It contains a combination of female hormones that prevent ovulation and change the lining of the uterus, making it difficult for a fertilized egg to implant. It also contributes to making cervical mucus thicker, which prevents sperm from reaching the egg. It is also used to treat some hormonal problems such as acne and polycystic ovary syndrome. It should be taken daily at the same time, while adhering to medical instructions and not stopping it without consulting a doctor to avoid menstrual irregularities or reducing its effectiveness. Therefore, Dian 35 is one of the effective pills for contraception and regulating hormones in women.
