How does the birth control patch work?
One of the benefits of the Ortho-Evra patch is that it is transdermal. By simply attaching it to one of 4 areas (upper arms, upper back, abdomen, and back), the hormones will seep through skin pores. Birth control effectiveness is not immediate, so folks should abstain from unprotected sex for a few days before the hormones take effect.
It should also be stated that the patch does not prevent or protect HIV or sexually trasmitted diseases.
What the patch does do is prevent pregnancy by preventing ovulation. The patch works by seeping hormones (namely estrogren and progestin) through the skin and through the bloodstream. In my personal case, preventing ovulation also prevents cysts from forming. It also helps me to keep track of when my period will start, which is a major plus for those who have somewhat irregular cycles, like me!
For someone who is pretty bad at keeping track of pills, having the patch is a nice alternative!
