Oc 21 0.03/0.15 Mg Tablet 21 works through the synergistic action of two active ingredients:

Ethinyl Estradiol (0.03 mg): Ethinyl Estradiol is a synthetic estrogen that helps regulate hormonal levels in the body. It works by suppressing ovulation and stabilising the uterine lining to prevent pregnancy. Additionally, it reduces hormonal fluctuations that cause menstrual irregularities. This component also helps with acne control and hormone-related symptoms in some cases.
Levonorgestrel (0.15 mg): Levonorgestrel is a synthetic progestin that prevents ovulation and thickens cervical mucus to block sperm entry. It also alters the uterine lining, making it less favourable for egg implantation. This active ingredient is commonly used in combination with oral contraceptives for effective pregnancy prevention. Additionally, it can help manage heavy menstrual bleeding and hormonal imbalances.
