What is the Nexplanon contraceptive implant?

Nexplanon is a thin, flexible plastic that’s about the size of a matchstick and contains the hormone progestin. The implant is inserted under the skin of your upper arm, where it slowly and continuously releases hormones that prevent pregnancy.

How does Nexplanon work?

The hormone released by Nexplanon works two ways to ensure you don’t become pregnant:

  1. It prevents ovulation. An egg is not released from your ovaries, so it can’t be fertilized.
  2. It thickens cervical mucus. Thicker mucus prevents sperm from being able to travel through the cervix, so they can’t reach an egg.

How effective is the Nexplanon implant?

Nexplanon rates as one of the most effective methods of birth control. It’s more than 99% effective, which means it works just as well as permanent sterilization.

What makes Nexplanon a long-acting reversible contraceptive (LARC)?

After Nexplanon is inserted, it stays in place and continuously prevents pregnancy for three years. After that, it must be removed and replaced with a new implant, because it runs out of hormones.

It’s completely reversible. You can have it taken out at any time and become pregnant as early as a week after it’s removed.

How is Nexplanon inserted?

You’ll need to have a pregnancy test before Nexplanon is inserted, because you can’t use it if you’re pregnant. Then your doctor at Annandale Ob-Gyn & Primary Care numbs the area on your upper, inner arm where it will be implanted.

The doctor uses a specialized applicator to insert Nexplanon under your skin, and your procedure is finished. You’ll wear a pressure bandage for 24 hours and a bandage for three to five days.

When you want the implant removed or it’s time to replace it, your doctor makes a small incision and takes it out.

How soon does it begin to prevent pregnancy?

When Nexplanon is inserted within the first five days of your menstrual, it begins to work immediately. If it’s inserted any time after five days, you’ll need to wait a week before it’s effective, so you should avoid sex or use condoms until then.

Will Nexplanon affect your menstrual periods?

In some women, Nexplanon may change menstrual bleeding. You may have longer or short periods or you may not have any periods. Additionally, the time between your periods may vary and you could have spotting.
