Ovuloc LD Tablet contains Ethinyl Estradiol (0.02 mg) and Desogestrel (0.15 mg), a combined oral contraceptive indicated for the prevention of pregnancy. Ethinyl Estradiol is a synthetic estrogen, while Desogestrel is a third-generation progestin; together, they exert contraceptive effects primarily by inhibiting ovulation, altering cervical mucus to impede sperm penetration, and modifying the endometrial lining to prevent implantation. Ovuloc LD is administered orally, typically once daily at the same time each day, to maintain consistent hormone levels and optimize efficacy. It is suitable for women seeking reliable contraception and may also be prescribed for regulating menstrual cycles, reducing menstrual bleeding, and managing dysmenorrhea. Contraindications include known or suspected pregnancy, thromboembolic disorders, hormone-sensitive malignancies, liver dysfunction, and unexplained vaginal bleeding. Patients should be advised of potential side effects such as nausea, headache, breast tenderness, and mood changes. Careful assessment of individual risk factors, including cardiovascular history and smoking status, is essential before initiation. Ovuloc LD does not protect against sexually transmitted infections. Regular follow-up is recommended to monitor tolerance and adherence. This medication should be used under medical supervision to ensure safe and effective contraception.
