WHAT IS IT?
The hormonal contraceptive patch may be referred to by its brand name, EVRA patch, or simply as ‘the patch’. It is a thin, beige, flexible, square patch you wear on your body. It contains two hormones (estrogen and progestin), and works to prevent pregnancy in the same way that the birth control pill does. The patch does not protect against STIs. We always recommend the use of a condom with the patch to reduce the risk of STIs and increase pregnancy protection.
HOW DOES IT WORK?
The patch is worn on the body (buttock, abdomen, upper torso (but not your breasts), or on the outside of your upper arm). Once a week, for three weeks, the user takes off the old patch and applies a new patch. Then the user goes 1 week (7 days) without a patch. Usually the user starts their period within a few days of taking the patch off. At the end of the patch-free week, the user applies a new patch to begin a new cycle.
Each week, the EVRA patch continuously delivers hormones through the skin and into the bloodstream for a full 7 days to prevent pregnancy.Once you apply the patch to your body, these hormones are continuously transferred through your skin and into your bloodstream, where they prevent pregnancy in two ways. First, they prevent ovaries from releasing eggs. Second, they thicken the mucous in the cervix, making it difficult for sperm to enter your uterus.
HOW EFFECTIVE IS IT?
If used perfectly, the patch is 99.7% effective in preventing pregnancy. Based on average use (e.g. not applying it properly), it is 92% effective. The EVRA patch does NOT offer any protection against STIs.
