Nexplanon (etonogestrel implant) is a contraceptive implant indicated for use by women to prevent pregnancy for up to three years. Nexplanon is available in generic form. Side effects of Nexplanon include:
- changes in menstrual periods,
- irregular menstrual periods,
- mood changes,
- breast tenderness or pain,
- abdominal pain,
- back pain,
- changes in appetite,
- vaginal infection or inflammation,
- vaginal discharge,
- sore throat,
- flu symptoms,
- injection site pain,
- ectopic pregnancies,
- liver disease,
- weight gain,
- nervousness, and
- fluid retention.
Serious side effects of Nexplanon include:
- blood clot formation,
- liver disease,
- ectopic pregnancy and
- serious depression;
- the side effects may warrant the removal of the implant.
Nexplanon (etonogestrel implant) is available in a sterile disposable container that has non-biodegradable polymer, 4 cm long by 2 mm wide, containing 68 mg of etonogestrel. A single Nexplanon implant is inserted, using sterile technique, subdermally in the upper arm by individuals trained to do this technique. Nexplanon may be used during breastfeeding after the fourth postpartum week. There is no evidence that the risk associated with etonogestrel is different from that of combination oral contraceptives. Nexplanon should be removed if a person becomes pregnant and is interested in maintaining the pregnancy, but it is imperative to rule out pregnancy before inserting the implant. The implant should be removed at the end of three years; another can be inserted if the patient still wants pregnancy prevention. This implant has not been studied in female patients under age 18.
Our Nexplanon (etonogestrel implant) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

Nexplanon FDA Prescribing Information: Side Effects
The following adverse reactions reported with the use of hormonal contraception are discussed elsewhere in the labeling:
- Changes in Menstrual Bleeding Patterns [see WARNINGS AND PRECAUTIONS]
- Ectopic Pregnancies [see WARNINGS AND PRECAUTIONS]
- Thrombotic and Other Vascular Events [see WARNINGS AND PRECAUTIONS]
- Liver Disease [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical trials involving 942 women who were evaluated for safety, change in menstrual bleeding patterns (irregular menses) was the most common adverse reaction causing discontinuation of use of the non-radiopaque etonogestrel implant (IMPLANON) (11.1% of women).
Adverse reactions that resulted in a rate of discontinuation of ≥ 1% are shown in Table 3.
Table 3: Adverse Reactions Leading to Discontinuation
of Treatment in 1% or More of Subjects in Clinical Trials of the Non-Radiopaque
Etonogestrel Implant (IMPLANON)
|Adverse Reactions||All Studies
N = 942
|* Includes “frequent”, “heavy”, “prolonged”, “spotting”,
and other patterns of bleeding irregularity.
†Among US subjects (N=330), 6.1% experienced emotional lability that led to discontinuation.
‡Among US subjects (N=330), 2.4% experienced depression that led to discontinuation.
Other adverse reactions that were reported by at least 5% of subjects in the non-radiopaque etonogestrel implant clinical trials are listed in Table 4.

of Subjects in Clinical Trials With the Non-Radiopaque Etonogestrel Implant
|Adverse Reactions||All Studies
N = 942
|Insertion site pain||5.2%|
In a clinical trial of NEXPLANON, in which investigators were asked to examine the implant site after insertion, implant site reactions were reported in 8.6% of women. Erythema was the most frequent implant site complication, reported during and/or shortly after insertion, occurring in 3.3% of subjects. Additionally, hematoma (3.0%), bruising (2.0%), pain (1.0%), and swelling (0.7%) were reported.
The following additional adverse reactions have been identified during post-approval use of IMPLANON and NEXPLANON. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Gastrointestinal disorders: constipation, diarrhea, flatulence, vomiting.
General disorders and administration site conditions: edema, fatigue, implant site reaction, pyrexia.
Immune system disorders: anaphylactic reactions.
Infections and infestations: rhinitis, urinary tract infection.
Investigations: clinically relevant rise in blood pressure, weight decreased.
Metabolism and nutrition disorders: increased appetite.
Pregnancy, puerperium and perinatal conditions: ectopic pregnancy.
Psychiatric disorders: anxiety, insomnia, libido decreased.
Renal and urinary disorders: dysuria.
Vascular disorders: hot flush.
Complications related to insertion or removal of the etonogestrel implants reported include: bruising, slight local irritation, pain or itching, fibrosis at the implant site, paresthesia or paresthesia-like events, scarring and abscess. Expulsion or migration of the implant have been reported, including to the chest wall. In some cases, implants have been found within the vasculature, including the pulmonary artery. Some cases of implants found within the pulmonary artery reported chest pain and/or dyspnea; others have been reported as asymptomatic [see WARNINGS AND PRECAUTIONS]. Surgical intervention might be necessary when removing the implant.
