Indications & Clinical Uses

  • Levonorgestrel is a progestin used in hormonal contraceptive pathways to prevent unintended pregnancy.
  • Emergency contraception: provides post‑coital protection to reduce the risk of pregnancy after unprotected intercourse.
  • Regular contraception: used as a progestin‑only oral method to inhibit ovulation and maintain contraceptive efficacy.
  • Ovulation suppression: blocks the luteinizing hormone surge, preventing follicular rupture and egg release.

How It Works

  • Levonorgestrel binds to progesterone receptors in the hypothalamus and pituitary, suppressing the mid‑cycle surge of luteinizing hormone and follicle‑stimulating hormone. This inhibition prevents follicular development and ovulation. In addition, the drug induces changes in cervical mucus, making it thicker and less permeable to sperm, and modifies the endometrial lining, reducing its receptivity to a fertilized ovum.

Side Effects

Levonorgestrel may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

  • Nausea: mild to moderate stomach upset.
  • Headache: transient cranial pain.
  • Breast tenderness: temporary discomfort.
  • Menstrual changes: spotting or altered bleeding patterns.

Serious or Rare Side Effects

  • Allergic reaction: rash, swelling, or anaphylaxis.
  • Blood clots: rare thromboembolic events.

Precautions & Warnings

  • Before prescribing Levonorgestrel, consider the following precautions to ensure safe use.
  • Pregnancy: contraindicated in known pregnancy; avoid use.
  • Liver disease: use with caution in patients with hepatic impairment.
  • Breast cancer: not recommended for women with active hormone‑sensitive breast cancer.
  • Hypersensitivity: discontinue if allergic reaction occurs.
  • Store at ambient temperature below 25°C: keep in original packaging, protect from moisture.

Avoid Interactions

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

Major Interactions (Avoid)

  • Rifampicin: enzyme inducer that reduces levonorgestrel levels.
  • St. John’s wort: herbal inducer decreasing effectiveness.
  • Anticonvulsants (phenytoin, carbamazepine): lower plasma concentrations.

Moderate Interactions (Monitor Closely)

  • Antifungals (ketoconazole, itraconazole): may increase levonorgestrel exposure.
  • Antiretrovirals (efavirenz, nevirapine): can alter hormone levels.
  • Antibiotics (rifampin, ampicillin): may modestly reduce efficacy.

Frequently Asked Questions

Levonorgestrel Stada is used as a hormonal contraceptive. It can be taken as emergency contraception after unprotected intercourse or as a regular daily tablet to prevent pregnancy when prescribed by a healthcare professional.

Levonorgestrel binds to progesterone receptors, suppresses the luteinizing hormone surge, and prevents ovulation. It also thickens cervical mucus and alters the uterine lining, making it less suitable for sperm penetration and implantation.

The dose is determined by the prescribing clinician based on the indication and individual patient factors. Patients should follow the healthcare provider’s instructions and not adjust the dose on their own.

Levonorgestrel is contraindicated in confirmed pregnancy and should not be used by women who are pregnant. Limited data exist for breastfeeding; clinicians usually advise caution and may recommend alternative contraceptive methods.

Submit an enquiry on the product page at gnhindia.com, specifying the required quantity.

Levonorgestrel offers a progestin‑only option with a well‑established safety profile and is effective when taken within 72 hours of intercourse. Some alternatives contain estrogen or have different time windows, which may affect suitability for certain patients.

Store the tablets at room temperature below 25 °C, in the original blister pack, protected from moisture and direct sunlight. Do not refrigerate or freeze the product.

Levonorgestrel Stada is taken orally. For emergency use it is usually a single tablet taken as soon as possible after unprotected sex. For ongoing contraception it is taken daily as directed by a healthcare professional.

Serious risks include severe allergic reactions such as anaphylaxis, rare thromboembolic events, and the possibility of ectopic pregnancy if fertilization occurs despite use. Seek immediate medical attention for severe abdominal pain, swelling, or signs of an allergic reaction.

Women who are known to be pregnant, have active hormone‑sensitive breast cancer, severe liver disease, or a documented hypersensitivity to levonorgestrel or any tablet excipients should avoid using this product.
