Marlies (Drospirenone, Ethinylestradiol | Lactose Anhydrous)

Marlies, a combined oral contraceptive, is indicated for hormonal contraception and related menstrual conditions.

• Contraception: Prevents pregnancy in women of childbearing potential.
• Menstrual cycle regulation: Helps achieve more regular and predictable menstrual bleeding.
• Acne improvement: May reduce acne associated with hormonal fluctuations.
• Endometriosis symptom relief: Can lessen dysmenorrhea and pelvic pain linked to endometriosis.

• Drospirenone/Ethinylestradiol works by binding to progesterone and estrogen receptors, suppressing the hypothalamic‑pituitary‑ovarian axis. This inhibition reduces the release of luteinizing hormone (LH) and follicle‑stimulating hormone (FSH), preventing follicular development and ovulation. In addition, the progestogenic component thickens cervical mucus and alters the endometrial lining, creating an environment unfavorable for sperm penetration and implantation.

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

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Breast tenderness: discomfort or swelling of the breasts.
• Headache: occasional throbbing or tension‑type pain.
• Spotting or breakthrough bleeding: irregular light bleeding between periods.
• Mood changes: irritability or mild mood swings.
• Weight gain: slight increase in body weight.

Serious or Rare Side Effects

• Venous thromboembolism: deep vein thrombosis or pulmonary embolism.
• Arterial thrombosis: stroke or myocardial infarction.
• Severe hypertension: sudden increase in blood pressure.
• Liver disorders: jaundice or hepatic dysfunction.
• Allergic reactions: rash, itching, or swelling.
• Severe depression or suicidal thoughts.

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

• Assess cardiovascular risk: review history of thromboembolic events, smoking, and hypertension.
• Screen for liver disease: avoid use in active liver dysfunction.
• Evaluate migraine history: contraindicated in migraine with aura.
• Counsel on smoking cessation: especially for women over 35 years.
• Review medication list: avoid concurrent use with strong enzyme inducers.
• Store at ambient temperature: keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Marlies can interact with several drug classes, affecting efficacy or safety.

Major Interactions (Avoid)

• Strong CYP3A4 inducers (e.g., rifampicin, carbamazepine): may markedly reduce contraceptive effectiveness.
• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Certain antiretrovirals (e.g., protease inhibitors): may alter hormone levels.

Moderate Interactions (Monitor Closely)

• Antiepileptic drugs (e.g., phenytoin, phenobarbital): may require additional contraceptive measures.
• Herbal supplements (e.g., St. John's wort): can decrease plasma hormone concentrations.
• Selective serotonin reuptake inhibitors (SSRIs): monitor for mood changes and rare serotonin syndrome.
