What Is Levonorgetsrel And Ethinyl Estradiol Used For?

INDICATIONS AND USAGE Levonorgestrel and Ethinyl Estradiol tablets are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptives are highly effective. Table 2 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and Norplant ® System, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

Dosage and Administration

DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, levonorgestrel and ethinyl estradiol tablets must be taken exactly as directed and at intervals not exceeding 24 hours. The dosage of levonorgestrel and ethinyl estradiol tablets is one white tablet daily for 21 consecutive days, followed by one orange inert tablet daily for 7 consecutive days, according to the prescribed schedule. It is recommended that levonorgestrel and ethinyl estradiol tablets be taken at the same time each day. During The First Cycle Of Use The possibility of ovulation and conception prior to initiation of medication should be considered. The patient should be instructed to begin taking levonorgestrel and ethinyl estradiol tablets on either the first Sunday after the onset of menstruation (Sunday Start) or on Day 1 of menstruation (Day 1 Start). Sunday start: The patient is instructed to begin taking levonorgestrel and ethinyl estradiol tablets on the first Sunday after the onset of menstruation. If menstruation begins on a Sunday, the first tablet (white) is taken that day. One white tablet should be taken daily for 21 consecutive days, followed by one orange inert tablet daily for 7 consecutive days. Withdrawal bleeding should usually occur within 3 days following discontinuation of white tablets and may not have finished before the next pack is started. During the first cycle, contraceptive reliance should not be placed on levonorgestrel and ethinyl estradiol tablets until a white tablet has been taken daily for 7 consecutive days, and a nonhormonal back-up method of birth control should be used during those 7 days. Day 1 start: During the first cycle of medication, the patient is instructed to begin taking levonorgestrel and ethinyl estradiol tablets during the first 24 hours of her period (day one of her menstrual cycle). One white tablet should be taken daily for 21 consecutive days, followed by one orange inert tablet daily for 7 consecutive days. Withdrawal bleeding should usually occur within 3 days following discontinuation of white tablets and may not have finished before the next pack is started. If medication is begun on day one of the menstrual cycle, no back-up contraception is necessary. If levonorgestrel and ethinyl estradiol tablets are started later than day one of the first menstrual cycle or postpartum, contraceptive reliance should not be placed on levonorgestrel and ethinyl estradiol tablets until after the first 7 consecutive days of administration, and a nonhormonal back-up method of birth control should be used during those 7 days. After the first cycle of use The patient begins her next and all subsequent courses of tablets on the day after taking her last orange tablet. She should follow the same dosing schedule: 21 days on white tablets followed by 7 days on orange tablets. If in any cycle the patient starts tablets later than the proper day, she should protect herself against pregnancy by using a nonhormonal back-up...

Side Effects (Adverse Reactions)

ADVERSE REACTIONS An increased risk of the following serious adverse reactions (see WARNINGS section for additional information) has been associated with the use of oral contraceptives: Thromboembolic and thrombotic disorders and other vascular problems (including thrombophlebitis and venous thrombosis with or without pulmonary embolism, mesenteric thrombosis, arterial thromboembolism, myocardial infarction, cerebral hemorrhage, cerebral thrombosis), carcinoma of the reproductive organs and breasts, hepatic neoplasia (including hepatic adenomas or benign liver tumors), ocular lesions (including retinal vascular thrombosis), gallbladder disease, carbohydrate and lipid effects, elevated blood pressure, and headache including migraine. Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 3). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 3). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to 10 years of COC use. FIGURE 3: Relevant Studies of Risk of Breast Cancer with Combined Oral Contraceptives RR = relative risk; OR = odds ratio; HR = hazard ratio. “ever COC” are females with current or past COC use; “never COC use” are females that never used COCs. The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug related (alphabetically listed): Acne Amenorrhea Anaphylactic/anaphylactoid reactions, including urticaria, angioedema, and severe reactions with respiratory and circulatory symptoms Breast changes: tenderness, pain, enlargement, secretion Budd-Chiari syndrome Cervical erosion and secretion, change in Cholestatic jaundice Chorea, exacerbation of Colitis Contact lenses, intolerance to Corneal curvature (steepening), change in Dizziness Edema/fluid retention Erythema multiforme Erythema nodosum Gastrointestinal symptoms (such as abdominal pain, cramps, and bloating) Hirsutism Infertility after discontinuation of treatment, temporary Lactation, diminution in, when given immediately postpartum Libido, change in Melasma/chloasma which may persist Menstrual flow, change in Mood changes, including depression Nausea Nervousness Pancreatitis Porphyria, exacerbation of Rash (allergic) Scalp hair, loss of Serum folate levels, decrease in Spotting Systemic lupus erythematosus, exacerbation of Unscheduled bleeding Vaginitis, including candidiasis Varicose veins, aggravation of Vomiting Weight or appetite (increase or decrease), change in The following adverse reactions have been reported in users of oral contraceptives: Cataracts Cystitis-like syndrome Dysmenorrhea Hemolytic uremic syndrome Hemorrhagic eruption Optic neuritis, which may lead to partial or complete loss of vision Premenstrual syndrome Renal function, impaired figure-3

Warnings and Precautions

WARNINGS Cigarette smoking increases the risk of serious cardiovascular side effects from oral-contraceptive use. This risk increases with age and with the extent of smoking (in epidemiologic studies, 15 or more cigarettes per day was associated with a significantly increased risk) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke. The use of oral contraceptives is associated with increased risks of several serious conditions including venous and arterial thrombotic and thromboembolic events (such as myocardial infarction, thromboembolism, and stroke), hepatic neoplasia, gallbladder disease, and hypertension, although the risk of serious morbidity or mortality is very small in healthy women without underlying risk factors. The risk of morbidity and mortality increases significantly in the presence of other underlying risk factors such as certain inherited or acquired thrombophilias, hypertension, hyperlipidemias, obesity, diabetes, and surgery or trauma with increased risk of thrombosis (see CONTRAINDICATIONS). Practitioners prescribing oral contraceptives should be familiar with the following information relating to these risks. The information contained in this package insert is principally based on studies carried out in patients who used oral contraceptives with higher doses of estrogens and progestogens than those in common use today. The effect of long-term use of the oral contraceptives with lower doses of both estrogens and progestogens remains to be determined. Throughout this labeling, epidemiological studies reported are of two types: retrospective or case control studies and prospective or cohort studies. Case control studies provide a measure of the relative risk of disease, namely, a ratio of the incidence of a disease among oral-contraceptive users to that among nonusers. The relative risk does not provide information on the actual clinical occurrence of a disease. Cohort studies provide a measure of attributable risk, which is the difference in the incidence of disease between oral-contraceptive users and nonusers. The attributable risk does provide information about the actual occurrence of a disease in the population. For further information, the reader is referred to a text on epidemiological methods. 1. Thromboembolic Disorders and Other Vascular Problems a. Myocardial infarction An increased risk of myocardial infarction has been attributed to oral-contraceptive use. This risk is primarily in smokers or women with other underlying risk factors for coronary-artery disease such as hypertension, hypercholesterolemia, morbid obesity, and diabetes. The relative risk of heart attack for current oral-contraceptive users has been estimated to be two to six. The risk is very low under the age of 30. Smoking in combination with oral-contraceptive use has been shown to contribute substantially to the incidence of myocardial infarction in women in their...
