Ortho Evra Patch
The ORTHO EVRA birth control patch is a highly effective, weekly hormonal birth control patch that contains estrogen and progestin and is worn on the skin to prevent pregnancy. The patch is worn for one week and replaced on the same day of the week for three consecutive weeks, with the fourth week "patch-free." ORTHO EVRA combines the efficacy of the birth control pill with once-a-week dosing. The Patch keeps you from becoming pregnant by delivering continuous levels of the hormones norelgestromin and ethinyl estradiol (progestin and estrogen, respectively) through the skin and into the bloodstream (this is called transdermal administration).
