Levonille (Ethinylestradiol, Levonorgestrel | Lactose)

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

• Prevention of pregnancy: provides reliable contraceptive protection for women of childbearing potential.
• Menstrual cycle regulation: helps achieve more predictable menstrual bleeding patterns.
• Reduction of functional ovarian cysts: decreases the incidence of ovarian cyst formation.

• Levonille combines an estrogen (ethinylestradiol) and a progestogen (levonorgestrel) that bind to estrogen and progesterone receptors, suppressing the hypothalamic‑pituitary‑gonadal axis to inhibit the mid‑cycle LH surge, thereby preventing ovulation. The progestogen also thickens cervical mucus and the estrogen component stabilises the endometrial lining, reducing the likelihood of implantation.

Levonille may cause a range of adverse reactions. Patients should be aware of both common and serious possibilities.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Breast tenderness: temporary swelling or discomfort.
• Headache: occasional mild to moderate pain.
• Spotting or breakthrough bleeding: irregular light bleeding.

Serious or Rare Side Effects

• Deep vein thrombosis: blood clot formation in deep veins.
• Pulmonary embolism: clot migration to lung vessels.
• Stroke or myocardial infarction: rare cardiovascular events.
• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Hepatic adenoma: benign liver tumor.
• Vision changes: sudden visual disturbances.

Before prescribing Levonille, clinicians should evaluate individual risk factors and counsel patients on safe use.

• Assess thrombotic risk: review personal and family history of clotting disorders.
• Evaluate cardiovascular health: consider hypertension, smoking status, and age.
• Screen for hormone‑sensitive cancers: avoid in active breast or endometrial cancer.
• Review liver function: contraindicated in severe hepatic impairment.
• Counsel on smoking: advise cessation, especially for women over 35.
• Store below 25°C: keep in the original pack, protect from moisture.

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

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): reduce contraceptive efficacy.
• Rifampin or rifabutin: decrease hormone levels, increasing risk of pregnancy.
• Protease inhibitors (e.g., ritonavir): may cause unpredictable hormone concentrations.
• St. John’s wort: herbal inducer that lowers contraceptive effectiveness.

Moderate Interactions (Monitor Closely)

• Certain antibiotics (e.g., tetracycline, metronidazole): possible reduced absorption.
• Antifungal agents (e.g., ketoconazole, itraconazole): may increase hormone levels, raising side‑effect risk.
• Diuretics (e.g., thiazides): can affect fluid balance and blood pressure.
