Hailey is a combination birth control pill containing 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.

Hailey is used as contraception to prevent pregnancy. Hailey is also used to treat moderate acne in women who are at least 15 years old and have started having menstrual periods, and who wish to use birth control pills. There are many available brands of ethinyl estradiol and norethindrone. Not all brands are listed on this leaflet.

Hailey may also be used for purposes not listed in this medication guide.

Do not use birth control pills if you are pregnant or if you have recently had a baby.

You should not use birth control pills if you have: uncontrolled high blood pressure, heart disease, coronary artery disease, circulation problems (especially with diabetes), undiagnosed vaginal bleeding, liver disease or liver cancer, severe migraine headaches, if you also take certain hepatitis C medication, if you will have major surgery, if you smoke and are over 35, or if you have ever had a heart attack, a stroke, a blood clot, jaundice caused by pregnancy or birth control pills, or cancer of the breast, uterus/cervix, or vagina.

Smoking, especially if you are older than 35, or taking birth control pills can increase your risk of blood clots, stroke, or heart attack.

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, such as condoms with spermicide, when you first start using this medication. 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 following day. You may get pregnant if you do not take one pill daily.

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

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

You may have breakthrough bleeding. Tell your doctor if it continues or is very heavy.

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 Hailey.

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

Store at room temperature away from moisture and heat.

Taking birth control pills can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of taking birth control pills. Your risk is also high when you restart birth control pills after not taking them for 4 weeks or longer.

Smoking can increase your risk of blood clots, stroke, or heart attack caused by birth control pills, especially if you are older than 35.

Do not use if you are pregnant. Stop using Hailey and tell your doctor right away if you become pregnant, or if you miss 2 menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control pills.
