What is ethinyl estradiol and norelgestromin?
Ethinyl estradiol and norelgestromin contains a combination of female hormones that
prevent ovulation (the release of an egg from an ovary). This medication also causes changes in
your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder
for a fertilized egg to attach to the uterus.
Ethinyl estradiol and norelgestromin are used as contraception to prevent pregnancy.
Ethinyl estradiol and norelgestromin may also be used for other purposes not listed in this
medication guide.

How should I take ethinyl estradiol and norelgestromin?
Use this medication exactly as it was prescribed for you. Do not use more skin patches or
wear them for longer than recommended by your doctor. You will apply your first patch on the
first day of your period or on the first Sunday after your period begins (follow your doctor's
instructions).
Place the patch on your skin and press it into place firmly for 10 seconds. Make sure the
edges stick well. You will wear the patch for a full week.
Apply the patch to clean, dry skin on any of these areas: the outside of your upper arm,
your stomach, your buttocks, or your upper back. Do not apply the patch to skin that is broken or
irritated, or to a skin area that may be rubbed by tight clothing (such as a waistband).
Remove the patch and apply a new one on the same day each week for three weeks in a
row. Check your patch every day to make sure it is sticking well to your skin. At the end of the
third week, remove the patch and do not apply a new one for 7 full days. Your period should
start during this time
Do not allow more than 7 days to pass before starting your
next 3-week patch cycle.
