Long-acting reversible contraceptives (LARC) are methods of birth control that provide effective contraception for an extended period without requiring user action. They include hormonal and non-hormonal intrauterine devices (IUDs) and subdermal hormonal contraceptive implants. They are the most effective reversible methods of contraception because their efficacy is not reliant on patient compliance. The failure rates of IUDs and implants is less than 1% per year.
LARCs are often recommended to people seeking convenient and cost effective contraception.[1] In one study, LARC users saved thousands of dollars over a five-year period compared to those who buy condoms and birth control pills.[2] LARCs can generally be safely and effectively used by people of any body weight,[3] adolescents,[4] and people who have not yet had children.[5][6]
In 2008, the American College of Obstetrics and Gynecologists (ACOG) launched The Long-Acting Reversible Contraception Program with the intention to reduce rates of unintended pregnancy by promoting LARCs, often referred to as a "LARC-first" model.[7] Rates of LARC use in the United States rose steadily in that time frame, from 3.7% in 2007 [7] to 10% in 2019.[8] LARC methods are most popular amongst people in their late teens and early twenties.[9] LARC use varies globally, with different regions reporting different use rates.[10][11] An estimated 161 million people of reproductive age use an IUD and an additional 25 million use an implant; this is 19.4% of the estimated global population of women of reproductive age.[12]
