You are buying 1 box of 21 Nordette Contraceptive birth control tablets (Ethinyl estradiol & levonorgestre)
Ethinyl estradiol and levonorgestrel 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.
Take this medication exactly as it was prescribed for you. Do not take larger amounts, or take it for longer than recommended by your doctor. You will take your first pill on the first day of your period or on the first Sunday after your period begins (follow your doctor's instructions).
You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medication. Follow your doctor's instructions.
Some 28-day birth control packs contain seven "reminder" pills to keep you on your regular cycle. Your period will usually begin while you are using these reminder pills.
Breakthrough bleeding may occur, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.
Take one pill every day, no more than 24 hours apart. When the pills run out, start a new pack the next day. You may get pregnant if you do not use this medication regularly.
If you need to have any type of medical tests or surgery, or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using birth control pills.
