Levina (Ethinylestradiol, Levonorgestrel)

Levina, a combined oral contraceptive, acts on the hypothalamic‑pituitary‑ovarian axis to prevent pregnancy and manage menstrual disorders.

• Contraception: prevents pregnancy by inhibiting ovulation and altering cervical mucus.
• Menstrual cycle regulation: helps establish regular menstrual bleeding and reduces dysmenorrhea.
• Acne treatment in women: improves acne by reducing androgenic activity associated with hormonal fluctuations.

• Ethinylestradiol and levonorgestrel bind to estrogen and progesterone receptors, respectively, suppressing the mid‑cycle surge of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH). This inhibition prevents ovulation, while the progestogenic component thickens cervical mucus and induces endometrial changes that reduce the likelihood of implantation.

Like all hormonal contraceptives, Levina may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: tension‑type or migraine‑like pain.
• Breast tenderness: temporary swelling or discomfort.
• Spotting or irregular bleeding: especially during the first months of use.
• Mood changes: irritability or mild depressive symptoms.
• Weight gain: modest increase in body weight.

Serious or Rare Side Effects

• Deep vein thrombosis: blood clot formation in deep veins.
• Pulmonary embolism: clot migration to lung vessels.
• Stroke: cerebrovascular accident due to clot or hemorrhage.
• Myocardial infarction: heart attack risk in susceptible individuals.
• Severe allergic reaction (anaphylaxis): rare but potentially life‑threatening.
• Liver tumor: very rare hepatic neoplasm.

Before prescribing Levina, clinicians should consider several safety precautions to minimize risks.

• Smoking status: avoid use in women over 35 who smoke due to increased cardiovascular risk.
• Cardiovascular history: contraindicated in patients with a history of thromboembolic disorders, stroke, or myocardial infarction.
• Liver disease: use with caution in active liver disease or hepatic tumors.
• Migraine with aura: avoid in women who experience migraine with aura.
• Medication interactions: review concomitant drugs that may affect hormone metabolism.
• Store at ambient temperature: keep below 25 °C, in original packaging, protected from moisture and light.

Levina can interact with other medicines, altering its effectiveness or increasing adverse effects.

Major Interactions (Avoid)

• Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin, rifampicin): markedly reduce contraceptive efficacy.
• Certain antibiotics (e.g., griseofulvin): may decrease hormone levels, risking breakthrough bleeding.
• HIV protease inhibitors (e.g., ritonavir): can increase hormone concentrations, raising risk of side effects.

Moderate Interactions (Monitor Closely)

• St. John’s wort: may lower efficacy; monitor for breakthrough bleeding.
• Antifungal azoles (e.g., ketoconazole): may increase hormone levels; watch for increased side effects.
• Diuretics (e.g., spironolactone): may enhance anti‑androgenic effects; monitor clinical response.
