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 tablet taking). 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 her usual time. A tablet not absorbed due to vomiting or diarrhea should likewise be replaced by 1 tablet.
Renal Impairment: There are no data suggesting the need for a dosage adjustment in patients with renal impairment.
