Ortho Evra 21 Day is applied to clean, dry skin on the abdomen, buttocks, upper torso (excluding breasts), or outer arm. Each patch should be worn continuously for 7 days before being replaced with a new patch. The patch needs to be changed once a week, on the same day. Remove the old patch before applying a new one to a different area of skin to prevent irritation. After 3 weeks (21 days), the patch should be removed for a patch-free week. A new cycle of patches should begin on the same day of the week that the previous cycle was started.
Avoid cutting or damaging it, and only apply it to clean, dry skin on areas of the body where tight clothing will not rub against it. It should not be placed on breasts or irritated skin. Additionally, do not use any lotions, creams, oils, powders, or makeup on the patch site, as this may cause it to loosen or fall off.
If a patch is missed or comes off, it should be replaced as soon as possible. If the patch has been off for more than 24 hours, a backup method of contraception should be used for the next 7 days.
