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.
