Dydrogesterone is widely used in the treatment of various gynecological disorders. It is commonly prescribed to manage irregular menstrual cycles, providing hormonal balance to regulate periods. It is also effective in treating conditions like endometriosis by reducing abnormal tissue growth and alleviating associated pain. In cases of infertility due to luteal phase defects, dydrogesterone supports pregnancy by maintaining the uterine lining. Additionally, it is used in hormone replacement therapy (HRT) to counteract the effects of estrogen on the endometrium, reducing the risk of hyperplasia. During pregnancy, it is often administered to prevent miscarriage in women with a history of recurrent pregnancy loss by supporting progesterone levels. Its safety profile makes it a preferred choice for managing these conditions with minimal side effects.
