Indication(s)

INDICATIONS AND USAGE Oral contraceptives are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptives are highly effective. Table III 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, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. Table III Percentage of women experiencing an unintended pregnancy during the first year of typical use and first year of perfect use of contraception and the percentage continuing use at the end of the first year. United States. % of Women Experiencing an Accidental Pregnancy within the First Year of Use % of Women Continuing Use at One YearAmong couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. Method (1) Typical UseAmong typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. (2) Perfect UseAmong couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason.

New York NY: Irvington Publishers, 1998. 4 The percentages becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percentage who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether.

Advisory information

contraindications
CONTRAINDICATIONS Oral contraceptives should not be used in women who currently have the following conditions: Thrombophlebitis or thromboembolic disorders A past history of deep-vein thrombophlebitis or thromboembolic disorders Cerebral-vascular or coronary-artery disease Known or suspected carcinoma of the breast 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 Known or suspected pregnancy 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).
Special warnings and precautions
PRECAUTIONS 1. GENERAL Patients should be counseled that this product does not protect against HIV infection (AIDS) and other sexually transmitted diseases. 2. PHYSICAL EXAMINATION AND FOLLOW-UP It is good medical practice for all women to have annual history and physical examinations, 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 and pelvic organs, including cervical cytology and relevant laboratory tests. In case of undiagnosed, persistent or recurrent abnormal vaginal bleeding, appropriate 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. 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. EMOTIONAL DISORDERS Women with a history of depression should be carefully observed and the drug discontinued if depression recurs to a serious degree. 7. CONTACT LENSES Contact-lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist. 8. DRUG INTERACTIONS Reduced efficacy and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. A similar association, though less marked, has been suggested with barbiturates, phenylbutazone, phenytoin sodium, and possibly with griseofulvin, ampicillin and tetracyclines. Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer Sronyx 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). 9. INTERACTIONS WITH LABORATORY TESTS Certain endocrine- and liver-function tests and blood components may be affected by oral contraceptives: Increased prothrombin and factors VII, VIII, IX and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability. Increased thyroid-binding globulin (TBG) leading to increased circulating total thyroid hormone, as measured by protein-bound iodine (PBI), T4 by column or by radioimmunoassay. Free T3 resin uptake is decreased, reflecting the elevated TBG, free T4 concentration is unaltered. Other binding proteins may be elevated in serum. Sex-binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; however, free or biologically active levels remain unchanged. Triglycerides may be increased. Glucose tolerance may be decreased. Serum folate levels may be depressed by oral contraceptive therapy. This may be of clinical significance if a woman becomes pregnant shortly after discontinuing oral contraceptives. 10. CARCINOGENESIS See "WARNINGS" section. 11. PREGNANCY Pregnancy Category X See "CONTRAINDICATIONS" and "WARNINGS" sections. 12. NURSING MOTHERS Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers, and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child. 13. PEDIATRIC USE Safety and efficacy of Levonorgestrel and Ethinyl Estradiol Tablets USP have been established in women of reproductive age. Safety and efficacy are expected to be the same for postpubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated. INFORMATION FOR THE PATIENT See "Patient Labeling" printed below.
Adverse reactions
ADVERSE REACTIONS An increased risk of the following serious adverse reactions has been associated with the use of oral contraceptives (see "WARNINGS" section). Thrombophlebitis Arterial thromboembolism Pulmonary embolism Myocardial infarction Cerebral hemorrhage Cerebral thrombosis Hypertension Gallbladder disease Hepatic adenomas or benign liver tumors There is evidence of an association between the following conditions and the use of oral contraceptives, although additional confirmatory studies are needed: Mesenteric thrombosis Retinal thrombosis The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug related: Nausea Vomiting Gastrointestinal symptoms, (such as abdominal cramps and bloating) Breakthrough bleeding Spotting Change in menstrual flow Amenorrhea Temporary infertility after discontinuation of treatment Edema Melasma which may persist Breast changes: tenderness, enlargement, secretion Change in weight (increase or decrease) Change in cervical erosion and secretion Diminution in lactation when given immediately postpartum Cholestatic jaundice Migraine Rash (allergic) Mental depression Reduced tolerance to carbohydrates Vaginal candidiasis Change in corneal curvature (steepening) Intolerance to contact lenses The following adverse reactions have been reported in users of oral contraceptives and the association has been neither confirmed nor refuted: Pre-menstrual syndrome Cataracts Optic neuritis Changes in appetite Cystitis-like syndrome Headache Nervousness Dizziness Hirsutism Loss of scalp hair Erythema multiforme Erythema nodosum Hemorrhagic eruption Vaginitis Porphyria Impaired renal function Hemolytic uremic syndrome Budd-Chiari syndrome Acne Changes in libido Colitis

Usage information

Dosing and administration
DOSAGE AND ADMINISTRATION Sronyx® (Levonorgestrel and Ethinyl Estradiol Tablets USP) To achieve maximum contraceptive effectiveness, Sronyx must be taken exactly as directed at intervals not exceeding 24-hours. Sronyx is a monophasic preparation plus 7 inert tablets. The dosage of Sronyx is one tablet daily for 21 consecutive days per menstrual cycle plus 7 peach inert tablets according to the prescribed schedule. It is recommended that Sronyx be taken at the same time each day, preferably after the evening meal or at bedtime. During the first cycle of medication, the patient should be instructed to take one white Sronyx tablet daily and then 7 peach inert tablets for twenty-eight (28) consecutive days, beginning on day one (1) of her menstrual cycle. (The first day of menstruation is day one.) Withdrawal bleeding usually occurs within 3 days following the last white tablet. (If Sronyx is first taken later than the first day of the first menstrual cycle of medication or postpartum, contraceptive reliance should not be placed on Sronyx until after the first 7 consecutive days of administration. The possibility of ovulation and conception prior to initiation of medication should be considered.) When switching from another oral contraceptive, Sronyx should be started on the first day of bleeding following the last active tablet taken of the previous oral contraceptive. The patient begins her next and all subsequent 28-day courses of Sronyx on the same day of the week that she began her first course, following the same schedule. She begins taking her white tablets on the next day after ingestion of the last peach tablet, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of Sronyx is started later than the next day, the patient should be protected by another means of contraception until she has taken a tablet daily for seven consecutive days. If spotting or breakthrough bleeding occurs, the patient is instructed to continue on the same regimen. This type of bleeding is usually transient and without significance, however, if the bleeding is persistent or prolonged, the patient is advised to consult her physician. Although the occurrence of pregnancy is highly unlikely if Sronyx is taken according to directions, if withdrawal bleeding does not occur, the possibility of pregnancy must be considered. If the patient has not adhered to the prescribed schedule (missed one or more active tablets or started taking them on a day later than she should have), the probability of pregnancy should be considered at the time of the first missed period and appropriate diagnostic measures taken before the medication is resumed. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out before continuing the contraceptive regimen. The risk of pregnancy increases with each active (white) tablet missed. For additional patient instructions regarding missed pills, see the "WHAT TO DO IF YOU MISS PILLS" section in the DETAILED PATIENT LABELING below. If breakthrough bleeding occurs following missed tablets, it will usually be transient and of no consequence. If the patient misses one or more peach tablets, she is still protected against pregnancy provided she begins taking white tablets again on the proper day. In the nonlactating mother, Sronyx may be initiated postpartum, for contraception. When the tablets are administered in the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered. (See "CONTRAINDICATIONS ," "WARNINGS ," and PRECAUTIONS" concerning thromboembolic disease.) It is to be noted that early resumption of ovulation may occur if bromocriptine mesylate has been used for the prevention of lactation.
Pregnancy and lactation
12. NURSING MOTHERS Small amounts of oral contraceptive steroids have been identified in the milk of nursing mothers, and a few adverse effects on the child have been reported, including jaundice and breast enlargement. In addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk. If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child.

Interactions

8. DRUG INTERACTIONS Reduced efficacy and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. A similar association, though less marked, has been suggested with barbiturates, phenylbutazone, phenytoin sodium, and possibly with griseofulvin, ampicillin and tetracyclines. Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer Sronyx 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).
