Ortho Evra
The Birth Control Patch
What is it? Ortho Evra is a
highly effective, weekly hormonal birth control patch that is worn on the
skin to prevent pregnancy. The patch is worn for 1 week at a time and is
replaced on the same day of the week for 3 consecutive weeks. The fourth
week is patch-free. It is a reversible form of contraception that does not
affect future fertility.
How does it work? The patch delivers
continuous levels of 2 hormones, estrogen and progesterone, through the skin
and into the blood stream. It is 99% effective when used correctly. It may
be slightly less effective in women with body weight > 198 pounds.
What are the side effects?
Minor
Some of the most common side effects include
breast tenderness, headache, nausea, skin irritation at the application
site, breakthrough bleeding, and menstrual cramps.
Major
Serious side effects include blood clots,
stroke or heart attack, and are increased if you smoke cigarettes. Some
women should not use the patch, including individuals with a history of
blood clots, heart attack, stroke, or certain cancers.
