VIENVA TM Levonorgestrel and Ethinyl Estradiol Kit, 1 kit — NDC 50090-5580-0 (Billing 50090-5580-00)

WARNINGS WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS Cigarette smoking increases the risk of serious cardiovascular events from combined oral contraceptives (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs, including levonorgestrel and ethinyl estradiol, are contraindicated in women who are over 35 years of age and 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 Cardiovascular and Cerebrovascular Events Use of CHCs increases the risk of cardiovascular events and cerebrovascular events, such as myocardial infarction and stroke. The risk of these events with CHC use is greater in females with concomitant risk factors: age 35 years and older, smoking, hypertension, dyslipidemia, diabetes, or obesity.

The risk increases with increasing age and with increasing number of cigarettes smoked. Venous Thromboembolism Use of CHCs also increases the risk of VTE, such as deep vein thrombosis and pulmonary embolism. The rate of VTE in females using COCs has been estimated to be 3 to 9 cases per 10,000 woman-years.

The VTE risk should be considered in the context of relevant subpopulations of females of reproductive potential who are not taking CHCs (see ADVERSE REACTIONS ). Risk factors for VTE with CHC use include smoking, obesity, family history of VTE, and prolonged immobilization, in addition to other factors that contraindicate use of CHCs (see CONTRAINDICATIONS ). The presence of multiple risk factors for VTE with CHC use may further increase the risk.

The risk of VTE is highest during the first year of CHC use and when restarting hormonal contraception after a break of four weeks or longer. The risk of VTE returns to baseline approximately 3 months after CHC use is discontinued. Postpartum Venous Thromboembolism The risk of VTE is increased during the first six weeks postpartum.

The risk is highest up to four weeks postpartum but remains higher than baseline until at least six weeks postpartum. The presence of multi… [Excerpted — this section continues on DailyMed.]

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 - 1.12 (Figure 2). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). 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 - 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 8-10 years of COC use. Figure 2: 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 associated with the use of oral CHCs were identified in clinical studies or postmarketing reports.

Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Common adverse reactions associated with oral CHCs are headache, abdominal pain, nausea, metrorrhagia, vaginal moniliasis and pain, acne, and vaginitis. Additional adverse reactions that have been reported include the following: Eye disorder: intolerance to contact lenses, steepening of corneal curvature Gastrointestinal disorders: Abdominal bloating, vomiting General disorders and administration site conditions: Edema, fluid retention Hepatobiliary disorders: Cholestatic jaundice Pyschiatric disorders: Change in libido, mood changes Reproductive system and breast disorders: Amenorrhea, breast tenderness, breast pain, breast enlargement, increased cervical mucous, change in menstrual flow, unscheduled bleeding Skin and subcutaneous tissue disorders: Acne, melasma Vascular disorders: Budd-Chiari syndrome, aggravation of varicose veins

PRECAUTIONS 1. General Patients should be counseled that oral contraceptives do not protect against transmission of HIV (AIDS) and other sexually transmitted diseases (STDs) such as chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. 2.

Physical Examination and Follow-Up A periodic personal and family medical history and complete physical examination are appropriate for all women, including women using oral contraceptives. The physical examination, however, may be deferred until after initiation of oral contraceptives if requested by the woman and judged appropriate by the clinician. The physical examination should include special reference to blood pressure, breasts, abdomen, pelvic organs, and relevant laboratory tests.

In case of undiagnosed, persistent, or recurrent abnormal vaginal bleeding, appropriate diagnostic measures should be conducted to rule out malignancy. Women with a strong family history of breast cancer or who have breast nodules should be monitored with particular care. 3.

Lipid Disorders Women who are being treated for hyperlipidemias should be followed closely if they elect to use oral contraceptives. Some progestogens may elevate LDL levels and may render the control of hyperlipidemias more difficult. (See WARNINGS ) A small proportion of women will have adverse lipid changes while taking oral contraceptives.

Nonhormonal contraception should be considered in women with uncontrolled dyslipidemias. Persistent hypertriglyceridemia may occur in a small population of combination oral contraceptive users. Elevations of plasma triglycerides may lead to pancreatitis and other complications.

4. Liver Function If jaundice develops in any woman receiving such drugs, the medication should be discontinued. Steroid hormones may be poorly metabolized in patients with impaired liver function.

5. Fluid Retention Oral contraceptives may cause some degree of fluid retention. They should be prescribed with caution, and only with careful monitoring, in patients with conditions which might be aggravated by fluid retention.

6. Depression Monitor females with a history of depression and discontinue levonorgestrel and ethinyl estradiol if depression recurs to a serious degree. Data on the association of CHCs with onset of depression or exacerbation of existing depression are limited.

7. Contact Lenses Contact-lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist. 8.

Gastrointestinal Diarrhea and/or vomiting may reduce hormone absorption resulting in decreased serum concentrations. If a patient vomits or has diarrhea after taking an active tablet, instruct the patient to not take an additional active tablet on that day and to continue the regimen the next day as prescribed. In case of vomiting or diarrhea that continues for 48 hours or greater, instruct the patient to contact the health care provider and use back-up or alternative contraception until active tablets have been taken for 7 consecutive days after vomiting and diarrhea have resolved.

9. Drug Interactions Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer levonorgestrel and ethinyl estradiol with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations (see WARNINGS , RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT). Changes in Contraceptive Effectiveness Associated with Coadministration of Other Products Contraceptive effectiveness may be reduced when hormonal contraceptives are coadministered with antibiotics, anticonvulsants, and other drugs that increase the metabolism of contraceptive steroids.

This could result in unintended pregnancy or breakthrough bleeding. Examples include rifampin, rifabutin, barbiturates, primidone, phenylbutazone, phenytoin, dexamethasone, carbamazepine, felbamate, oxcarbazepine, topiramate, griseofulvin, and modafinil.
