Levorichter 30 (Ethinylestradiol, Levonorgestrel)

Levorichter 30, a combined oral contraceptive, is indicated for hormonal contraception and related menstrual disorders.

• Contraception: prevents pregnancy in women of childbearing potential.
• Menstrual cycle regulation: helps achieve more regular menstrual periods.
• Acne management: may improve acne associated with hormonal fluctuations.

• Ethinylestradiol and levonorgestrel act together to suppress the hypothalamic‑pituitary‑ovarian axis. Ethinylestradiol provides estrogenic activity that stabilises the endometrium, while levonorgestrel, a progestogen, inhibits the mid‑cycle luteinising hormone surge, preventing ovulation, thickens cervical mucus and alters the endometrial lining to reduce the chance of implantation.

Levorichter 30 may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea or vomiting.
• Breast tenderness or enlargement.
• Headache or migraine.

Before prescribing Levorichter 30, clinicians should evaluate patient history and risk factors.

Levorichter 30 can interact with several medicines that affect its efficacy or safety.

Major Interactions (Avoid)

• Anticonvulsants (e.g., carbamazepine, phenytoin): may reduce contraceptive effectiveness.
• Rifampicin or other potent enzyme inducers: can markedly lower hormone levels.
• Certain antiretrovirals (e.g., efavirenz): may compromise contraceptive reliability.

Moderate Interactions (Monitor Closely):\n- Antibiotics (e.g., tetracycline, metronidazole): may slightly decrease hormone levels.

• Herbal supplements containing St. John's wort: potential reduction in efficacy.
• Antifungal agents (e.g., fluconazole): may increase hormone concentrations, requiring monitoring.
