Duofem is an emergency contraceptive product that is designed to prevent the starting of a pregnancy. It uses levonorgestrel, a synthetic form of progestin that is also found in other oral contraceptives, to accomplish this. Duofem is used when other contraception has failed, or if you have had intercourse without using contraception. If a pregnancy has already started, or if one starts even if you use emergency contraception, Duofem will not harm the fetus. It is not an abortion pill; its end is to prevent fertilization, and it does not work by harming a fertilized embryo.
Duofem is intended for use by women from eighteen years up to menopause. It is important to remember, though, that oral contraceptives are only effective as long as they are taken regularly. This is true whether they are taken to prevent pregnancy, to treat acne, or to regulate menstrual flow. You should keep taking Duofem even if you experience side effects.
These side effects may include spotting, upset stomach, nausea or vomiting, stomach cramps, diarrhea or constipation, bloating, swelling of the gums, weight gain or loss, skin patches, acne, irregular hair growth, spotting between periods, missed periods, breast tenderness, difficulty wearing contact lenses, redness or irritation of the vagina, or white discharge from your vagina. Other more serious side effects can include severe headache, severe vomiting, slurred speech or difficulty speaking, dizziness, weakness of numbness of the arms or legs, chest pain or heaviness, coughing up blood, difficulty breathing, pain in the back of the lower leg, loss of vision or double vision, bulging eyes, severe stomach pain, jaundice, loss of appetite, extreme fatigue or weakness, fever, dark urine, light-colored stool, swelling of the hands, feet or ankles, depression, or rash. If you experience any of these, you should call your doctor immediately.
Before you take Duofem, you should tell your doctor if you are allergic to progestin, estrogen or any medications, including herbal or over-the-counter medications. It is especially important that you tell your doctor if you are taking acetaminophen, antibiotics, antifungals, HIV protease inhibitors, or St. John’s Wort. You should also exercise caution if you have ever had jaundice during pregnancy or while you were taking another oral contraceptive, if you have ever had problems with your breasts, including lumps or fibrocystic breast disease, if you have had high blood pressure, diabetes, asthma, strokes, migraines, angina, blood clots in your lungs, coronary artery disease, depression, unexplained vaginal bleeding, excessive weight gain during your menstrual cycle, or diseases of the liver, heart, kidney, or gallbladder.
You should not take any oral contraceptives, including Duofem, if you are pregnant or planning to become pregnant, or if you are breast-feeding. You should let your doctor know if you become pregnant while you rare taking Duofem or any other contraceptive. If you miss periods while you are taking any contraceptive, you may already be pregnant, and you should see your doctor for a pregnancy test.
