Lesinelle (Drospirenone, Ethinylestradiol)

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

• Prevention of pregnancy: provides reliable contraceptive protection for women of childbearing potential.
• Hormonal contraception: used as part of a regimen to regulate menstrual cycles and provide cycle control.
• Management of menstrual disorders: may be prescribed to treat dysmenorrhea or irregular bleeding when combined oral contraceptives are appropriate.

• Drospirenone and ethinylestradiol act together to inhibit the mid‑cycle surge of luteinising hormone (LH) and follicle‑stimulating hormone (FSH), thereby suppressing ovulation. The estrogen component stabilises the endometrial lining, while the progestogenic component thickens cervical mucus and alters the endometrium, reducing the likelihood of fertilisation and implantation.

Adverse reactions may occur with any hormonal contraceptive. The following lists have been compiled from clinical data and post‑marketing experience.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: tension‑type or migraine‑like.
• Breast tenderness: transient swelling or discomfort.
• Mood changes: irritability or mild depressive symptoms.
• Weight gain: modest increase in body weight.
• Spotting: irregular breakthrough bleeding.

Serious or Rare Side Effects

• Venous thromboembolism: deep‑vein thrombosis or pulmonary embolism.
• Hypertension: new‑onset or worsening high blood pressure.
• Liver dysfunction: abnormal liver enzymes or cholestasis.
• Hyperkalemia: elevated serum potassium levels.
• Allergic reactions: rash, urticaria, or anaphylaxis.
• Vision changes: rare ocular disturbances.

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

• Cardiovascular risk assessment: avoid in patients with history of thromboembolic events.
• Blood pressure monitoring: check regularly, especially in hypertensive patients.
• Liver function evaluation: contraindicated in active liver disease.
• Smoking status: discourage use in women over 35 who smoke.
• Medication review: assess for interacting drugs that may affect efficacy.
• Store at ambient temperature: keep below 25 °C, retain in original packaging, protect from moisture and direct sunlight.

Lesinelle may interact with other medicines, altering its effectiveness or increasing adverse effects.

Major Interactions (Avoid)

• Antiepileptic enzymes inducers (e.g., carbamazepine, phenytoin): may reduce contraceptive efficacy.
• Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir): can increase hormone levels and risk of side effects.

Moderate Interactions (Monitor Closely)

• Antibiotics (e.g., rifampin): may modestly decrease effectiveness.
• Herbal supplements (e.g., St John's wort): potential reduction in contraceptive effect.
• Antifungal agents (e.g., fluconazole): may slightly increase hormone concentrations.
