- Report abdominal pain, suspected pregnancy, or implant issues to your doctor immediately.

- Temporary pain, irritation, or bruising at the insertion site
- Changes in menstrual bleeding (shorter, longer, spotting, or no bleeding)
- Weight gain
- Headache

- Mood swings or depression
- Symptoms of an allergic reaction include rash, hives, itching, chills, fever, headache, muscle ache, shortness of breath, coughing, tightness in the throat, swelling of the face or neck

Tips for patients and families
- Discuss all questions with your doctor or pharmacist.
- Nexplanon is inserted in the doctor's office under local anesthesia; a pressure bandage is worn for 24 hours followed by a small bandage for 3–5 days.
- Confirm placement by feeling the implant with your doctor after insertion.
- The procedure may be scheduled during the first days of your period; a pregnancy test may be done before placement.
- Plan for removal at 3 years or sooner if pregnancy is desired or side effects occur; removal is similar to insertion.
- Call your doctor if you cannot feel the implant, think it is bent or broken, or suspect pregnancy.
- Tell your doctor about all medicines and OTC products, as some can reduce Nexplanon's effectiveness.
- Use backup contraception if the implant cannot be located and until confirmed in place.
- For pregnancy planning, fertility may return within 1–2 weeks after removal.
- Nexplanon does not protect against HIV or STDs; use condoms for protection.
