What should you know about Nexplanon etonogestrel?

Etonogestrel is a progestogen. The flexible rod sits under the skin of the upper arm and steadily releases the hormone. It mainly prevents ovulation and also changes cervical mucus, making it harder for sperm to reach an egg. It does not protect against sexually transmitted infections.

Bleeding may become less predictable after insertion. Some people have spotting, longer bleeding, more frequent bleeding, or no bleeding. These changes do not by themselves show whether the implant is working, but troublesome bleeding deserves a clinical discussion.

Tell the clinician about pregnancy possibility, medicines, supplements, allergies, liver problems, and any history of breast-related disease. Some medicines can reduce hormonal contraceptive effectiveness, so provide a complete list rather than relying on memory.

Keep the insertion dressing and follow the clinic's wound-care instructions. Once healed, avoid repeatedly pressing or manipulating the rod. Arrange removal or replacement with a trained clinician; do not attempt either at home. If you cannot feel the rod, use another contraceptive method and contact the clinic for advice.

Contact a clinician promptly for increasing pain, spreading redness, warmth, swelling, pus, fever, persistent numbness, or weakness in the arm. Seek urgent help for severe lower abdominal pain, fainting, or a positive pregnancy test with pain or bleeding. These symptoms need assessment and are not explained simply by common bleeding changes.

Ask when pregnancy protection starts for your situation, which medicines may interfere, what bleeding pattern to expect, how the rod will be checked, and what contraceptive option would suit you if you prefer a device placed in the uterus.
