Long-acting reversible contraception

Long-acting reversible contraception (LARC) refers to birth control methods that provide effective contraception for an extended period without requiring user action. They include intrauterine devices (IUDs), subdermal implants, and hormonal and copper IUDs.

Types of LARC

There are two main types of LARC: intrauterine devices (IUDs) and implants.

Intrauterine devices

Intrauterine devices (IUDs) are small devices placed in the uterus to prevent pregnancy. They are long-term, reversible, and one of the most effective birth control methods available. There are two types of IUDs:

• Copper IUDs: These IUDs release copper to prevent pregnancy. They can stay in place for up to 10 years.
• Hormonal IUDs: These IUDs release progestin to prevent pregnancy. They can stay in place for 3 to 5 years, depending on the brand.

Implants

Contraceptive implants are thin, small (4 cm), flexible rods that are implanted under the skin of the upper arm by a healthcare provider. They release progestin to prevent pregnancy and can stay in place and provide effective contraception for up to 3 years.

Effectiveness

LARC methods are among the most effective forms of contraception. The failure rate for LARC methods is less than 1%, making them as effective as sterilization, but reversible.

Benefits and Risks

LARC methods have several benefits, including long-term, highly effective contraception that is not user-dependent and is reversible. They also have potential risks, including side effects, such as irregular bleeding, and in rare cases, serious complications like uterine perforation for IUDs.
