Do not take 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: heart problems, coronary artery disease, circulation problems, undiagnosed vaginal bleeding, liver problems, 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.

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

You will take your first pill on the first day of your period or on the first Sunday after your period begins. You may need to use back-up birth control, such as condoms or a spermicide, when you first start using birth control pills. 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. Get your prescription refilled before you run out of pills completely.

Some 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.

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

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

Any doctor or surgeon who treats you should know that you are using birth control pills.

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

If you miss a reminder pill, throw it away and keep taking one reminder pill per day until the pack is empty.
