Levonorgestrel/Ethinylestradiol Biogaran (Ethinylestradiol, Levonorgestrel)

Levonorgestrel/Ethinylestradiol is a combined oral contraceptive used to prevent pregnancy.

• Prevention of pregnancy: provides reliable hormonal contraception for women of reproductive age.
• Menstrual cycle regulation: helps achieve more predictable bleeding patterns and may reduce menstrual discomfort.
• Treatment of hormonal acne: can improve skin condition by stabilizing androgen‑related fluctuations.

• Levonorgestrel/Ethinylestradiol combines an estrogen (ethinylestradiol) and a progestogen (levonorgestrel). Ethinylestradiol suppresses follicle‑stimulating hormone, inhibiting follicular development, while levonorgestrel blocks the luteinizing hormone surge, preventing ovulation. The progestogen also thickens cervical mucus and alters the endometrial lining, creating an environment unsuitable for sperm penetration and implantation.

Levonorgestrel/Ethinylestradiol may cause a range of adverse reactions.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: tension‑type or migraine‑like pain.
• Breast tenderness: swelling or discomfort of the breasts.
• Irregular bleeding: spotting or breakthrough bleeding between periods.

Serious or Rare Side Effects

• Deep vein thrombosis: blood clot formation in deep veins.
• Pulmonary embolism: clot migration to lung arteries.
• Severe allergic reaction: hives, swelling, or anaphylaxis requiring urgent care.

Before prescribing Levonorgestrel/Ethinylestradiol, clinicians should consider several safety factors.

• Assess thrombotic risk: evaluate personal and family history of clotting disorders.
• Screen for hypertension: monitor blood pressure prior to initiation.
• Review smoking status: avoid use in women >35 years who smoke.
• Consider liver function: contraindicated in severe hepatic impairment.
• Avoid in pregnancy: contraindicated during known or suspected pregnancy.
• Store at ambient temperature: keep below 25 °C, protect from moisture and light in original packaging.

Levonorgestrel/Ethinylestradiol can interact with other medicines, affecting its effectiveness or safety.

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): reduce contraceptive efficacy.
• Rifampin or griseofulvin: may decrease hormone levels.
• Certain protease inhibitors (e.g., ritonavir): alter hormone metabolism.

Moderate Interactions (Monitor Closely)

• St. John’s wort: may lower effectiveness, monitor menstrual pattern.
• SSRIs: potential increase in mood‑related side effects.
• Diuretics (e.g., spironolactone): may affect fluid balance and blood pressure.
