This medication is used by women to treat pelvic pain due to a certain disorder of the uterus (endometriosis - displaced tissue of the lining of the womb). Dienogest is a type of female hormone (progestin).
Dose
Tablet-taking can be started on any day of the menstrual cycle.
The dosage of Visanne is 1 tablet daily without any break, taken preferably at the same time each day with some liquid as needed. Tablets must be taken continuously without regard to vaginal bleeding. When a pack is finished, the next one should be started without interruption.
The efficacy of Visanne may be reduced in the event of missed tablets, vomiting and/or diarrhea (if occurring within 3-4 hrs after taking the tablet). In the event of missed tablet(s), the woman should take 1 tablet only as soon as she remembers and should then continue the next day to take the tablet at usual time. A tablet not absorbed due to vomiting or diarrhea should likewise be replaced by 1 tablet.
How it works
Dienogest acts on endometriosis by reducing the endogenous production of estradiol and thereby suppressing the trophic effects of estradiol on both the eutopic and ectopic endometrium. When given continuously, dienogest leads to a hypoestrogenic, hypergestagenic endocrine environment causing initial decidualization of endometrial tissue followed by atrophy of endometriotic lesions.
