How often should the Xulane patch be changed?

The Xulane patch is a hormonal contraceptive method that is applied to the skin to prevent pregnancy. It is designed to be changed weekly, specifically every seven days. However, it is important to recognize that while the patch is applied for three-week intervals, a new patch must be applied on the same day of the week each week. This means that during the fourth week, no patch is worn, allowing for a withdrawal bleed similar to a menstrual period.

The key aspect here is that each patch is intended to be used for a week, but because it is part of a three-week regimen with a patch-free week, it is important to understand that the patch itself is changed weekly. This is why the correct answer aligns with the biweekly structured regimen of applying a new patch every week for three consecutive weeks.
