Liana (Ethinylestradiol, Levonorgestrel)

• Liana, a combined oral contraceptive, is used to prevent pregnancy by modulating the hormonal axis.
• Contraception: Prevents pregnancy by suppressing ovulation and altering cervical mucus.
• Menstrual cycle regulation: Helps establish regular menstrual bleeding patterns.
• Acne treatment: Reduces androgen‑driven acne in women when prescribed for this indication.

• Ethinylestradiol and levonorgestrel act synergistically to inhibit the hypothalamic‑pituitary‑ovarian axis, reducing the secretion of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH). This suppression prevents follicular development and ovulation. In addition, the progestogenic component thickens cervical mucus and the estrogen component stabilizes the endometrial lining, creating an environment unfavorable for implantation.

Liana 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.
• Headache: tension‑type or migraine‑like pain.
• Breast tenderness: discomfort or swelling of the breasts.
• Spotting or breakthrough bleeding: irregular light bleeding.
• Weight change: slight increase or decrease.
• Mood swings: emotional variability.

Serious or Rare Side Effects

• Venous thromboembolism: blood clots in deep veins.
• Pulmonary embolism: clot migration to lungs.
• Stroke or transient ischemic attack.
• Myocardial infarction: heart attack risk.
• Severe allergic reaction: rash, swelling, anaphylaxis.
• Liver dysfunction: jaundice or abnormal liver enzymes.

• Before prescribing Liana, clinicians should evaluate individual risk factors and contraindications.
• Assess cardiovascular risk: avoid in women with history of thromboembolic disease.
• Screen for smoking status: contraindicated in smokers over 35 years.
• Avoid use in pregnancy: product is classified as pregnancy category X.
• Consider hepatic function: liver disease may alter drug metabolism.
• Monitor blood pressure regularly during therapy.
• Store at ambient temperature: keep in the original pack, protect from moisture.

Liana can interact with several medicines, affecting efficacy or safety.

Major Interactions (Avoid)

• Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): markedly reduce contraceptive effectiveness.
• Rifampin: decreases hormone levels, increasing risk of unintended pregnancy.
• Certain HIV protease inhibitors (e.g., ritonavir): may heighten risk of thrombotic events.

Moderate Interactions (Monitor Closely)

• Broad‑spectrum antibiotics (e.g., tetracycline): may slightly diminish contraceptive reliability.
• St. John’s Wort: herbal inducer that can lower hormone concentrations.
• Selective serotonin reuptake inhibitors (e.g., fluoxetine): may increase hormone exposure, requiring monitoring.
