Implanon Discontinued Contraceptive

May 24, 2018


As of November 2011, the FDA has approved using Nexplanon in the United States, a newer variant of Implanon. Besides a few minor alterations, such that Nexplanon is radiopaque and contains a slightly different applicator/insertion procedure, Nexplanon is almost identical to Implanon.


Implanon was a type of birth control enhancer, receiving FDA-approval in July 2006.

This contraceptive implant is a thin rod, 40 mm in length and 2 millimeters in diameter–about the size of a cardboard matchstick. It had been created by a flexible plastic and is inserted just beneath the skin on the interior side of your upper arm. Implanon is a progestin-only procedure and provides about 3 decades of pregnancy protection. Insertion requires a local anesthetic and only requires a few minutes. The implant can be removed anytime before the 3 years are up. Implanon doesn’t contain silicone or latex and won’t dissolve, so it has to be taken off.

The Way It Worked

Implanon always releases a low dose of etonogestrel (a progestin) to protect against pregnancy for up to 3 years. It comprises 68 mg of etonogestrel, released over the 3-year period; about 60 to 70 micrograms per day have been published from the very first year, and the amount declines over time. After the third season, Implanon will still release some hormone, but it will not be enough to avoid pregnancy.

Negative Effects

Besides irregular bleeding, the most frequent side effects causing women to stop using Implanon include mood swings, weight gain, breast tenderness, headache, acne, and melancholy.

There is a slight risk that you will get a scar from removal or insertion of Implanon.

Possible Interactions

Considerable problems with Implanon are infrequent, yet it’s critical to report any complications to your physician right away.

  • Insertion: Sometimes Implanon is not inserted since the augmentation has fallen out of the needle. After insertion, you need to be able to feel the implant under your skin. If you cannot feel it, tell your health care provider immediately. Implant website complications were experienced by 3.6percent of clinical research participants. Pain was the most typical implant site complication, reported during and/or after insertion, happening in 2.9percent of subjects. Furthermore, hematoma, redness, and swelling have been reported by 0.1percent to 0.3percent of girls.
  • Removal: elimination of Implanon could possibly be difficult or impossible due to the implant not being where it should. If Implanon cannot be removed, then its effects will continue for a longer period of time. Removal complications occurred in 1.7percent of participants and included: augmentation couldn’t be sensed, damaged or broken augmentation, hard localization, and slight movement.

How to Obtain It

You may no longer obtain Implanon. If you want to know more about a breast augmentation, ask your physician about Nexplanon.


Implanon is 99.9% effective. This implies that out of every 100 women using Implanon in one year, less than 1 will become pregnant with typical use in addition to with perfect use.

The effectiveness of Implanon decreases if it’s been in place for more than 3 years.

STD Protection

Implanon offers no protection against sexually transmitted infections.

Locate a Qualified Implanon Doctor: Implanon has been phased out and replaced with its newer version, Nexplanon. Nexplanon allows for more accuracy during the insertion process and, like Implanon, must be added and removed by a trained healthcare provider. Trained healthcare providers have finished a Merck clinical training plan on Nexplanon.
