Indications & Clinical Uses

Levonorgestrel is a progestin used in hormonal contraception pathways.

  • Emergency contraception: prevents pregnancy after a single episode of unprotected intercourse.
  • Regular contraception: provides ongoing prevention of pregnancy when taken as directed.
  • Ovulation suppression: inhibits ovulation to reduce the chance of fertilization.

How It Works

  • Levonorgestrel binds to progesterone receptors in the hypothalamus and pituitary, suppressing the luteinizing hormone surge and thereby inhibiting ovulation. It also induces cervical mucus thickening and alters the endometrial lining, creating an environment unfavorable for sperm penetration and implantation.

Side Effects

Levonorgestrel may cause a range of adverse reactions.

Common Side Effects

  • Nausea: mild to moderate upset stomach.
  • Headache: transient tension-type headache.
  • Breast tenderness: temporary breast discomfort.
  • Irregular bleeding: spotting or changes in menstrual flow.
  • Abdominal pain: cramping or discomfort.
  • Fatigue: feeling unusually tired.

Serious or Rare Side Effects

  • Deep vein thrombosis: blood clot formation in deep veins.
  • Pulmonary embolism: clot traveling to lungs.
  • Severe allergic reaction: rash, swelling, or anaphylaxis.
  • Hepatic dysfunction: abnormal liver enzymes.
  • Ectopic pregnancy: implantation outside the uterus.

Precautions & Warnings

Before using Levonorgestrel, consider the following precautions.

  • Contraindications: avoid if history of thromboembolic disorders.
  • Liver health: assess for severe hepatic disease.
  • Medication review: check for interacting drugs.
  • Smoking: discourage use in women who smoke heavily.
  • Missed dose: follow prescriber guidance if a dose is omitted.
  • Store at room temperature: keep below 25°C in the original pack, protect from moisture.

Avoid Interactions

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

Major Interactions (Avoid)

  • Enzyme-inducing antiepileptics (e.g., phenytoin, carbamazepine): may reduce contraceptive effectiveness.
  • Rifampin: strong inducer that lowers levonorgestrel levels.
  • Griseofulvin: may decrease hormonal activity.

Moderate Interactions (Monitor Closely)

  • Azole antifungals (e.g., ketoconazole): can increase levonorgestrel concentrations.
  • Antiretrovirals (e.g., efavirenz): may lower effectiveness.
  • St. John’s Wort: herbal inducer that may reduce efficacy.
