🩺 Clinical
Oral contraceptives (birth-control pills) containing ethinyl estradiol (an estrogen) and norethindrone (a progestin) are used to prevent pregnancy. Estrogen and progestin are two female sex hormones. Combinations of estrogen and progestin work mainly by preventing ovulation (the release of eggs from the ovaries). Oral contraceptives are an effective method of birth control, but they do not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.

🎯 Indications and Usage ▾
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 1 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.

⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION The following is a summary of the instructions given to the patient in the " HOW TO TAKE THE PILL " section of the DETAILED PATIENT LABELING. The patient is given instructions in five (5) categories: 1. IMPORTANT POINTS TO REMEMBER: The patient is told (a) that she should take one pill every day at the same time, (b) many women have spotting or light bleeding or gastric distress during the first one to three cycles, (c) missing pills can also cause spotting or light bleeding, (d) she should use a back-up method for contraception if she has vomiting or diarrhea or takes some concomitant medications, and/or if she has trouble remembering the pill, (e) if she has any other questions, she should consult her physician.
2. BEFORE SHE STARTS TAKING HER PILLS: She should decide what time of day she wishes to take the pill, check whether her pill pack has 28 pills, and note the order in which she should take the pills (diagrammatic drawings of the pill pack are included in the patient insert). 3.
WHEN SHE SHOULD START THE FIRST PACK: The Day-One start is listed as the first choice and the Sunday start (the Sunday after her period starts) is given as the second choice. If she uses the Sunday start she should use a back-up method in the first cycle if she has intercourse before she has taken seven pills. 4.
WHAT TO DO DURING THE CYCLE: The patient is advised to take one pill at the same time every day until the pack is empty. If she is on the 28 day regimen, she should start the next pack the day after the last inactive tablet and not wait any days between packs. 5.
WHAT TO DO IF SHE MISSES A PILL OR PILLS: The patient is given instructions about what she should do if she misses one, two or more than two pills at varying times in her cycle for both the Day-One and the Sunday start. The patient is warned that she may become pregnant if she has unprotected intercourse in the seven days after missing pills. To avoid this, she must use another birth control method such as condom, foam, or sponge in these seven days.
⛔ Contraindications ▾
CONTRAINDICATIONS Philith is contraindicated in females who are known to have or develop the following conditions: •Thrombophlebitis or thromboembolic disorders •A past history of deep vein thrombophlebitis or thromboembolic disorders •Cerebrovascular or coronary artery disease •Current diagnosis of, or history of, breast cancer, which may be hormonesensitive •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 ).
⚠️ Warnings ▾
WARNINGS The use of oral contraceptives is associated with increased risk of several serious conditions including myocardial infarction, thromboembolism, stroke, hepatic neoplasia, and gallbladder disease, 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 hypertension, hyperlipidemias, obesity and diabetes. 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 formulations of estrogens and progestogens than those in common use today. The effect of long-term use of the oral contraceptives with lower formulations 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 a 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. *Adapted from Stadel BB: Oral contraceptives and cardiovascular disease. N Engl J Med , 1981; 305: 612-618, 672-677; with author's permission.
1. Thromboembolic Disorders and Other Vascular Problems: The physician should be alert to the earliest manifestations of thromboembolic thrombotic disorders as discussed below. Should any of these occur or be suspected the drug should be discontinued immediately. 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 infarctions in women in their mid-thirties or older, with smoking accounting for the majority of excess cases. Mortality rates associated with circulatory disease have been shown to increase substantially in smokers over the age of 35 and nonsmokers over the age of 40 (Figure 1) among women who use oral contraceptives.
Layde PM, Beral V: Further analyses of mortality in oral contraceptive users: Royal College of General Practitioners' oral contraception study. (Table 5) Lancet 1981;1:541-546. Oral contraceptives may compound the effects of well-known risk factors, such as hypertension, diabetes, hyperlipidemias, age and obesity.
In particular, some progestogens are known to decrease HDL cholesterol and cause glucose intolerance, while estrogens may create a state of hyperinsulinism. Oral contraceptives have been shown to increase blood pressure among users (see section 10 in WARNINGS ). Such increases in risk factors have been associated with an increased risk of heart disease and the risk increases with the number of risk factors present.
Oral contraceptives must be used with caution in women with cardiovascular disease risk factors. b. Thromboembolism: An increased risk of thromboembolic and thrombotic disease associated with the use of oral contraceptives i…

Post Marketing Experience: 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 Contraceptive Use 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 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, and secretion •Change in weight (increase or decrease) •Change in cervical ectropion and secretion •Possible 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: •Premenstrual 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 image description
🆘 Overdosage ▾
OVERDOSAGE Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. NONCONTRACEPTIVE HEALTH BENEFITS: The following noncontraceptive health benefits related to the use of oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg of mestranol.
Effects on menses: •Increased menstrual cycle regularity •Decreased blood loss and decreased incidence of iron deficiency anemia •Decreased incidence of dysmenorrhea Effects related to inhibition of ovulation: •Decreased incidence of functional ovarian cysts •Decreased incidence of ectopic pregnancies Effects from long-term use: •Decreased incidence of fibroadenomas and fibrocystic disease of the breast •Decreased incidence of acute pelvic inflammatory disease •Decreased incidence of endometrial cancer •Decreased incidence of ovarian cancer
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Combination oral contraceptives act by suppression of gonadotropins. Although the primary mechanism of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation).

References are available upon request. BRIEF SUMMARY PATIENT PACKAGE INSERT This product (like all oral contraceptives) is intended to prevent pregnancy.
It does not protect against HIV infection (AIDS) and other sexually transmitted diseases. Oral contraceptives, also known as "birth control pills" or "the pill," are taken to prevent pregnancy and when taken correctly, have a failure rate of about 1% per year when used without missing any pills. The typical failure rate of large numbers of pill users is less than 3% per year when women who miss pills are included.
Oral contraceptive use is associated with certain serious diseases that can be life-threatening or may cause temporary or permanent disability. The risks associated with taking oral contraceptives increase significantly if you: •Smoke •Have high blood pressure, diabetes, high cholesterol •Have or have had clotting disorders, heart attack, stroke, angina pectoris, cancer of the breast or sex organs, jaundice or malignant or benign liver tumors. You should not take the pill if you suspect you are pregnant or have unexplained vaginal bleeding.
Most side effects of the pill are not serious. The most common side effects are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses. These side effects, especially nausea and vomiting, may subside within the first three months of use.
The serious side effects of the pill occur very infrequently, especially if you are in good health and are young. However, you should know that the following medical conditions have been associated with or made worse by the pill: 1. Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), stoppage or rupture of a blood vessel in the brain (stroke), blockage of blood vessels in the heart (heart attack or angina pectoris), or other organs of the body.
As mentioned above, smoking increases the risk of heart attacks and strokes and subsequent serious medical consequences. 2. Liver tumors, which may rupture and cause severe bleeding.
A possible but not definite association has been found with the pill and liver cancer. However, liver cancers are extremely rare. The chance of developing liver cancer from using the pill is thus even rarer.
3. High blood pressure, although blood pressure usually returns to normal when the pill is stopped. The symptoms associated with these serious side effects are discussed in the detailed leaflet given to you with your supply of pills.
Notify your doctor or health care provider if you notice any unusual physical disturbances while taking the pill. In addition, drugs such as rifampin, as well as some anticonvulsants and some antibiotics may decrease oral contraceptive effectiveness. There may be slight increases in the risk of breast cancer among current users of hormonal birth control pills with longer duration of use of 8 years or more.
Studies to date of women taking the pill have not shown an increase in the incidence of cancer of the breast or cervix. There is, however, insufficient evidence to rule out the possibility that the pill may cause such cancers. Taking the pill provides some important noncontraceptive effects.
These include less painful menstruation, less menstrual blood loss and anemia, fewer pelvic infections, and fewer cancers of the ovary and the lining of the uterus. Be…
