Perfect Typical use - unintended pregnancy Advantage- A hormonal patch that is put on once a week for three weeks, than no patch for a week. Problems arise if they fall off or are forgotten. They do not protect against STD's. They do need a prescription.
This is a good method for women who have trouble remembering a daily pill. The Ortho Evra patch is worn on the skin and changed only once a week for three weeks with a fourth week that is patch-free. The patch releases the same types of hormones as the birth control pill and is just as effective. In its Perfect Use one would still practice safe sex with a condom, but its Typical Use is thinking it can stop a STD and remembering to change it. It also has some side effects!
The patch is affective if used properly and if you are less then 200 pounds. One advantage is you don't have to remember it everyday. One disadvantage is it can get stuck on clothing and is more visible to everyone
