Long-acting reversible contraceptives (LARC), such as IUDs and implants, are highly-effective, nonpermanent methods for preventing pregnancy that do not have to be thought about on a daily, weekly, or even monthly basis. Once the method is removed, a woman’s fertility will quickly return and she will be able to get pregnant. LARC methods do not provide protection against STIs. You will still need to use a condom to reduce your risk of contracting STIs.

Nexplanon®

What is it?

Nexplanon® is a method of birth control that is a single matchstick- sized rod with progestin (a hormone) in it that is placed underneath the skin in your upper arm by a healthcare provider. Once inserted, a small amount of progestin is slowly and continuously released.  The progestin stops the release of the egg from the ovary.  Pregnancy cannot occur if there is no egg to join with sperm. The progestin thickens the cervical mucus making it more difficult for sperm to reach the egg.

How effective is it at preventing pregnancy?

Nexplanon® is more than 99% effective and prevents pregnancy for three years. Nexplanon® does not provide protection against sexually transmitted infection (STIs).

Who should use it?

Nexplanon®is a good choice for women who want a long-term method of birth control that is hidden and effective for a longer period of time. This method may be a good choice for women who are sensitive to or cannot use estrogen containing hormonal methods.

Mirena® IUS (Intra-Uterine System)

What is it?

Mirena® Progestin-Only Intrauterine System or IUS is a T-shaped device inserted into the uterus by a health care provider. The IUS is similar to an IUD but also contains a small dose of levonorgestrel, a progestin hormone found in many birth control pills. The hormone is slowly released over time and because of this, only small amounts enter your blood. The IUS prevents pregnancy by thickening cervical mucus to prevent sperm from entering your uterus, inhibiting sperm from reaching or fertilizing your egg, and thinning the lining of your uterus. The hormone in this IUS also decreases the amount of menstrual flow and cramping.  Women experience irregular bleeding patterns for the first 3 months after insertion and often have a significantly decreased flow and cramping once their body adjusts to the IUS.

How effective is it at preventing pregnancy?

The IUS is more than 99.5% effective and prevents pregnancy for up to 5 years. The IUS does not provide protection against sexually transmitted infections (STIs).

Who should use it?

Women who want to decrease the amount of bleeding and cramping during their periods, do not desire a pregnancy for an extended period of time and want the convenience of not having to do anything on an ongoing basis.

Skyla IUS

What is it?

The Skyla IUS, intrauterine system (otherwise known as an intrauterine device or IUD) is a small, T-shaped device that’s inserted into your uterus by a health care provider. It is made by the same company that makes the Mirena, and it works the same way, by releasing a low dose of levonorgestrel, a hormone that thickens cervical mucus and blocks sperm. The difference is that Skyla is slightly smaller, uses a slightly lower dose of hormone, and prevents pregnancy for 3 years instead of five.

How effective is it at preventing pregnancy?

Skyla is more than 99% effective and prevents pregnancy for up to 3 years. Skyla does not provide protection against sexually transmitted infections (STIs).

Who should use it?

Women who want all the benefits of the Mirena — convenient, long-term birth control and reduced cramping and bleeding during periods — but in a smaller package. Skyla’s slightly smaller size and narrower placement tube are intended to make it more comfortable to insert and use compared to other IUDs, especially for young women and women who haven’t had a child.

Liletta IUS

What is it?

Liletta is an IUS, intrauterine system (otherwise known as an intrauterine device or IUD) that is inserted into the uterus by a healthcare provider to prevent pregnancy. Liletta works the same way as Mirena and Skyla, by releasing a steady, low level of the hormone levonorgestrel into the uterus. Liletta releases about 19 micrograms per day for the first year, compared to about 20 micrograms per day with Mirena and 14 with Skyla. Most of the hormone stays in the uterus, but there is a measureable amount of it in the in the blood too (0.0002 micrograms per milliliter). All of these hormonal IUDs prevent pregnancy by thickening the cervical mucus and blocking sperm.

How effective is it at preventing pregnancy?

Liletta is more than 99% effective at preventing pregnancy for up to 3 years. Liletta does not provide protection against sexually transmitted infections (STIs).

Who should use it?

Women who want to decrease the amount of bleeding and cramping during their periods, do not desire a pregnancy for an extended period of time and want the convenience of not having to do anything on an ongoing basis. Liletta was tested and found effective in preventing pregnancy in a wide variety of women, regardless of age, body mass index (BMI), or whether or not they’d ever given birth.

Paragard® IUD

What is it?

Paragard® IUD (Intra-Uterine Device) is a T-shaped copper-releasing device inserted into the uterus by a health care provider. The IUD works by interfering with the movement of the sperm inside the uterus.  Sperm die within the uterus before they can fertilize the egg. The IUD may increase the amount of bleeding during your period and increase menstrual cramping.

How effective is it at preventing pregnancy?

Greater than 99% effective and prevents pregnancy for 10 or more years. The IUD does not provide protection against sexually transmitted infections (STIs).

Who should use it?

Women who want to avoid hormonal methods of birth control, do not desire a pregnancy for an extended period of time and want the convenience of not having to do anything on an ongoing basis.
