Name: Mestranol and norethindrone

What is the most important information I should know about birth control pills?

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

You should not take birth control pills if you have any of the following conditions: uncontrolled high blood pressure, heart disease, a blood-clotting disorder, circulation problems, diabetic problems with your eyes or kidneys, unusual vaginal bleeding, liver disease or liver cancer, severe migraine headaches, or if you have ever had breast or uterine cancer, jaundice caused by birth control pills, a heart attack, a stroke, or a blood clot.

Taking birth control pills can increase your risk of blood clots, stroke, or heart attack, especially if you have certain other conditions, or if you are overweight.

Smoking can increase your risk of blood clot, stroke, or heart attack while taking birth control pills. You should not take mestranol and norethindrone if you smoke and are older than 35 years of age.

What should I discuss with my healthcare provider before taking birth control pills?

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 greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not take combination birth control pills if you smoke and are over 35 years old.

Do not use if you are pregnant or think you might be 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.

You should not take birth control pills if you have:

  • untreated or uncontrolled high blood pressure;

  • heart disease (coronary artery disease, uncontrolled heart valve disorder, history of heart attack, stroke, or blood clot);

  • a blood-clotting disorder or circulation problems;

  • problems with your eyes, kidneys or circulation caused by diabetes;

  • a history of hormone-related cancer such as breast or uterine cancer;

  • unusual vaginal bleeding that has not been checked by a doctor;

  • liver disease or liver cancer;

  • severe migraine headaches (with aura, numbness, weakness, or vision changes), especially if you are older than 35;

  • a history of jaundice caused by pregnancy or birth control pills; or

  • if you smoke and are over 35 years old.

To make sure birth control pills are safe for you, tell your doctor if you have:

  • high blood pressure, varicose veins;

  • high cholesterol or triglycerides, or if you are overweight;

  • a history of depression;

  • underactive thyroid;

  • gallbladder disease;

  • diabetes;

  • seizures or epilepsy;

  • a history of irregular menstrual cycles;

  • tuberculosis; 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.

Usual Adult Dose for Endometriosis

Mestranol-norethindrone products are packaged in 21 or 28 day dosage preparations. The last seven tablets in 28 day dosage preparations are hormonally inert.

Regardless of the number of tablets in a package, the cycle length for oral contraceptives is generally considered to be 28 days. (The first day of menstrual bleeding is counted as day 1.)

This product can be administered in two ways.

When initiating a Sunday start regimen, the first tablet may be taken on the first Sunday after menstruation begins. If a period begins on a Sunday, the first tablet may be taken on that day. When initiating a Sunday start regimen, another contraceptive method should be used until after the first 7 consecutive days of administration. For a 28 day package, one tablet is taken daily for 28 days and a new package begun on the following day. For a 21 day package, one tablet is taken daily for 21 days followed by 7 days with no medication. A new package of contraceptives is begun on the following day.

When initiating a Day 1 start regimen, the first tablet is taken on the first day on menstruation. Such initiation may increase the risk of spotting and breakthrough bleeding but decrease the risk of early ovulation and pregnancy. For a 28 day package, one tablet is taken daily for 28 days and a new package begun on the following day. For a 21 day package, one tablet is taken daily for 21 days followed by 7 days with no medication. A new package of contraceptives is begun on the following day.

Missed Doses

If a woman misses one dose of active tablets, the missed dose should be taken as soon as it is remembered and the normal schedule should be resumed.

If a woman misses two doses in week 1 or week 2 of the cycle, 2 tablets may be taken as soon as they are remembered and 2 tablets taken the next day and the normal schedule may be resumed.

If a woman misses two doses in week 3 or three doses at any time in the cycle, Day 1 starters should discard the current package and begin a new package that same day. Sunday starters should take 1 tablet daily from the current package until Sunday, when the current package is discarded and a new package begun.

Mestranol / norethindrone Breastfeeding Warnings

Both the estrogens and progestins occurring in commercially available oral contraceptive formulations are excreted into human milk in very small amounts. The American Academy of Pediatrics considers use of oral contraceptive combinations to be compatible with breast-feeding despite rare reports of breast enlargement in the nursing infant and the possibility of a decrease in milk production and protein content.

Some studies have examined the effect of progestin-only contraceptives on breast-feeding. The extent to which such studies have bearing on oral contraceptive combinations is uncertain. Use of such formulations has not been reported to be associated with deleterious effects on breast-fed infants.
