Indications & Clinical Uses

Nexplanon, a progestin hormonal contraceptive, is indicated for prevention of pregnancy.

  • Prevention of pregnancy: provides continuous contraception for up to three years.
  • Management of menstrual irregularities: may reduce frequency of heavy bleeding in some users.
  • Hormonal regulation: assists in stabilizing hormone levels for contraceptive purposes.

How It Works

  • Etonogestrel released from the Nexplanon implant binds to progesterone receptors in the hypothalamus and pituitary, suppressing the luteinizing hormone surge and thereby inhibiting ovulation. It also thickens cervical mucus, creating a barrier to sperm penetration, and induces endometrial changes that are unfavorable for implantation.

Side Effects

Common Side Effects

  • Irregular vaginal bleeding or spotting.
  • Amenorrhea (absence of periods).
  • Headache.
  • Acne or oily skin.
  • Weight gain.
  • Breast tenderness.

Serious or Rare Side Effects

  • Deep vein thrombosis or pulmonary embolism.
  • Severe allergic reaction (anaphylaxis).
  • Infection at the insertion site.
  • Ectopic pregnancy.
  • Hormonal hyperplasia.
  • Persistent severe abdominal pain.

Precautions & Warnings

Before insertion, a thorough medical assessment is required to identify contraindications and risk factors.

  • Pregnancy: contraindicated; category X – do not use in pregnant women.
  • Breastfeeding: not recommended during lactation.
  • Smoking: avoid use in women over 35 who smoke due to increased cardiovascular risk.
  • Medical history: assess for thromboembolic disorders, liver disease, or hormone‑sensitive cancers.
  • Drug interactions: review concomitant medications that may reduce contraceptive efficacy.
  • Store at below 25°C: keep in original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Etonogestrel may interact with several medications that affect its plasma concentration.

Major Interactions (Avoid)

  • Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin) – may reduce effectiveness.
  • Rifampin – decreases plasma levels of etonogestrel.
  • Certain antiretroviral protease inhibitors – may alter hormone metabolism.

Moderate Interactions (Monitor Closely)

  • Antifungal azoles (e.g., ketoconazole) – may increase hormone levels.
  • Broad‑spectrum antibiotics (e.g., ampicillin) – minimal effect but monitor for breakthrough bleeding.
  • Herbal supplements such as St. John's wort – may reduce contraceptive effectiveness.

Frequently Asked Questions

Nexplanon is a subcutaneous implant that provides long‑acting hormonal contraception. It is used to prevent pregnancy in women of reproductive age by delivering a steady dose of etonogestrel over several years.

Etonogestrel is a synthetic progestin that suppresses ovulation, thickens cervical mucus to block sperm entry, and alters the endometrium, creating conditions that are unfavorable for implantation.

The dose of Nexplanon is set by the prescribing healthcare professional. The implant contains a fixed amount of etonogestrel that provides contraceptive protection for up to three years.

Nexplanon is contraindicated in pregnancy (Category X) and should not be initiated in breastfeeding women. Women who become pregnant while using the implant should seek medical advice promptly.

Enquiries can be submitted on the product page at gnhindia.com with the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and import documentation.

Compared with oral contraceptives, Nexplanon offers continuous, user‑independent protection for up to three years, eliminating the need for daily dosing. It has a similar efficacy to other long‑acting reversible methods such as intrauterine devices but differs in insertion technique and side‑effect profile.

Nexplanon should be stored at temperatures below 25 °C, in its original sealed packaging, protected from moisture and direct sunlight. The implant must be handled by trained healthcare professionals using aseptic technique during insertion and removal.

A qualified healthcare provider inserts the Nexplanon implant subcutaneously in the inner side of the upper arm using a sterile applicator. The procedure is performed in an outpatient setting and takes only a few minutes.

Serious risks include deep vein thrombosis, pulmonary embolism, severe allergic reactions, infection at the insertion site, and ectopic pregnancy. Women should seek immediate medical attention if they experience symptoms such as unexplained leg swelling, chest pain, severe abdominal pain, or signs of an allergic reaction.

Nexplanon should not be used by women who are pregnant, have a known hypersensitivity to etonogestrel or any component of the implant, have active liver disease, a history of thromboembolic disorders, or are current smokers over the age of 35.
