Cigarette smoking increases the risk of serious cardiovascular side effects from hormonal contraceptive use. This risk increases with age and with the number of cigarettes smoked and is marked in women over 35 years of age. Women who are over 35 years of age and smoke should not use ethinyl estradiol/norelgestromin. A significantly increased risk of venous thromboembolism was found among women aged 15 to 44 years who used ethinyl estradiol/norelgestromin patch compared with oral contraceptives containing 30 to 35 mcg of ethinyl estradiol (EE) and either levonorgestrel or norgestimate. Increased estrogen exposure from the patch may increase the risk of adverse events, including venous thromboembolism, compared with oral contraceptives .

Uses For ethinyl estradiol and norelgestromin
Norelgestromin and ethinyl estradiol combination contraceptive skin patch is used to prevent pregnancy. Hormones from the patch are absorbed through your skin into your body. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization is prevented.
This patch allows more estrogen into the blood than oral birth control containing the same amount of estrogen.
No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective. Discuss with your doctor your options for birth control.
Norelgestromin/Ethinyl Estradiol does not prevent AIDS or other sexually transmitted diseases. It will not prevent hepatitis B. It will not help as emergency contraception, such as after unprotected sexual contact.
ethinyl estradiol and norelgestromin is available only with your doctor's prescription.

Proper Use of ethinyl estradiol and norelgestromin
To make using hormonal contraceptives as safe and reliable as possible, you should understand how and when to use them and what effects may be expected.
A patient information leaflet will be given to you with your filled prescription, and will provide many details concerning the use of hormonal contraceptives. Read and follow the instructions carefully and ask your doctor if you need additional information or explanation.
This transdermal patch system is to be used for 28 days (four-week) cycle. A new patch is applied each week for 3 weeks (21 days), and week four is patch-free.
When you begin using norelgestromin and ethinyl estradiol transdermal, your body will require at least 7 days to adjust before a pregnancy will be prevented. Use a second form of contraception, such as a condom, spermicide, or diaphragm, for the first 7 days of your first cycle.
To use: Keep each patch in the package until you are ready to use it. Wash your hands with soap and water before and after applying a patch. Apply the patch to clean, dry, and intact skin on the abdomen or stomach, upper body, the upper outside part of the arm, or the buttocks. Avoid touching the sticky surface of the patch. Make sure there is no lotion, powder, cream, or make-up on the skin. Apply the patch and then press it with the palm of your hand for 10 seconds to make sure it sticks. Change the location of the patch each time you apply a new one. Do not apply a patch to skin that is injured, broken, or cut. Do not apply a patch to your breasts. Check the patch every day to make sure it is in place.
If the patch comes off partly or all the way, try to apply it again or apply a new patch. If it was loose less than 24 hours, no other form of birth control is needed. If the patch has peeled away for more than 24 hours, apply a new patch and start a new cycle. A second form of birth control should be used.
If the patch is not sticky or has stuck to material or itself, remove it and apply a new patch. Do not hold the patch in place with tape or wraps.
If you are switching from a contraceptive pill to using the patch, start the patch on the first day of your period. If you do not start your period after 5 days, you see your doctor for a pregnancy test. If you start the patch later than the first day of your period, use a second method of birth control with the patch for the first 7 days.
If you have a miscarriage or an abortion in the first trimester of your pregnancy, you may start norelgestromin/ethinyl estradiol transdermal right away. You do not need a second form of birth control. If you start ethinyl estradiol and norelgestromin 5 days or more after the miscarriage or abortion, you should use a second form of birth control with the patch for the first 7 days. If you have a miscarriage or abortion after the first trimester, you should wait for 4 weeks before starting ethinyl estradiol and norelgestromin.
If you have bleeding with the patch in place, continue to use the patches as usual. If the bleeding continues for 2–3 cycles, call your doctor. If you do not have your period during the time the patch is off, stay on your regular schedule and call your doctor.
If the patch is uncomfortable or causing irritation, change to a new patch in a new location. Change the patch again on your regular schedule. Do not use more than one patch at a time.
When you remove a patch, carefully fold it in half so that it sticks to itself and throw it away. There will still be some hormones on the patch. Do not touch the inside of the patch.
The dose of ethinyl estradiol and norelgestromin will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of ethinyl estradiol and norelgestromin. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
Your doctor may begin your patch on the first day of your menstrual period (called Day-1 start) or on Sunday (called Sunday start). When you begin on a certain day it is important that you follow that schedule, even if you forget to change a patch. Do not change your schedule on your own. If the schedule that you have been put on is not convenient, check with your doctor about changing schedules.
