Leona (Ethinylestradiol, Levonorgestrel)

Leona, a combined oral contraceptive, is indicated for hormonal contraception to prevent pregnancy.

• Contraception: Prevents pregnancy by inhibiting ovulation and altering cervical mucus.
• Family planning: Provides reliable birth control for women seeking to avoid pregnancy.
• Prevention of pregnancy: Offers a reversible method of fertility control for women of child‑bearing potential.

• Leona combines an estrogen (ethinylestradiol) and a progestogen (levonorgestrel). The estrogen component suppresses follicle‑stimulating hormone, while the progestogen inhibits luteinizing hormone, together preventing ovulation. Additionally, the progestogen thickens cervical mucus and induces endometrial changes that reduce the likelihood of implantation.

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

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Breast tenderness: discomfort or swelling of the breasts.
• Headache: occasional throbbing pain.
• Spotting: irregular vaginal bleeding.
• Weight gain: slight increase in body weight.
• Mood changes: irritability or emotional fluctuations.

Serious or Rare Side Effects

• Venous thromboembolism: blood clots in deep veins or lungs.
• Hypertension: elevated blood pressure.
• Liver disorders: jaundice or hepatic dysfunction.
• Allergic reactions: rash, itching, or swelling.
• Visual disturbances: blurred vision or eye pain.
• Severe abdominal pain: may indicate serious abdominal conditions.

Before prescribing Leona, clinicians should evaluate individual risk factors and contraindications.

• Contraindications: Do not use in women with known thromboembolic disorders, active liver disease, or hormone‑dependent tumors.
• Smoking: Avoid in women over 35 who smoke, due to increased cardiovascular risk.
• Medical history: Review history of hypertension, diabetes, or migraines with aura.
• Medication review: Assess concomitant drugs that may affect estrogen metabolism.
• Pregnancy: Not for use during pregnancy (Category X).
• Store at ambient temperature: keep in the original pack, protect from moisture and heat.

Leona can interact with several medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

• Potent CYP3A4 inducers (e.g., rifampicin, carbamazepine): may markedly reduce contraceptive efficacy.
• Anticoagulants (e.g., warfarin): may increase clotting risk.

Moderate Interactions (Monitor Closely)

• Antifungals (e.g., ketoconazole): may increase hormone levels, raising side‑effect risk.
• Certain antibiotics (e.g., tetracycline): may slightly diminish contraceptive effectiveness.
• Herbal supplements (e.g., St. John's wort): may reduce plasma hormone concentrations.
