Indications & Clinical Uses

Norlevo, a progestin emergency contraceptive, works within the reproductive hormone pathway to prevent unintended pregnancy.

  • Emergency contraception (up to 72 hours after unprotected intercourse): reduces the risk of pregnancy when taken promptly.
  • Emergency contraception (up to 120 hours after unprotected intercourse): provides a later window for effective pregnancy prevention.
  • Post‑coital contraception: administered as a single dose to inhibit fertilisation after intercourse.

How It Works

  • Levonorgestrel binds to progesterone receptors in the hypothalamus and ovary, suppressing the luteinising hormone surge and thereby preventing or delaying ovulation. It may also impair fertilisation by altering tubal motility and reduce endometrial receptivity, decreasing the likelihood of implantation if fertilisation occurs.

Side Effects

Adverse reactions may occur with oral levonorgestrel emergency contraception.

Common Side Effects

  • Nausea
  • Abdominal pain or cramps
  • Fatigue or tiredness
  • Headache
  • Dizziness
  • Menstrual irregularities (early, delayed, or heavier bleeding)

Serious or Rare Side Effects

  • Allergic reactions including anaphylaxis
  • Severe abdominal pain or persistent vomiting
  • Unusual vaginal bleeding or spotting
  • Chest pain or shortness of breath
  • Thromboembolic events (deep‑vein thrombosis, pulmonary embolism)
  • Liver function abnormalities

Precautions & Warnings

Before using Norlevo, consider the following safety points.

  • Timing of administration: take as soon as possible after unprotected intercourse for maximum effectiveness.
  • Contraindications: do not use if known hypersensitivity to levonorgestrel or any tablet excipients.
  • Medical conditions: avoid if you have active liver disease, hormone‑dependent tumours, or unexplained vaginal bleeding.
  • Drug interactions: be aware of medications that may reduce efficacy, such as enzyme‑inducing agents.
  • Breastfeeding: consult a healthcare professional, as levonorgestrel passes into breast milk in small amounts.
  • Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Avoid Interactions

Levonorgestrel may interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

  • Rifampicin: induces metabolism and reduces contraceptive effectiveness.
  • Anticonvulsants (phenytoin, carbamazepine): lower plasma levonorgestrel levels.
  • St. John’s wort: may decrease drug exposure, compromising emergency contraception.

Moderate Interactions (Monitor Closely)

  • Hormonal contraceptives: concurrent use may reduce overall contraceptive reliability.
  • Antifungal azoles (ketoconazole): can increase levonorgestrel concentrations, raising side‑effect risk.
  • Protease inhibitor antiretrovirals: may alter levonorgestrel metabolism, requiring clinical monitoring.

Frequently Asked Questions

Norlevo is an oral emergency contraceptive containing levonorgestrel. It is intended for use after unprotected sexual intercourse to reduce the chance of an unintended pregnancy when taken within a defined time window.

Levonorgestrel acts by binding to progesterone receptors, suppressing the luteinising hormone surge and thereby preventing or delaying ovulation. It may also interfere with fertilisation and make the uterine lining less suitable for implantation.

The specific dose and regimen of Norlevo are determined by the prescribing healthcare professional. The product is supplied as a single‑dose tablet, and the prescriber will advise the appropriate administration based on timing of intercourse.

Norlevo is not intended for use during an established pregnancy. If pregnancy is confirmed, the product should not be taken. Small amounts of levonorgestrel can be excreted in breast milk; breastfeeding individuals should discuss use with a healthcare provider.

To order Norlevo, 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 any necessary import documentation.

Norlevo contains levonorgestrel, a progestin commonly used for emergency contraception. Compared with copper‑IUD insertion, it is less invasive but has a shorter efficacy window. Compared with ulipristal acetate, levonorgestrel may be slightly less effective after 72 hours but is widely available over the counter.

Store Norlevo tablets at ambient temperature below 25 °C, in the original packaging, and protect them from moisture and direct sunlight. Keep out of reach of children and do not use if the package is damaged.

Norlevo is taken orally as a single tablet. The tablet should be swallowed whole with water as soon as possible after unprotected intercourse, ideally within 72 hours, but it may be effective up to 120 hours depending on national guidelines.

Serious but rare risks include severe allergic reactions (anaphylaxis), persistent abdominal pain, unusual vaginal bleeding, and thromboembolic events such as deep‑vein thrombosis. Any signs of these conditions require immediate medical attention.

Norlevo should not be used by individuals with known hypersensitivity to levonorgestrel or any tablet ingredients, those who are already pregnant, or persons with active liver disease, hormone‑dependent tumours, or unexplained vaginal bleeding. Consultation with a healthcare professional is advised for any contraindications.
