Marvelon

Desogestrel, the active ingredient in Marvelon, is a combined oral contraceptive presented as a desogestrel 150 µg / ethinylestradiol 30 µg tablet for oral use. It prevents pregnancy in women of reproductive age by inhibiting ovulation and altering cervical mucus.

GNH USA supplies Marvelon as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing consistent quality for global contraceptive needs and ensuring regulatory compliance across markets.

Marvelon, a combined oral contraceptive, is used to prevent pregnancy by regulating the hormonal cycle.

- Contraception: provides reliable protection against unintended pregnancy when taken as directed. - Menstrual cycle regulation: helps achieve regular withdrawal bleeding and reduces cycle variability. - Acne treatment: may improve mild to moderate acne associated with hormonal fluctuations.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Breast tenderness: temporary swelling or discomfort. - Headache: occasional tension‑type headaches. - Spotting: irregular light bleeding between periods. - Weight gain: slight increase in body weight. - Mood changes: mild emotional fluctuations.

Serious or Rare Side Effects: - Venous thromboembolism: blood clots in deep veins. - Arterial thrombosis: clot formation in arteries, potentially leading to stroke. - Hypertension: new or worsening high blood pressure. - Liver disorders: jaundice or hepatic dysfunction. - Severe allergic reaction: rash, swelling, or anaphylaxis. - Visual disturbances: sudden vision changes or loss.

Before initiating Marvelon, consider the following precautions: - Assess thrombotic risk: evaluate personal and family history of clotting disorders. - Screen for hypertension: measure blood pressure and manage elevated readings. - Avoid smoking: counsel women over 35 who smoke to discontinue use. - Review concomitant medications: identify drugs that may alter hormonal efficacy. - Pregnancy contraindication: do not use in confirmed or suspected pregnancy. - Store at ambient temperature: keep below 25 °C in the original pack, protect from moisture.

Marvelon may interact with several medicines that affect hormone metabolism.

Major Interactions (Avoid): - Strong CYP3A4 inducers (e.g., rifampicin, carbamazepine): may markedly reduce contraceptive effectiveness. - Protease inhibitors (e.g., ritonavir): can lower hormone levels, increasing failure risk. - St. John’s wort: may diminish plasma concentrations of estrogen and progestogen.

Moderate Interactions (Monitor Closely): - Antiepileptics (e.g., phenytoin, phenobarbital): may modestly decrease hormone exposure. - Antifungals (e.g., ketoconazole): can increase estrogen levels, raising side‑effect potential. - SSRIs (e.g., fluoxetine): may enhance mood‑related adverse effects and require observation.
