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 contraceptive products such as Norinyl, which contain 50 mcg of estrogen, should not be used unless medically indicated. Oral contraceptives are highly effective. Table I lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception.1 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 I: Percentage of women experiencing an unintended pregnancy during the first year of typical use and the 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 Unintended 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 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. 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. (1) (2) (3) (4) Emergency Contraceptive Pills: Treatment initiated within 72 hours after unprotected intercourse reduces the risk of pregnancy by at least 75%.The treatment schedule is one dose within 72 hours after unprotected intercourse and a second dose 12 hours after the first dose. The Food and Drug Administration has declared the following brands of oral contraceptives to be safe and effective for emergency contraception: Ovral (1 dose is 2 white pills), Aleese (1 dose is 5 pink pills), Nordette or Levlen (1 dose is 2 light-orange pills), Lo/Ovral (1 dose is 4 white pills), Triphasil or Tri-Levlen (1 dose is 4 yellow pills). Lactational Amenorrhea Method: LAM is a highly effective, temporary method of contraception.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 six months of age.

New York, NY: Irvington Publishers, 1998. ChanceThe percents 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 percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether. 85 85 SpermicidesFoams, creams, gels, vaginal suppositories, and vaginal film. 26 6 40 Periodic abstinence 25 63 Calendar 9 Ovulation method 3 Sympto-thermalCervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. 2 Post-ovulation 1 Withdrawal 19 4 CapWith spermicidal cream or jelly.

contraindications
CONTRAINDICATIONS Oral contraceptives should not be used in women who 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, carcinomas or benign liver tumors Known or suspected pregnancy Are receiving Hepatitis C 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).
Special warnings and precautions
PRECAUTIONS GENERAL Patients should be counseled that this product does not protect against HIV infection (AIDS) and other sexually transmitted diseases. 1. 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. 2. 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. 3. LIVER FUNCTION If jaundice develops in any woman receiving oral contraceptives the medication should be discontinued. Steroid hormones may be poorly metabolized in patients with impaired liver function. 4. 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. 5. EMOTIONAL DISORDERS Women with a history of depression should be carefully observed and the drug discontinued if depression recurs to a serious degree. 6. CONTACT LENSES Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist. 7. 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.76 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer TRI-NORINYL tablets with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations (see Warnings, RISK OF LIVER ENZYME ELEVATIOSN WITH CONCOMITANT HEPATITIS C TREATMENT). 8. INTERACTIONS WITH LABORATORY TESTS Certain endocrine and liver function tests and blood components may be affected by oral contraceptives: a. Increased prothrombin and factors VII, VIII, IX, and X; decreased antithrombin 3; increased norepinephrine-induced platelet aggregability. b. 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. c. Other binding proteins may be elevated in serum. d. Sex steroid binding globulins are increased and result in elevated levels of total circulating sex steroids and corticoids; however, free or biologically active levels remain unchanged. e. Triglycerides may be increased. f. Glucose tolerance may be decreased. g. 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. 9. CARCINOGENESIS See WARNINGS section. 10. PREGNANCY Pregnancy Category X See CONTRAINDICATIONS and WARNINGS sections. 11. 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. 12. PEDIATRIC USE Safety and efficacy of Tri-Norinyl 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 the 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, carcinomas 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 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 To achieve maximum contraceptive effectiveness, oral contraceptives must be taken exactly as directed and at intervals not exceeding 24 hours. For a DAY 1 START, count the first day of menstrual flow as Day 1 and the first blue tablet is then taken on Day 1. For a SUNDAY START when menstrual flow begins on or before Sunday, the first blue tablet is taken on that day. With either a DAY 1 START or SUNDAY START, 1 blue tablet is taken for 7 days, then 1 yellow-green tablet for 9 days, then 1 blue tablet for 5 days, then 1 orange tablet (inert) for 7 days, whether bleeding has stopped or not. With either a DAY 1 START or SUNDAY START 1 tablet is taken each day at the same time for 28 days. After all 28 tablets are taken, whether bleeding has stopped or not, the same dosage schedule is repeated beginning on the following day.
Pregnancy and lactation
11. 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.

Warnings Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.
