What Is the Birth Control Implant?
The implant available in the U.S. is Nexplanon. It’s a newer version of the implant Implanon. You might hear people call them arm bars.
How Does the Implant Work?
Once the implant is placed under your skin, it releases small amounts of etonogestrel. The hormone works on your pituitary gland, which tells your ovaries not to release eggs. It also makes the mucus in your cervix thicker. This makes it harder for sperm to get to any eggs that are released.
How Effective Is the Birth Control Implant?
Hormonal implants work more than 99% of the time. How do they stack up to other birth control methods?
- Intrauterine devices (IUDs) are also 99% effective.
- Birth control injections are 94% effective.
- The pill is 91% effective.
But none of these methods protect you from sexually transmitted diseases (STDs). Only condoms prevent STDs.
How Long Does the Birth Control Implant Work?
You can use a birth control implant for up to 3 years. Then you need to get it replaced.
What Are the Benefits of the Implant?
As with any type of birth control method, implants have pros and cons.
- They work. Fewer than 1 in 100 women using an implant will get pregnant each year.
- Easy to use. Unlike some birth control options -- like condoms, patches, shots, rings, and pills -- the implant works no matter what. You don't have to worry about using it incorrectly or remembering to replace or take it often.
- Fast reversal. If you want to get pregnant, you can get started on that right after you get the implant taken out.
- Less painful periods. In studies of women using implants, painful periods got better.
- Lighter or no periods. Your period might get shorter, or even stop completely.
What Are the Drawbacks to the Implant?
Some problems with birth control implants include:
- Cost. You may have to pay about $600 or more for an exam and the implant, and $100 or more to have it removed.
- No protection against STDs. Birth control implants won't prevent HIV or any sexually transmitted diseases. Use a condom for that.
Birth Control Implant Side Effects

- Bruising or swelling

- Irregular menstrual bleeding

What to Expect at the Doctor's Office
Then they'll use a tool that pushes the rod in through a needle. That won’t hurt. It feels like a little bit of tugging. The process may take less than a minute.
Afterward, you should be able to feel the implant under your skin but not see it.
Birth Control Implant Removal
Taking out the implant is quick and simple. Don’t try to do it yourself. Your doctor needs to remove it. While you’re in the office they’ll:
- Mark the spot on your arm where the implant is
- Clean the area to prevent infection
- Give you a shot with medicine to numb the site
- Make a small cut at the top of the implant and remove it
It could take as long as 20 minutes if there’s a lot of scar tissue in the area. If the doctor can’t easily find the implant, they might take an X-ray to locate it.
Your arm might be sore after the implant comes out. You’ll need to:
- Wear a bandage for 48 hours
- Keep the area dry for 24 hours
