Indications & Clinical Uses

Norlevo (levonorgestrel) is used as an emergency contraceptive to intervene in the reproductive hormone pathway after unprotected intercourse.

  • Unprotected intercourse: reduces the chance of pregnancy when taken promptly after exposure.
  • Contraceptive failure: provides backup protection after a missed oral contraceptive pill.
  • Sexual assault: offers an immediate option for emergency pregnancy prevention.

How It Works

  • Levonorgestrel binds to progesterone receptors in the hypothalamus and ovary, inhibiting or delaying the luteinizing hormone surge that triggers ovulation. By preventing ovulation, it reduces the likelihood of fertilization. If ovulation has already occurred, the drug may impair sperm transport or fertilization and may also alter the endometrial lining, potentially inhibiting implantation of a fertilized egg.

Side Effects

Norlevo may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

  • Nausea: mild to moderate upset stomach.
  • Abdominal pain: cramping or discomfort in the lower abdomen.
  • Headache: occasional tension‑type headache.
  • Dizziness: feeling light‑headed or unsteady.
  • Fatigue: temporary tiredness.
  • Menstrual changes: spotting or alteration of cycle timing.

Serious or Rare Side Effects

  • Allergic reaction: rash, itching, swelling, or difficulty breathing.
  • Severe abdominal pain: persistent or worsening pain.
  • Chest pain: unexplained tightness or pressure.
  • Severe vomiting: inability to retain fluids.
  • Liver dysfunction: jaundice or abnormal liver tests (very rare).

Precautions & Warnings

Before using Norlevo, consider the following safety measures.

  • Timing of intake: take the tablet as soon as possible, ideally within 72 hours after intercourse.
  • Contraindications: avoid if you have a known hypersensitivity to levonorgestrel or any tablet excipients.
  • Pregnancy status: do not use if you are already pregnant; consult a healthcare professional if you suspect pregnancy.
  • Medical conditions: caution in women with active liver disease, uncontrolled epilepsy, or severe hormonal disorders.
  • Drug interactions: be aware that enzyme‑inducing medicines may lower effectiveness.
  • Store at ambient temperature: keep in the original pack, protect from moisture and heat, and store below 25 °C.

Avoid Interactions

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

Major Interactions (Avoid)

  • Rifampicin: strong enzyme inducer that can markedly reduce levonorgestrel effectiveness.
  • St. John’s wort: herbal inducer that may lower drug levels.
  • Anticonvulsants (phenytoin, carbamazepine): can decrease contraceptive efficacy.

Moderate Interactions (Monitor Closely)

  • Antifungal azoles (ketoconazole, itraconazole): may increase levonorgestrel concentrations.
  • Hormonal contraceptives: concurrent use may lead to additive hormonal effects.
  • Certain antibiotics (e.g., ampicillin): potential but uncertain impact on efficacy.

Frequently Asked Questions

Norlevo is an oral tablet containing levonorgestrel that is used as an emergency contraceptive. It is intended to be taken after unprotected sexual intercourse or contraceptive failure to reduce the risk of an unintended pregnancy. The product is available over the counter in many European markets.

Levonorgestrel works by binding to progesterone receptors, which inhibits or delays the surge of luteinizing hormone that triggers ovulation. By preventing ovulation, it reduces the chance of fertilization. If ovulation has already occurred, the drug may also interfere with sperm transport, fertilization, or implantation of a fertilized egg.

The specific dosing regimen for Norlevo is determined by the prescribing healthcare professional or the product labeling. Typically, a single tablet is taken as directed, but the exact dose and timing should follow the instructions provided by the prescriber or the package insert.

Norlevo is intended for use before pregnancy occurs and is not meant for ongoing use during an established pregnancy. If you become pregnant after taking the tablet, you should contact a healthcare provider. Limited data are available for breastfeeding, and a clinician should be consulted to weigh potential risks and benefits.

To order Norlevo, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies, and procurement teams worldwide. After submission, the sales team will verify trade or institutional credentials, then provide pricing, availability, shipping details, and any necessary import documentation.

Norlevo contains levonorgestrel, which is a progestogen‑based emergency contraceptive. Alternative options include ulipristal acetate, a selective progesterone receptor modulator, and the copper IUD. Levonorgestrel is generally effective when taken within 72 hours, while ulipristal may be effective up to 120 hours and the copper IUD provides the longest post‑coital protection.

Norlevo tablets should be stored at ambient temperature, below 25 °C. Keep them in the original packaging to protect from moisture and direct sunlight. Do not store in bathrooms or near heat sources. Ensure the container is tightly closed to maintain tablet integrity.

Norlevo is taken orally as a single tablet. The tablet should be swallowed whole with water, preferably as soon as possible after unprotected intercourse. No food restrictions are required, but taking the tablet with a glass of water can aid absorption.

Serious but rare risks include severe allergic reactions such as rash, swelling, or difficulty breathing, and severe abdominal or chest pain that may indicate a more serious condition. If any of these symptoms occur, seek immediate medical attention. Persistent vomiting or signs of liver dysfunction also warrant prompt evaluation.

Norlevo should not be used by individuals with a known hypersensitivity to levonorgestrel or any tablet excipients. It is also contraindicated in women who are already pregnant. Women with severe liver disease, uncontrolled epilepsy, or certain hormonal disorders should consult a healthcare professional before use.
