Implant Birth Control: Everything you NEED to know about the Nexplanon

Hormonal implants work more than 99% of the time. How do they stack up to other birth control methods?

  • Intrauterine devices 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 . Only condoms prevent STDs.

If You’re Under 16 Years Old

Contraception services are free and confidential, including for people under the age of 16.

If you’re under 16 and want contraception, the doctor, nurse or pharmacist won’t tell your parents as long as they believe you fully understand the information you’re given, and your decisions.

Doctors and nurses work under strict guidelines when dealing with people under 16. They’ll encourage you to consider telling your parents, but they won’t make you.

The only time a professional might want to tell someone else is if they believe you’re at risk of harm, such as abuse. The risk would need to be serious, and they would usually discuss this with you first.

Nexplanon has also been working to thin the lining of your uterus, potentially making it more difficult for an embryo to implant immediately after Nexplanon is removed. It thickens back up quickly for most women , but it is best to give it a couple of cycles to recuperate. Dont be discouraged if pregnancy does not happen immediately, and keep in mind that pregnancy immediately of removal could carry a slightly increased risk for miscarriage.

If you have been using Nexplanon or other forms of birth control for many years, also keep in mind that age affects egg quality and chance of pregnancy. Every year after about age 25 your fertility slowly declines, making it ever so slightly more difficult to get pregnant as you age. Be patient with your body. Give it a full year of trying before considering infertility.

How Effective Is The Implant At Preventing Pregnancy

The implant is a very effective method of long-acting contraception, and while no form of contraception is completely failsafe, using it makes the risk of getting pregnant far less likely.

It is estimated that 84% of people with a womb would get pregnant within a year if they had regular, unprotected intercourse.3

For people using the contraceptive implant, the chances of getting pregnant are less than 1%, providing the implant has been in place for less than three years.4 So, for every 100 people with an implant having intercourse, less than one will become pregnant over the course of one year.

This number is similar to the efficacy of the combined oral contraceptive pill .

While your implant is in place, it releases a steady amount of the hormone progesterone. However, the amount it releases decreases slightly year on year. This is why it needs replacing after three years. Research has shown that during this three-year period, the implant becomes no less effective at preventing pregnancy, however.5

According to available evidence, neither body weight nor BMI affects the effectiveness of the implant.6

Other methods of contraception including the copper coil, the Mirena coil, and the contraceptive injection, all have similar failure rates to the implant. If you compare this to the withdrawal method, which has a 27% rate of pregnancy within a year when used typically,7 you will see why this is not a recommended method of contraception.

What To Expect After Nexplanon Insertion

For starters, its important to mention that Nexplanon is an improved version of its predecessor Implanon. In that sense, the Nexplanon implant is completely visible on X-ray, CT scan, ultrasound, etc. Whats more, the applicator used to insert Nexplanon is considerably more efficient to operate as well.

Now, what to expect after Nexplanon insertion in terms of effectiveness? This particular birth control method is known to be 99.9% effective, making it one of the best contraceptives available today.

But can Nexplanon stop working early? While the implant wont just break on its own, its important to mention that it may be less effective in women who are overweight. In that respect, it might be necessary to replace the implant sometime after the second year of having it instead of waiting for the full three years to pass. This is because a higher BMI in overweight women lowers the number of active hormones in the blood.

Also, the common antibiotics shouldnt affect the effectiveness of Nexplanon. However, TB and meningitis antibiotics, as well as some HIV and epilepsy meds could lessen the effectiveness of this birth control. This doesnt mean that Nexplanon can stop working early, but its worth being a bit more careful with pregnancy protection. Also, taking herbal meds containing St Johns Wort could lower the implants effectiveness.
