The Implant

What is it?

The birth control implant, also called by the brand name Nexplanon, lasts up to five years and is a long-acting reversible contraception (LARC). A small, thin, plastic rod about the size of a matchstick is inserted into your upper arm by a doctor. Your arm will be treated with a local anesthetic, and there will be a bit of discomfort during the insertion. It takes no more than five minutes. You can’t see the implant once it’s in, and you can’t feel it unless you press that area, but you may develop a small scar at the insertion point.

How does it work?

Like the shot, the implant contains progestin only. It gives off a very small amount of the hormone continuously to prevent pregnancy. Progestin works by thickening the cervical mucus so that sperm cannot successfully swim through it, and can also prevent ovulation altogether. One month after insertion, you have a check-up with your doctor to check the insertion spot and address any questions or concerns. After three to five years, you return to your doctor to have the implant removed or replaced.

The birth control implant is 99.5% effective.


  • Just like the shot, this method is long-lasting, invisible, nothing to remember, and essentially worry-free.
  • It also tends to produce lighter or fewer periods or no periods at all. According to Planned Parenthood, after one year of using the implant, one-third of users will stop having periods completely.



The price ranges between $400 to $800 to cover the cost of the exam, implant, and insertion. This is a lot of money upfront, but it is a one-time cost every three to five years, for as long as you keep getting the implant. Removal typically costs between $100 and $300.  Nexplanon may be covered by your health insurance.

Where to Get It

Talk to your doctor, gynecologist, or a health or family planning clinic (like Planned Parenthood). Not all doctors insert implants or are experienced in insertion and removal. Check to make sure there are no additional costs.
