Indications & Clinical Uses

Etonogestrel, a progestin contraceptive, is indicated for prevention of pregnancy.

  • Contraception: provides long‑acting reversible birth control for up to three years.
  • Family planning: enables women to avoid unintended pregnancy without daily dosing.
  • Prevention of pregnancy: offers a single‑procedure method with high efficacy.

How It Works

  • Etonogestrel binds to progesterone receptors in the hypothalamus and pituitary, suppressing the luteinizing hormone surge and thereby inhibiting ovulation. It also thickens cervical mucus to impede sperm penetration and induces endometrial changes that reduce the likelihood of implantation.

Side Effects

Common Side Effects

  • Irregular vaginal bleeding or amenorrhea.
  • Headache.
  • Acne or oily skin.
  • Weight gain.
  • Insertion‑site pain or bruising.
  • Mood changes.

Serious or Rare Side Effects

  • Infection at the implant site.
  • Deep vein thrombosis or pulmonary embolism.
  • Severe allergic reaction (anaphylaxis).
  • Ectopic pregnancy if contraceptive failure occurs.
  • Implant migration or extrusion.

Precautions & Warnings

Before using Implanon Nxt, consider the following precautions.

  • Medical evaluation: confirm no contraindications such as active thromboembolic disorders.
  • Medication review: assess for drugs that may reduce contraceptive effectiveness.
  • Pregnancy testing: ensure the patient is not pregnant prior to insertion.
  • Follow‑up: schedule a post‑insertion visit to verify proper placement.
  • Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Etonogestrel may interact with other medicines; review the following.

Major Interactions (Avoid)

  • Rifampin: enzyme inducer that can lower etonogestrel levels.
  • Carbamazepine: may reduce contraceptive efficacy.
  • Phenytoin: can decrease hormone concentrations.
  • St. John’s wort: herbal inducer that may compromise effectiveness.
  • Anticonvulsants (e.g., phenobarbital): risk of reduced protection.

Moderate Interactions (Monitor Closely)

  • Azole antifungals (e.g., ketoconazole): may increase hormone levels.
  • HIV protease inhibitors: potential elevation of etonogestrel concentrations.

Frequently Asked Questions

Implanon Nxt is a subdermal implant that provides long‑acting reversible contraception. It is used to prevent pregnancy in women of reproductive age for up to three years after a single insertion procedure.

Etonogestrel, the hormone released from the implant, suppresses the luteinizing hormone surge, which stops ovulation. It also thickens cervical mucus, making it difficult for sperm to reach an egg, and alters the uterine lining to reduce the chance of implantation.

The implant contains a fixed 68 mg dose of etonogestrel. The prescribing healthcare professional determines the appropriate use and insertion timing; no daily dosing is required after placement.

Implanon Nxt is intended for use in women who are not pregnant. If pregnancy occurs, the implant should be removed. Limited data exist for breastfeeding, and a clinician should evaluate the benefits and risks before use.

Submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and import documentation.

Compared with daily oral contraceptives, Implanon Nxt offers continuous protection without the need for daily adherence, reducing user error. It provides similar efficacy to other hormonal implants but differs from intrauterine devices in placement technique and hormone type.

Store the implant at ambient temperature, below 25 °C, in its original sealed packaging. Protect it from moisture, direct sunlight and extreme temperatures to maintain product integrity until insertion.

A qualified healthcare professional inserts the 68 mg etonogestrel implant subdermally, typically in the inner side of the upper arm, using a sterile applicator. The procedure is performed in a clinical setting under aseptic conditions.

Serious risks include infection at the insertion site, deep vein thrombosis or pulmonary embolism, severe allergic reactions, and rare cases of ectopic pregnancy if contraceptive failure occurs. Prompt medical attention is required if any of these events are suspected.

Women with active thromboembolic disorders, known or suspected breast cancer, liver disease, or those who are pregnant should avoid Implanon Nxt. Additionally, individuals taking strong enzyme‑inducing medications that may reduce efficacy should discuss alternatives with their clinician.
