The Patch

The patch is a very thin, beige, smooth patch that measures 1 3/4" inches on each of its four sides, which is used to prevent pregnancy. It works similarly to the birth control pill. The contraceptive patch keeps you from becoming pregnant by delivering continuous levels of the hormones progesterone and estrogen through the skin and into the bloodstream. Also called transdermal administration, it can be found in 10mg and 20mg strengths.
