US Brand Names
Norelgestromin/Ethinyl Estradiol 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.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
- Patch, Extended Release

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.
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 had a baby and are not breastfeeding, you should wait 4 weeks before you start this medicine. If you have not had a period after having your baby, you should make sure you are not pregnant before starting this medicine.
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 this medicine 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 this medicine.
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 this medicine 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 this medicine. 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.

Follow your doctor's orders or the directions on the label if you forget to change your patch. The following information includes only some of the ways to handle this. Your doctor may want you to stop using the medicine and use other birth control methods for the rest of the month until you have your menstrual period. Then your doctor can tell you how to begin using your medicine again. If you forget to apply your patch during the 1st week, apply it as soon as possible and start a new cycle. Use a second form of birth control for the first week of the new cycle. You will now have a new patch start day. If you forget to change your patch in the 2nd or 3rd week for one or two days, change it as soon as you remember. No other form of birth control is needed. If you forget to change your patch in the 2nd or 3rd week for more than two days, change to a new patch and start a new cycle. Use a second form of birth control for the first week of the new cycle. If you forget to remove your patch at the end of the 3rd week, remove it as soon as possible and then start a new patch on your regular start day. You should never have the patch off for more than 7 days in a row.
Store the patches at room temperature in a closed container, away from heat, moisture, and direct light.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 6 to 12 months, but some doctors require them more often.
Although you are using this medicine to prevent pregnancy, you should know that using this medicine while you are pregnant could harm the unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away.
Tell the medical doctor or dentist in charge that you are using this medicine before any kind of surgery (including dental surgery) or emergency treatment. Your doctor will decide whether you should continue using this medicine.
Norelgestromin/ethinyl estradiol transdermal may not work as well for you if you weigh more than 198 pounds. Talk to your doctor about the kind of birth control that is best for you.
Vaginal bleeding of various amounts may occur between your regular menstrual periods during the first 3 months of use. This is sometimes called spotting when slight, or breakthrough bleeding when heavier. If this should occur:
- Continue on your regular dosing schedule.
- The bleeding usually stops within 1 week.
- Check with your doctor if the bleeding continues for more than 1 week.
- After you have been taking hormonal contraceptives on schedule and for more than 3 months and bleeding continues, check with your doctor.
Missed menstrual periods may occur:
- If you have not used the patch exactly as scheduled. Pregnancy must be considered as a possibility.
- If the medicine is not the right strength or type for your needs.
Check with your doctor if you miss any menstrual periods so that the cause may be determined.
If you suspect that you may have become pregnant, stop using this medicine immediately and check with your doctor.
Using this medicine may increase your risk of blood clots, stroke, or heart attack. Your risk of these serious medical problems is even greater if you smoke cigarettes or if you are over age 35.
You will be exposed to more estrogen if you use this medicine than if you use a typical birth control pill. Increased estrogen exposure may increase the risk of side effects. Talk to your doctor about this risk.
Check with your doctor immediately if you wear contact lenses or if blurred vision, difficulty with reading, or any other change in vision occurs during or after treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
Check with your doctor before refilling an old prescription, especially after a pregnancy. You will need another physical examination and your doctor may change your prescription.
Use with caution around small children. The contraceptive patch may be a choking hazard if swallowed by a child.
