The information provided below lists common dosage information about Nexplanon.

What is Nexplanon’s form?

Nexplanon comes as a small, rod-shaped implant. Your doctor or another healthcare professional will place it just under the skin of your upper arm.

Dosage for preventing pregnancy

One Nexplanon implant can be used for up to 3 years. After your doctor removes it, you can choose to have a new implant inserted. This can be done at the same appointment as your removal.

Nexplanon can be removed sooner than 3 years if you and your doctor determine it’s not right for you.

Is Nexplanon used long term?

Yes, Nexplanon is a long-term birth control option. If you and your doctor determine that it’s safe and effective for you, you’ll likely have it implanted for 3 years. After your doctor removes your Nexplanon implant, you can choose to have a new one inserted.

Below are answers to some commonly asked questions about Nexplanon’s dosage.

After Nexplanon is inserted, what’s the daily dose of the drug that’s released into my body?

The Nexplanon implant contains a total dose of 68 milligrams (mg) of etonogestrel. This amount is slowly released into your bloodstream over 3 years (the maximum time you can use one implant). The average daily dose you receive changes slightly over the course of 3 years.

For the first 5–6 weeks, Nexplanon releases a dose of 60–70 micrograms (mcg) of etonogestrel per day. By the end of the first year, the dose is reduced to about 35–45 mcg per day. In the second year, the dose per day is about 30–40 mcg. By the end of the third year, the dose is about 25–30 mcg per day.

If you have questions about the Nexplanon dose that’s released into your body, talk with your doctor or pharmacist.

If I have problems with the Nexplanon implant, can I have it removed early?

Yes, you can. One Nexplanon implant can be used for up to 3 years, but you can have it removed earlier than that. (Nexplanon must be placed and removed by your doctor or another healthcare professional.)

Reasons to have Nexplanon removed early may include if you experience bothersome side effects or if the implant becomes damaged. Damaging a Nexplanon implant is rare, but it could occur if the area where it’s implanted is injured. This could cause the implant to bend or break.

If you want to have Nexplanon removed early, talk with your doctor about other birth control options.

Nexplanon is a small, rod-shaped implant that goes just under the skin of your nondominant upper arm. (So if you’re right-handed, the device would be placed in your left arm, or vice versa.) Your doctor or another healthcare professional will insert Nexplanon for you.

You can use one implant for up to 3 years. After your doctor removes it, you can choose to have a new implant inserted. This can be done at the same appointment as your removal.

If you have questions about how Nexplanon is placed or removed, talk with your doctor.

The sections above describe the usual dosage provided by the drugmaker.
