Nexplanon may be associated with a range of adverse reactions, varying in frequency and severity.

Before prescribing Nexplanon, clinicians should consider several precautionary measures to ensure safe use. - Contraindications: active breast cancer, liver disease, or known thromboembolic disorders. - Pregnancy status: must be negative before insertion; product is contraindicated in pregnancy (Category X). - Smoking: avoid in women over 35 who smoke heavily due to increased cardiovascular risk. - Medication interactions: review concurrent use of enzyme‑inducing drugs that may reduce efficacy. - Follow‑up: schedule regular check‑ups to assess implant position and manage menstrual changes. - Store at ambient temperature: keep below 25 °C in original packaging, protect from moisture and direct sunlight.

Nexplanon can interact with other medicines that affect hormone metabolism or blood clotting.

Major Interactions (Avoid): - Enzyme inducers: carbamazepine, phenytoin, rifampin may lower etonogestrel levels, reducing contraceptive effectiveness. - Antifungal azoles: ketoconazole can increase hormone levels, potentially raising side‑effect risk.

Moderate Interactions (Monitor Closely): - Anticoagulants: warfarin may have altered INR; monitor coagulation parameters. - Antiretrovirals: certain protease inhibitors may affect hormone concentrations; adjust monitoring. - Herbal supplements: St. John’s wort may reduce efficacy; advise caution.
