Description
Levonorgestrel and ethinyl estradiol combination is used to prevent pregnancy in women who can get pregnant with a BMI less than 30 kilograms (kg) per square meter (m2). It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.
No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control patches. Discuss your options for birth control with your doctor.
This medicine will not prevent HIV infection or other sexually transmitted diseases. 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
