What is ethinyl estradiol and norgestimate?

Ethinyl estradiol and norgestimate is a combination birth control pill that contains female hormones to stop ovulation (the release of an egg from an ovary). Ethinyl estradiol and norgestimate also changes your cervical mucus and uterine lining, making it more difficult for sperm to reach the uterus and for a fertilized egg to attach to the uterus.

Ethinyl estradiol and norgestimate is used as contraception to prevent pregnancy. There are many brands of this medicine available. Not all brands are mentioned in this leaflet.

Ethinyl estradiol and norgestimate may also be used for other purposes not listed in this medication guide.

How should I take birth control pills?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

You may need to use back-up birth control, like condoms with spermicide, when you first start using this medicine. Follow your doctor's instructions.

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 take one pill daily.

Some birth control packs have "reminder" pills to help you stay on your regular cycle. Your period will usually begin while you are using these reminder pills.

You may have breakthrough bleeding, especially during the first 3 months. Tell your doctor if this bleeding continues or is very heavy.

Use a back-up birth control if you are sick with severe vomiting or diarrhea.

If you need major surgery or will be on long-term bed rest, you may need to stop using this medicine for a short time. Any doctor or surgeon who treats you should know that you are using Ethinyl estradiol and norgestimate.

While taking birth control pills, you will need to visit your doctor regularly.

Store this medicine at room temperature away from moisture and heat.
