What should I discuss with my healthcare provider before taking mestranol and norethindrone (Necon 1/50, Norinyl 1+50, Ortho-Novum 1/50)?

This medication can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control pills (6 weeks if you are breast-feeding).

Do not use this medication if you have:

• a history of a stroke, blood clot, or circulation problems;
• a hormone-related cancer such as breast or uterine cancer;
• abnormal vaginal bleeding;
• liver disease or liver cancer; or
• a history of jaundice caused by birth control pills.

Before using this medication, tell your doctor if you have any of the following conditions:

• high blood pressure, heart disease, congestive heart failure, angina (chest pain), or a history of heart attack;
• high cholesterol or if you are overweight;
• kidney disease;
• a history of depression;
• diabetes;
• gallbladder disease;
• seizures or epilepsy;
• a history of irregular menstrual cycles; or
• a history of fibrocystic breast disease, lumps, nodules, or an abnormal mammogram.

The hormones in birth control pills can pass into breast milk and may harm a nursing baby. This medication may also slow breast milk production. Do not use if you are breast-feeding a baby.

How should I take mestranol and norethindrone (Necon 1/50, Norinyl 1+50, Ortho-Novum 1/50)?

Take this medication exactly as it was prescribed for you. 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.

The 28-day birth control pack contains 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, 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 following day. Get your prescription refilled before you run out of pills completely.

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.

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