Maitalon (Drospirenone, Ethinylestradiol)

• Maitalon, a combined oral contraceptive, is used within the hormonal contraception pathway to prevent pregnancy.
• Contraception (prevention of pregnancy): Provides reliable inhibition of ovulation and prevents fertilization.
• Family planning: Enables women to plan pregnancies according to personal goals.
• Menstrual regulation: Helps maintain regular menstrual cycles in many users.
• Acne improvement: May reduce androgen‑related acne as a secondary benefit in some patients.

• Drospirenone and ethinylestradiol act together to suppress the hypothalamic‑pituitary‑ovarian axis. Drospirenone, a progestogenic agent with anti‑mineralocorticoid activity, blocks luteinizing hormone (LH) and follicle‑stimulating hormone (FSH) release, preventing ovulation. Ethinylestradiol, a synthetic estrogen, stabilises the endometrial lining and enhances cervical mucus viscosity, creating an environment hostile to sperm penetration and implantation.

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

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Headache: tension‑type or migraine‑like pain.
• Breast tenderness: temporary swelling or discomfort.
• Weight gain: modest increase in body weight.
• Mood changes: irritability or emotional fluctuations.
• Spotting or breakthrough bleeding: irregular bleeding between periods.

Serious or Rare Side Effects

• Venous thromboembolism: deep‑vein thrombosis or pulmonary embolism.
• Arterial thrombosis: stroke or myocardial infarction.
• Hypertension: new‑onset or worsening high blood pressure.
• Liver disorders: cholestasis or hepatic dysfunction.
• Severe allergic reaction: anaphylaxis, angioedema, or rash.
• Visual disturbances: sudden loss of vision or eye pain.

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

• Assess cardiovascular risk: review history of thrombosis, smoking, hypertension, or obesity.
• Avoid use in smokers over 35 years: smoking markedly increases thrombotic risk.
• Consider liver function: monitor patients with hepatic disease or elevated liver enzymes.
• Monitor blood pressure: watch for new or worsening hypertension during therapy.
• Review concomitant medications: check for drugs that may alter hormonal efficacy.
• Store at ambient temperature: keep in the original pack, protect from moisture and light.

Maitalon can interact with several medicines that affect hormone metabolism or clotting pathways.

Major Interactions (Avoid)

• Antiepileptic enzyme inducers (e.g., carbamazepine, phenytoin): reduce contraceptive effectiveness.
• Rifampin or griseofulvin: may lower plasma hormone levels.
• Certain antiretrovirals (protease inhibitors): alter hormone metabolism.

Moderate Interactions (Monitor Closely)

• St. John’s wort: may decrease contraceptive efficacy.
• Ketoconazole and other strong antifungals: can increase hormone concentrations.
• Diuretics (especially potassium‑sparing): may affect drospirenone’s anti‑mineralocorticoid activity.
