1998. the efficacy and safety of levonorgestrel and ethinyl estradiol were studied in 2 one-year clinical trials of subjects age 18 to 49. there were no exclusions for body mass index (bmi), weight, or bleeding history. the primary efficacy and safety study (313-na) was a one-year open-label clinical trial that treated 2,134 subjects in north america. of these subjects 1,213 (56.8%) discontinued prematurely, including 102 (4.8%) discontinued by the sponsor for early study closure. the mean weight of subjects in this study was 70.38 kg. the efficacy of levonorgestrel and ethinyl estradiol was assessed by the number of pregnancies that occurred after the onset of treatment and within 14 days of the last dose. among subjects 35 years or less, there were 23 pregnancies (4 of these occurred during the interval 1 to 14 days after the last day of pill use) during 12,572 28-day pill packs of use. the resulting total pearl index was 2.38 (95% ci: 1.51, 3.57) and the one-year life table pregnancy rate was 2.39 (95% ci: 1.57, 3.62). pill pack cycles during which subjects used back-up contraception or were not sexually active were not included in these calculations. among women 35 years or less who took the pills completely as directed, there were 15 pregnancies (method failures) resulting in a pearl index of 1.55 (95% ci: 0.87, 2.56) and the one-year life table pregnancy rate was 1.59 (95% ci: 0.95 to 2.67). in a second supportive study conducted in europe (315-eu), 641 subjects were randomized to levonorgestrel and ethinyl estradiol (n=323) or the cyclic comparator of 0.1 mg levonorgestrel and 0.02 mg ethinyl estradiol (n=318). the mean weight of subjects in this study was 63.86 kg. the efficacy analysis among women 35 years or less included 2,756 levonorgestrel and ethinyl estradiol pill packs and 2,886 cyclic comparator pill packs. there was one pregnancy in the levonorgestrel and ethinyl estradiol group that occurred within 14 days following the last dose. there were three pregnancies in the cyclic comparator group. the bleeding profile for subjects in study 313-na also was assessed. women with a history of unscheduled bleeding and/or spotting were not excluded from the study. in those subjects who provided complete bleeding data, the percentage of patients who were amenorrheic in a given cycle and remained amenorrheic through cycle 13 (cumulative amenorrhea rate) was determined (figure 2). figure 2: percentage of subjects with cumulative amenorrhea for each pill pack through pill pack 13 when prescribing levonorgestrel and ethinyl estradiol, the convenience of having no scheduled menstrual bleeding should be weighed against the inconvenience of unscheduled bleeding and spotting (see warnings, 11 ). levonorgestrel and ethinyl estradiol tablets are contraindicated in females who are known to have or develop the following conditions : thrombophlebitis or thromboembolic disorders history of deep-vein thrombophlebitis or thromboembolic disorders cerebrovascular or coronary artery disease (current or past history) valvular heart disease with thrombogenic complications thrombogenic rhythm disorders hereditary or acquired thrombophilias major surgery with prolonged immobilization diabetes with vascular involvement headaches with focal neurological symptoms such as aura uncontrolled hypertension current diagnosis of, or history of, breast cancer, which may be hormone-sensitive carcinoma of the endometrium or other known or suspected estrogen-dependent neoplasia undiagnosed abnormal genital bleeding cholestatic jaundice of pregnancy or jaundice with prior pill use hepatic adenomas or carcinomas, or active liver disease known or suspected pregnancy hypersensitivity to any of the components of levonorgestrel and ethinyl estradiol. are receiving hepatitis c drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for alt elevations (see warnings, risk of liver enzyme elevations with concomitant hepatitis c treatment) .

for tablets containing 20 mcg of ethinyl estradiol and 100 mcg of levonorgestrel 1 dose is 5 tablets; for tablets containing 30 mcg of ethinyl estradiol and 150 mcg of levonorgestrel 1 dose is 4 tablets. 10. however, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches 6 months of age. in a clinical trial with levonorgestrel and ethinyl estradiol tablets, 1,477 subjects had 7,720 cycles of use and a total of 5 pregnancies were reported. this represents an overall pregnancy rate of 0.84 per 100 woman-years. this rate includes patients who did not take the drug correctly. one or more pills were missed during 1,479 (18.8%) of the 7,870 cycles; thus all tablets were taken during 6,391 (81.2%) of the 7,870 cycles. of the total 7,870 cycles, a total of 150 cycles were excluded from the calculation of the pearl index due to the use of backup contraception and/or missing 3 or more consecutive pills. combination oral contraceptives should not be used in women with any of the following conditions: thrombophlebitis or thromboembolic disorders a history of deep-vein thrombophlebitis or thromboembolic disorders cerebrovascular or coronary artery disease (current or past history) valvular heart disease with thrombogenic complications thrombogenic rhythm disorders hereditary or acquired thrombophilias major surgery with prolonged immobilization diabetes with vascular involvement headaches with focal neurological symptoms uncontrolled hypertension current diagnosis of, or history of, breast cancer, which may be hormone-sensitive undiagnosed abnormal genital bleeding cholestatic jaundice of pregnancy or jaundice with prior pill use hepatic adenomas or carcinomas, or active liver disease known or suspected pregnancy hypersensitivity to any of the components of falmina women who are receiving hepatitis c drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for alanine aminotransferase (alt) elevations (see warnings, risk of liver enzyme elevations with concomitant hepatitis c treatment ).
