Ovarian chocolate cysts that don’t go away with dinogestrel tablets, although dinogestrel tablets can be used to treat endometriosis. Dinogestrel is a progestin drug that is used clinically to treat endometriosis. If endometriosis causes symptoms such as increased menstrual flow, prolonged periods, and menstrual cramps, you can take Dinogestrel tablets under doctor’s supervision. An ovarian chocolate cyst is a cyst caused by endometriosis that has ectopically displaced the endometrium to the ovary. However, if a cyst has already formed, taking Dinogestrel will not make it disappear, but will only reduce or slow down the growth of the cyst. If the chocolate cyst is relatively small, dinogestrel can be used under the supervision of a doctor, mainly to inhibit the growth of the cyst. However, if the cyst is over 5 centimeters in size, surgery is recommended as soon as possible because complications such as torsion or rupture may occur.
