Contraindications for Nexplanon
Nexplanon is absolutely contraindicated in women with current or past breast cancer, active liver disease or liver tumors, current/past thrombosis or thromboembolic disorders, undiagnosed abnormal uterine bleeding, known or suspected pregnancy, and allergic reactions to any component of the device. 1
Absolute Contraindications (US MEC Category 4)
Based on the FDA label and clinical guidelines, the following conditions represent unacceptable health risks:
Malignancy-Related
- Current breast cancer - This is the primary absolute contraindication for all contraceptive implants including Nexplanon 2, 3, 1
- Personal history of breast cancer 1
- Other progestin-sensitive cancers (current or past) 1
- Liver tumors (benign or malignant) 1
Vascular Conditions
- Current thrombosis or thromboembolic disorders 1
- Past history of thrombosis or thromboembolic disorders 1
This is a critical distinction from combined hormonal contraceptives - while progestin-only methods like Nexplanon are generally safe for women with thromboembolic disease history, the FDA label explicitly contraindicates it 4.
Other Absolute Contraindications
- Active liver disease 1
- Undiagnosed abnormal uterine bleeding 1
- Known or suspected pregnancy 1
- Allergic reaction to any component (etonogestrel, barium sulfate, magnesium stearate, or EVA copolymer) 1
Important Clinical Context
What is NOT a Contraindication
The guidelines emphasize that Nexplanon has remarkably few contraindications compared to combined hormonal contraceptives 2. Specifically, the following conditions are NOT contraindications:
- Cardiovascular disease (including congenital heart disease, valvular disease, MI, stroke) - US MEC Category 1 or 2 2
- Hypertension (even poorly controlled) - progestin-only methods are preferred 4
- Diabetes with complications 4
- Smoking at any age 4
- Obesity 3
- Systemic lupus erythematosus 2
- Epilepsy 2
- HIV infection 2
Critical Pitfall to Avoid
Do not confuse contraindications for combined hormonal contraceptives with those for Nexplanon. Many conditions that absolutely contraindicate estrogen-containing methods (like history of VTE, smoking over age 35, migraine with aura, uncontrolled hypertension) are actually appropriate indications for Nexplanon 2, 4. The implant is specifically recommended as the contraceptive of choice for women with these cardiovascular risk factors 4.
Relative Considerations (US MEC Category 3)
While not absolute contraindications, certain liver diseases warrant careful consideration, with risks usually outweighing benefits 3. However, the primary absolute contraindication remains active liver disease or liver tumors 1.
Postpartum Timing
In the immediate postpartum period (<21 days), Nexplanon is US MEC Category 2 (benefits outweigh risks), not contraindicated 5. This makes it an excellent option for immediate postpartum contraception in women at high risk for pregnancy-related complications 2.
