Dienogest is used to reduce the painful symptoms of both endometriosis and the lesions. It decreases the amount of estrogen, a type of female hormones, and thus, slows the growth of the tissue outside the womb.
Endometriosis is a condition where tissue similar to the one lining the inside of the womb, known as the endometrium, can be found outside the womb itself or on other nearby organs such as the pelvic wall ovaries, bladder and bowel.
