems) and the subdermal contraceptive implant. LARC methods are highly effective, require minimal user effort and do not require regular healthcare appointments; however the insertion and removal procedures can only be undertaken by clinicians trained to do so. The progestogen-only subdermal implant is the most effective method of reversible contraception in the United Kingdom and is licensed for 3 years. The copper intrauterine device is the most effective non-hormonal method of contraception. These devices are licensed for five or 10 years and can also be used as emergency contraception. The levonorgestrel intrauterine systems (LNG-IUS) are licensed for 3, 5, or 6 years. The Mirena LNG-IUS is also licensed for use in treating heavy menstrual bleeding and for endometrial protection as part of hormone replacement therapy.
