Etonogestrel, a progestin hormonal contraceptive, is used to prevent pregnancy.

- Contraception: Provides effective prevention of pregnancy for up to three years after insertion of the subdermal implant. - Family planning: Enables long‑acting reversible contraception for women who prefer a non‑daily method. - Hormonal birth control: Delivers a steady release of progestin to inhibit ovulation without the need for daily dosing.

Common Side Effects: - Irregular bleeding or spotting: Changes in menstrual pattern are frequent during the first months. - Headache: Mild to moderate headaches may occur. - Weight gain: Some users report modest increases in body weight. - Breast tenderness: Mild discomfort or swelling of the breasts.

Serious or Rare Side Effects: - Ectopic pregnancy: Though rare, pregnancy may occur outside the uterus. - Implant migration: The rod may shift from its original insertion site. - Severe allergic reaction: Signs include rash, swelling, or difficulty breathing. - Infection at insertion site: Redness, warmth, or pus may develop. - Thrombosis: Rare clotting events have been reported.

Before insertion, clinicians should evaluate patient history and ensure appropriate use.

- Screen for contraindications: Confirm the patient is not pregnant and has no history of thromboembolic disorders. - Assess medical history: Review liver disease, hormone‑sensitive cancers, and severe migraines. - Monitor bleeding patterns: Counsel about possible changes in menstrual bleeding. - Avoid insertion in infection: Ensure the insertion site is clean and free of active infection. - Store at ambient temperature: Keep in the original packaging, protect from moisture and direct sunlight.

Etonogestrel may interact with other medicines that affect hormone metabolism or efficacy.

Major Interactions (Avoid): - Combined hormonal contraceptives: Do not use simultaneously as it may cause hormonal excess. - Enzyme inducers (e.g., rifampicin, carbamazepine): May reduce etonogestrel levels and effectiveness. - Antifungal azoles (e.g., ketoconazole): May increase etonogestrel concentrations, raising risk of side effects.

Moderate Interactions (Monitor Closely): - Certain antibiotics (e.g., tetracycline): May slightly lower contraceptive efficacy; monitor for breakthrough bleeding. - Herbal supplements (e.g., St. John’s wort): May decrease effectiveness; advise close observation.
