🩺 Clinical
Oral contraceptives (birth-control pills) containing ethinyl estradiol (an estrogen) and levonorgestrel (a progestin) are used to prevent pregnancy. Estrogen and progestin are two female sex hormones. Combinations of estrogen and progestin work 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 DOLISHALE is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception.
The efficacy of these contraceptive methods, except sterilization, the IUD, and implants, depend upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

The FDA has declared the following dosage regimens of oral contraceptives to be safe and effective for emergency contraception: for tablets containing 50 mcg of ethinyl estradiol and 500 mcg of norgestrel 1 dose is 2 tablets; for tablets containing 20 mcg of ethinyl estradiol and 100 mcg of levonorgestrel 1 dose is 5 tablets;…
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, DOLISHALE (levonorgestrel and ethinyl estradiol tablets) must be taken exactly as directed and at intervals not exceeding 24 hours. The possibility of ovulation and conception prior to initiation of medication should be considered. Women who do not wish to become pregnant after discontinuation should be advised to immediately use another method of birth control.
The dosage of DOLISHALE is one green tablet daily without any tablet-free interval. It is recommended that DOLISHALE tablets be taken at the same time each day. Initiation of Therapy Instructions for beginning DOLISHALE are provided in Table 4 below.
Table 4 Current contraceptive therapy DOLISHALE start day Nonhormonal back-up method of birth control needed when correctly starting DOLISHALE? None Day 1 of patient's menstrual cycle (during the first 24 hours of her period) No 21-day COC regimen OR 28-day COC regimen Day 1 of patient's withdrawal bleed, at the latest 7 days after her last active tablet. No Progestin-only pill Day after taking a progestin-only pill Yes, for the first 7 days of DOLISHALE tablet taking Implant Day of implant removal Yes, for the first 7 days of DOLISHALE tablet taking Injection Day the next injection is due Yes, for the first 7 days of DOLISHALE tablet taking If spotting or unscheduled 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 health care professional. The possibility of ovulation increases with each successive day that scheduled green tablets are missed. If the patient has not adhered to the prescribed schedule (missed one or more tablets or started taking them on a day later than she should have), the probability of pregnancy should be considered.
Hormonal contraception must be discontinued if pregnancy is confirmed. The risk of pregnancy increases with each tablet missed. For additional patient instructions regarding missed tablets, see the WHAT TO DO IF YOU MISS PILLS section in the DETAILED PATIENT LABELING below.
DOLISHALE may be initiated no earlier than day 28 postpartum in the nonlactating mother or after a second-trimester abortion due to the increased risk for thromboembolism (see CONTRAINDICATIONS , WARNINGS , and PRECAUTIONS concerning thromboembolic disease). The patient should be advised to use a nonhormonal back-up method for the first 7 days of tablet-taking. However, if intercourse has already occurred, pregnancy should be excluded before the start of combined oral contraceptive use or the patient must wait for her first menstrual period.
In the case of first-trimester abortion, if the patient starts DOLISHALE immediately, additional contraceptive measures are not needed.
⛔ Contraindications ▾
CONTRAINDICATIONS Combination oral contraceptives should not be used in women with any of 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 DOLISHALE • 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 Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with the extent of smoking (in epidemiologic studies, 15 or more cigarettes per day was associated with a significantly increased risk) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to 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, stroke, and transient ischemic attack), 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 DOLISHALE is a non-cyclic oral contraceptive that provides a low daily dose of estrogen and progestin; however, DOLISHALE provides women with more hormonal exposure on a yearly basis (13 additional weeks of hormone intake per year) than conventional cyclic oral contraceptives containing the same strength of synthetic estrogens and similar strength of progestins. 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 infarction 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 3) among women who use oral contraceptives. Figure 3: Circulatory Disease Mortality Rates per 100,000 Woman Years by Age, Smoking Status and Oral Contraceptive Use 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 choleste…
🤒 Adverse Reactions ▾
ADVERSE REACTIONS 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 6). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 6). 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 6.
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 (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, transient ischemic attack), carcinoma of the reproductive organs and breasts, hepatic neoplasia/liver disease (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.
The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug related (alphabetically listed): • Acne • Amenorrhea • Anaphylactic/anaphylactoid reactions, including urticaria, angioedema, and severe reactions with respiratory and circulatory symptoms • Breast changes: tenderness, pain, enlargement, secretion • Budd-Chiari syndrome • Cervical erosion and secretion, change in • Cholestatic jaundice • Chorea, exacerbation of • Colitis • Contact lenses, intolerance to • Corneal curvature (steepening), change in • Dizziness • Edema/fluid retention • Erythema multiforme • Erythema nodosum • Focal nodular hyperplasia • Gastrointestinal symptoms (such as abdominal pain, cramps, and bloating) • Hirsutism • Infertility after discontinuation of treatment, temporary • Lactation, diminution in, when given immediately postpartum • Libido, change in • Melasma/chloasma which may persist • Menstrual flow, change in • Mood changes, including depression • Nausea • Nervousness • Pancreatitis • Porphyria, exacerbation of • Rash (allergic) • Scalp hair, loss of • Serum folate levels, decrease in • Spotting • Systemic lupus erythematosus, exacerbation of • Unscheduled bleeding • Vaginitis, including candidiasis • Varicose veins, aggravation of • Vomiting • Weight or appetite (increase or decrease), change in The following adverse reactions have been reported in users of oral contraceptives: • Cataracts • Cystitis-like syndrome • Dysmenorrhea • Hemolytic uremic syndrome • Hemorrhagic eruption • Optic neuritis, which may lead to partial or complete loss of vision • Premenstrual syndrome • Renal function, impaired To report SUSPECTED ADVERSE REACTIONS, contact Ingenus Pharmaceuticals, LLC Toll-Free at 1-877-748-1970 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . image001.jpg
🆘 Overdosage ▾
OVERDOSAGE Symptoms of oral contraceptive overdosage in adults and children may include nausea, vomiting, breast tenderness, dizziness, abdominal pain, drowsiness/fatigue; withdrawal bleeding may occur in females. There is no specific antidote and further treatment of overdose, if necessary, is directed to the symptoms.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Mode of Action 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). Pharmacokinetics Absorption No specific investigation of the absolute bioavailability of levonorgestrel and ethinyl estradiol tablets in humans has been conducted.
However, literature indicates that levonorgestrel is rapidly and completely absorbed after oral administration (bioavailability about 100%) and is not subject to first-pass metabolism. Ethinyl estradiol is rapidly and almost completely absorbed from the gastrointestinal tract but, due to first-pass metabolism in gut mucosa and liver, the bioavailability of ethinyl estradiol is between 38% and 48%. A summary of the single dose and multiple dose levonorgestrel and ethinyl estradiol pharmacokinetic parameters for 18 women under fasting conditions is provided in Table 1.
The plasma concentrations of levonorgestrel and ethinyl estradiol reached steady-state by approximately day 14. Levonorgestrel and ethinyl estradiol concentrations did not increase from days 14 to 28, but did increase from days 1 to 28. Table 1: Mean (SD) Pharmacokinetic Parameters of Levonorgestrel and Ethinyl Estradiol Tablets Over a 28-Day Dosing Period LNG Day C max (ng/mL) T max (h) t 1/2 (h) AUC 0-24 (ng•h/mL) 1 2.4 (0.9) 1.2 (0.4) - 16 (8) 14 5.4 (2.1) 1.7 (1.4) - 68 (36) 28 5.7 (2.1) 1.3 (0.8) 36 (19) 74 (41) EE Day (pg/mL) (h) (h) (pg h/mL) 1 47.7 (20.1) 1.3 (0.5) - 378 (140) 14 72.7 (37.2) 1.4 (0.5) - 695 (361) 28 74.4 (29.7) 1.4 (0.5) 21 (7) 717 (351) The mean plasma concentrations of levonorgestrel and ethinyl estradiol following single (day 1) and multiple (days 14 and 28) oral administrations of levonorgestrel 90 mcg in combination with ethinyl estradiol 20 mcg to 18 healthy women is provided in Figure 1.
Figure 1: Mean Plasma ± SD † Concentrations of Levonorgestrel and Ethinyl Estradiol Following Single (Day 1) and Multiple (Days 14 and 28) Oral Administrations of Levonorgestrel 90 mcg in Combination with Ethinyl Estradiol 20 mcg to Healthy Women The effect of food on the rate and the extent of levonorgestrel and ethinyl estradiol absorption following oral administration of DOLISHALE has not been evaluated. Distribution Levonorgestrel in serum is primarily bound to sex hormone-binding globulin (SHBG). Ethinyl estradiol is about 97% bound to serum albumin.
Ethinyl estradiol does not bind to SHBG, but induces SHBG synthesis. Metabolism Levonorgestrel: The most important metabolic pathways are reduction of the Δ4-3-oxo group and hydroxylation at positions 2α, 1β, and 16β, followed by conjugation. Most of the circulating metabolites are sulfates of 3α, 5β-tetrahydro-levonorgestrel, while excretion occurs predominantly in the form of glucuronides.
Some of the parent levonorgestrel also circulates as 17β-sulfate. Metabolic clearance rates may differ among individuals by several-fold, and this may account in part for the wide variation observed in levonorgestrel concentrations among users. Ethinyl estradiol: Cytochrome P450 enzymes (CYP3A4) in the liver are responsible for the 2-hydroxylation that is the major oxidative reaction.
The 2-hydroxy metabolite is further transformed by methylation, sulfation, and glucuronidation prior to urinary and fecal excretion. Levels of CYP3A4 vary widely among individuals and can explain the variation in rates of ethinyl estradiol 2-hydroxylation. Excretion The terminal elimination half-life for levonorgestrel in levonorgestrel and ethinyl estradiol tablets is about 36 hours.
Levonorgestrel and its metabolites are excreted in the urine (40% to 68%) and in feces (16% to 48%). The terminal elimination half-life of ethinyl estradiol in levonorgestrel and ethinyl estradiol tablets is about 21 hours. Ethiny…
