Madeleine (Drospirenone, Ethinylestradiol)

Madeleine, a combined oral contraceptive, is indicated for contraception, a hormonal pathway that prevents pregnancy.

• Pregnancy prevention: provides reliable contraception for women of childbearing potential.
• Moderate acne treatment: reduces acne lesions by regulating hormonal influence on the skin.
• Premenstrual dysphoric disorder (PMDD) management: alleviates emotional and physical symptoms associated with the menstrual cycle.

• Drospirenone/Ethinylestradiol binds to progesterone and estrogen receptors, suppressing the hypothalamic‑pituitary‑ovarian axis. This inhibition reduces the secretion of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH), preventing follicular development and ovulation. Concurrently, the estrogen component stabilizes the endometrial lining, while the progestin component thickens cervical mucus, creating a hostile environment for sperm penetration and implantation.

Common Side Effects

• Nausea: mild to moderate stomach upset, often transient.
• Breast tenderness: swelling or discomfort in the breast tissue.
• Headache: varying intensity, may improve with continued use.
• Breakthrough bleeding: spotting between periods, especially during the first cycles.
• Weight gain: modest fluid retention or appetite changes.
• Mood changes: irritability or mild mood swings.

Serious or Rare Side Effects

• Venous thromboembolism: deep vein thrombosis or pulmonary embolism, requiring immediate medical attention.
• Arterial thrombosis: stroke or myocardial infarction, particularly in high‑risk individuals.
• Severe hypertension: sudden increase in blood pressure, potentially leading to organ damage.
• Liver disorders: jaundice or hepatic dysfunction.
• Severe allergic reactions: rash, swelling, or anaphylaxis.

Before starting Madeleine, consider the following precautions:

• Contraindication: history of venous or arterial thromboembolism, or known clotting disorders.
• Pregnancy: not to be used during pregnancy; effective contraception is required.
• Smoking: avoid if over 35 years old and smoking more than 15 cigarettes per day.
• Liver disease: use with caution in severe hepatic impairment.
• Migraine with aura: contraindicated due to increased stroke risk.
• Store at ambient temperature: keep below 25 °C, retain in the original packaging, and protect from moisture.

Madeleine may interact with other medicines as follows:

Major Interactions (Avoid)

• Strong CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort): may markedly reduce contraceptive effectiveness.
• Potent antifungal agents (e.g., ketoconazole, itraconazole): can increase hormone levels, raising the risk of adverse effects.

Moderate Interactions (Monitor Closely)

• Certain antibiotics (e.g., macrolides, tetracyclines): may slightly lower efficacy; monitor for breakthrough bleeding.
• Selective serotonin reuptake inhibitors (SSRIs): potential for increased bleeding tendency.
• Antihypertensives (e.g., beta‑blockers, ACE inhibitors): may require blood‑pressure monitoring due to possible interaction.
