Dolishale

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.

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 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 ).

Similar effects on risk factors have been associated with an increased risk of heart disease. Oral contraceptives must be used with caution in women with cardiovascular disease risk factors. b. Venous Thrombosis and Thromboembolism An increased risk of venous thromboembolic and thrombotic disease associated with the use of oral contraceptives is well established.

The risk of venous thrombotic and thromboembolic events is further increased in women with conditions predisposing for venous thrombosis and thromboembolism. 5 to 6 for women with predisposing conditions for venous thromboembolic disease.

5 for new cases requiring hospitalization. 5 to 3 per 10,000 woman-years for non-users. However, the incidence is less than that associated with pregnancy (6 per 10,000 woman-years). The excess risk is highest during the first year a woman ever uses a combined oral contraceptive.

Venous thromboembolism may be fatal. The risk of thromboembolic disease due to oral contraceptives is not related to length of use and gradually disappears after pill use is stopped. A post-marketing observational study evaluated the risk of venous thromboembolism with levonorgestrel and ethinyl estradiol tablets use in two large US automated healthcare claims databases.

The study was not completed as planned due to low accrual of levonorgestrel and ethinyl estradiol tablets users in these databases and discontinuation of the product from the market due to low usage. 1 per 10,000 person-years among the users of cyclic oral contraceptives containing the progestin levonorgestrel and 20 mcg of ethinyl estradiol.

Adjustment for important risk factors or confounders (such as obesity, cardiovascular disease and other diseases) for venous thromboembolism could not be performed due to the small sample size. Although the study results suggest an elevated risk of venous thromboembolism with current levonorgestrel and ethinyl estradiol tablets use compared to cyclic oral hormonal contraceptive use, reliable interpretation of the results is significantly limited due to the small sample size and concerns over unmeasured and uncontrolled confounding, as well as questions about the suitability of the comparator selection and the validity of the venous thromboembolism definition.

A two-to-four fold increase in relative risk of postoperative thromboembolic complications has been reported with the use of oral contraceptives. The relative risk of venous thrombosis in women who have predisposing conditions is twice that of women without such medical conditions.

If feasible, oral contraceptives should be discontinued at least four weeks prior to and for two weeks after elective surgery of a type associated with an increase in risk of thromboembolism and during and following prolonged immobilization.

Since the immediate post-partum period is also associated with an increased risk of thromboembolism, oral contraceptives should be started no earlier than four weeks after delivery in women who elect not to breast-feed, or after a midtrimester pregnancy termination.

c. Cerebrovascular Diseases Oral contraceptives have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest among older (>35 years), hypertensive women who also smoke.

Hypertension was found to be a risk factor for both users and nonusers, for both types of strokes, while smoking interacted to increase the risk for hemorrhagic strokes. Transient ischemic attacks have also been associated with oral contraceptive use.

In a large study, the relative risk of thrombotic strokes has been shown to range from 3 for normotensive users to 14 for users with severe hypertension. 7 for users with severe hypertension. The attributable risk is also greater in older women.

Oral contraceptives also increase the risk for stroke in women with other underlying risk factors such as certain inherited or acquired thrombophilias. Women with migraine (particularly migraine/headaches with focal neurological symptoms such as aura) who take combination oral contraceptives may be at an increased risk of stroke.

) d. Dose-Related Risk of Vascular Disease From Oral Contraceptives A positive association has been observed between the amount of estrogen and progestogen in oral contraceptives and the risk of vascular disease. A decline in serum high-density lipoproteins (HDL) has been reported with many progestational agents.

A decline in serum high-density lipoproteins has been associated with an increased incidence of ischemic heart disease. Because estrogens increase HDL cholesterol, the net effect of an oral contraceptive depends on a balance achieved between doses of estrogen and progestogen and the nature and absolute amount of progestogen used in the contraceptive.

The amount of both hormones should be considered in the choice of an oral contraceptive. Minimizing exposure to estrogen and progestogen is in keeping with good principles of therapeutics. For any particular estrogen/progestogen combination, the dosage regimen prescribed should be one which contains the least amount of estrogen and progestogen that is compatible with a low failure rate and the needs of the individual patient.

New acceptors of oral contraceptive agents should be started on preparations containing the lowest estrogen content which is judged appropriate for the individual patient. e. Persistence of Risk of Vascular Disease There are two studies which have shown persistence of risk of vascular disease for ever-users of oral contraceptives.

In a study in the United States, the risk of developing myocardial infarction after discontinuing oral contraceptives persisted for at least 9 years for women 40 to 49 years who had used oral contraceptives for five or more years, but this increased risk was not demonstrated in other age groups.

In another study in Great Britain, the risk of developing cerebrovascular disease persisted for at least 6 years after discontinuation of oral contraceptives, although excess risk was very small. 05 mg or higher of estrogens. 2. Estimates of Mortality From Contraceptive Use One study gathered data from a variety of sources which have estimated the mortality rate associated with different methods of contraception at different ages (Table 3).

These estimates include the combined risk of death associated with contraceptive methods plus the risk attributable to pregnancy in the event of method failure. Each method of contraception has its specific benefits and risks. The study concluded that with the exception of oral contraceptive users 35 and older who smoke and 40 and older who do not smoke, mortality associated with all methods of birth control is less than that associated with childbirth.

The observation of a possible increase in risk of mortality with age for oral contraceptive users is based on data gathered in the 1970's — but not reported until 1983. However, current clinical practice involves the use of lower estrogen dose formulations combined with careful restriction of oral contraceptive use to women who do not have the various risk factors listed in this labeling.

Because of these changes in practice, and also because of some limited new data which suggest that the risk of cardiovascular disease with the use of oral contraceptives may now be less than previously observed, the Fertility and Maternal Health Drugs Advisory Committee was asked to review the topic in 1989.

The Committee concluded that although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy nonsmoking women (even with the newer low-dose formulations), there are greater potential health risks associated with pregnancy in older women and with the alternative surgical and medical procedures which may be necessary if such women do not have access to effective and acceptable means of contraception.

Therefore, the Committee recommended that the benefits of oral contraceptive use by healthy nonsmoking women over 40 may outweigh the possible risks. Of course, older women, as all women who take oral contraceptives, should take the lowest possible dose formulation that is effective.

W. Ory, Family Planning Perspectives, 15:57 to 63, 1983. 3. Malignant Neoplasms Breast Cancer DOLISHALE is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications].

Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer.

However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use [see Postmarketing Experience]. Cervical Cancer Some studies suggest that oral contraceptive use has been associated with an increase in the risk of cervical intraepithelial neoplasia or invasive cervical cancer in some populations of women.

However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors. Endometrial biopsies performed in a subset of subjects (Study 1; n = 93) ages 18 to 49 years, after 6 to 12 months of use of levonorgestrel and ethinyl estradiol, did not reveal any hyperplasias or malignancies.

Endometrial malignancy is rare in this age group, so change in the risk is unlikely to be detected with a study of this size. 4. Hepatic Neoplasia Benign hepatic adenomas are associated with oral contraceptive use, although the incidence of these benign tumors is rare in the United States.

3 cases/100,000 for users, a risk that increases after four or more years of use. Rupture of rare, benign, hepatic adenomas may cause death through intra-abdominal hemorrhage. Studies from Britain have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) oral contraceptive user.

S. and the attributable risk (the excess incidence) of liver cancers in oral contraceptive users approaches less than one per million users. 5. RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/ paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications such as COCs.

Discontinue DOLISHALE prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ ritonavir, with or without dasabuvir [see Contraindications (4)] . DOLISHALE can be restarted approximately 2 weeks following completion of treatment with the combination drug regimen.

6. Ocular Lesions There have been clinical case reports of retinal thrombosis associated with the use of oral contraceptives that may lead to partial or complete loss of vision. Oral contraceptives should be discontinued if there is unexplained partial or complete loss of vision; onset of proptosis or diplopia; papilledema; or retinal vascular lesions.

Appropriate diagnostic and therapeutic measures should be undertaken immediately. 7. Oral Contraceptive Use Before or During Early Pregnancy Extensive epidemiological studies have revealed no increased risk of birth defects in infants born to women who have used oral contraceptives prior to pregnancy.

Studies also do not suggest a teratogenic effect, particularly insofar as cardiac anomalies and limb-reduction defects are concerned, when taken inadvertently during early pregnancy (see CONTRAINDICATIONS section). The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy.

Oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion. The possibility of pregnancy should be considered in any patient who may be experiencing symptoms of pregnancy, especially if she has not adhered to the prescribed schedule.

Oral-contraceptive use must be discontinued if pregnancy is confirmed. 8. Gallbladder Disease Combination oral contraceptives may worsen existing gallbladder disease and may accelerate the development of this disease in previously asymptomatic women.

Earlier studies have reported an increased lifetime relative risk of gallbladder surgery in users of oral contraceptives and estrogens. More recent studies, however, have shown that the relative risk of developing gallbladder disease among oral contraceptive users may be minimal.

The recent findings of minimal risk may be related to the use of oral contraceptive formulations containing lower hormonal doses of estrogens and progestogens. 9. Carbohydrate and Lipid Metabolic Effects Oral contraceptives have been shown to cause glucose intolerance in a significant percentage of users.

075 mg of estrogens cause hyperinsulinism, while lower doses of estrogen cause less glucose intolerance. Progestogens increase insulin secretion and create insulin resistance, this effect varying with different progestational agents.

However, in the nondiabetic woman, oral contraceptives appear to have no effect on fasting blood glucose. Because of these demonstrated effects, prediabetic and diabetic women should be carefully observed while taking oral contraceptives.

A small proportion of women will have persistent hypertriglyceridemia while on the pill. As discussed earlier (see WARNINGS , 1a. ), changes in serum triglycerides and lipoprotein levels have been reported in oral contraceptive users.

10. Elevated Blood Pressure An increase in blood pressure has been reported in women taking oral contraceptives and this increase is more likely in older oral contraceptive users and with continued use. Data from the Royal College of General Practitioners and subsequent randomized trials have shown that the incidence of hypertension increases with increasing quantities of progestogens.

Women with a history of hypertension or hypertension-related diseases, or renal disease should be encouraged to use another method of contraception. If women with hypertension elect to use oral contraceptives, they should be monitored closely and if significant elevation of blood pressure occurs, oral contraceptives should be discontinued (see CONTRAINDICATIONS section).

For most women, elevated blood pressure will return to normal after stopping oral contraceptives, and there is no difference in the occurrence of hypertension among ever- and never-users. 11. Headache The onset or exacerbation of migraine or development of headache with a new pattern that is recurrent, persistent, or severe requires discontinuation of oral contraceptives and evaluation of the cause.

(See WARNINGS , 1c. ) 12. Bleeding Irregularities When prescribing DOLISHALE, the convenience of having no scheduled menstrual bleeding should be weighed against the inconvenience of unscheduled breakthrough bleeding and spotting. In Study 313-NA, 385/2,134 (18%) of women discontinued prematurely due to bleeding that was reported either as an adverse event or where bleeding was given as one of the reasons for discontinuation (see INDICATIONS AND USAGE , Clinical Studies ).

Figure 4 shows the percentage of levonorgestrel and ethinyl estradiol subjects in study 313-NA by pill pack who experienced unscheduled bleeding or spotting only (Defined as "No sanitary protection required"). Figure 5 shows the percentage of levonorgestrel and ethinyl estradiol tablet subjects with complete bleeding data in Study 313-NA who had 4 or more and 7 or more days of bleeding and/or spotting during each pill pack cycle.

During pill pack 2, 67% of subjects experienced 4 or more days of bleeding and/or spotting and 54% of these subjects experienced 7 or more days of bleeding and/or spotting. During the final cycle of use of levonorgestrel and ethinyl estradiol (pill pack 13), these percentages were 31% and 20%, respectively.

As in any case of bleeding irregularities, nonhormonal causes should be considered and adequate diagnostic measures may be indicated to rule out pregnancy, infection, malignancy, or other conditions. Some women may encounter post-pill amenorrhea or oligomenorrhea (possibly with anovulation), especially when such a condition was preexistent.

13. Ectopic Pregnancy Ectopic as well as intrauterine pregnancy may occur in contraceptive failures. Image Image Image
