Hamsini 30 Tablet is a combined oral contraceptive containing Ethinyl Estradiol (0.03 mg) and Drospirenone (3 mg), indicated for the prevention of pregnancy. Ethinyl Estradiol is a synthetic estrogen, while Drospirenone is a synthetic progestin with anti-mineralocorticoid and anti-androgenic properties. This combination works primarily by inhibiting ovulation, altering the cervical mucus to prevent sperm penetration, and modifying the endometrial lining to reduce the likelihood of implantation. Hamsini 30 is typically administered once daily, preferably at the same time each day, to maintain consistent hormone levels and optimize contraceptive efficacy. It is important to initiate therapy on the first day of the menstrual cycle or as advised by a healthcare professional. Besides contraception, this medication may also be used to regulate menstrual cycles, reduce menstrual cramps, and manage acne in women of reproductive age. Contraindications include known or suspected pregnancy, history of thromboembolic disorders, hormone-sensitive malignancies, uncontrolled hypertension, and liver dysfunction. Patients should be advised about potential side effects such as nausea, headache, breast tenderness, and mood changes. Regular medical follow-up is recommended to monitor tolerance and address any adverse effects. Hamsini 30 should be used under medical supervision to ensure safe and effective use.
