What is a LARC?
Posted on Tuesday, December 1st, 2015 at 7:38 pm
- LARC stands for long acting reversible contraception. This category includes intrauterine contraception (IUCs/ IUDs) which can last for 3-10 years, and implanted devices (Nexplanon®) which are effective for up to three years.
- LARCs are >99% effective at preventing pregnancy. That is as effective as permanent sterilization procedures!
- All LARCs are completely reversible. After removal, resumption in fertility is almost immediate.
- LARCs are safe for most women and teens, even if you’ve never had a baby.
- If you are not a candidate for hormonal birth control like birth control pills, a LARC may be appropriate for you.
- The ParaGard® device may also be used as emergency contraception within 120 hours of unprotected intercourse.
- Some LARCs may also provide non-contraceptive benefits like shorter, lighter periods.
