Dinogestrel can be taken until menopause. The new progestin Dinogestrel is currently used to treat endometriosis cysts and adenomyosis. When treating endometriosis, Dinogestrel not only relieves menstrual cramps, but also shrinks ovarian endometriosis cysts at the same time, and the longer the medication is used, the more pronounced is the effect of shrinking the ectopic cysts. Progesterone can relieve dysmenorrhea and reduce menstrual flow when treating adenomyosis. Dinogestrel inhibits the secretion of gonadotropins through negative feedback, resulting in a low estrogen state in the body, inhibiting endometrial hyperplasia, inhibiting inflammatory responses in the endometrium, and inhibiting blood vessel formation. Due to its low daily oral dose, it also has little effect on renal function, hepatic function and metabolism, and is well tolerated, and there is sufficient evidence for the effectiveness and safety of long-term application for more than one year. Common side effects of Dienogest are mainly irregular uterine bleeding, but also include weight gain, headache, and breast tenderness. It is recommended to use the drug under the guidance of a gynecologist, and to seek medical advice if there is any discomfort during the course of taking the drug.
