Medically reviewed on February 1, Patients should be counseled that oral contraceptives do not protect against transmission of HIV AIDS and other sexually transmitted diseases STDs such as chlamydia, genital alesse without prescription, genital warts, gonorrhea, alesse without prescription, hepatitis B, and syphilis.
The Alesse brand alesse without prescription has been discontinued in the U, alesse without prescription. If generic versions of this product have been approved by the FDA, there may be generic equivalents available. The inactive ingredients present are cellulose, hypromellose, alesse without prescription, iron oxide, lactose, magnesium stearate, polacrilin potassium, polyethylene glycol, titanium dioxide, and montanic ester wax.
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. No specific investigation of the absolute bioavailability of Alesse in humans has been conducted.
After a single dose of Alesse to 22 women under fasting conditions, maximum serum concentrations of levonorgestrel are 2. At steady state, attained from day 19 onwards, maximum levonorgestrel concentrations of alesse without prescription. The minimum serum levels of levonorgestrel at steady state are 1.
The kinetics of total levonorgestrel are non-linear due to an increase in binding of levonorgestrel to sex hormone binding globulin SHBGwhich is attributed to increased SHBG levels that are induced by the daily administration of ethinyl estradiol.
The minimum serum levels of ethinyl estradiol at steady state are Levonorgestrel in serum is primarily bound to SHBG. 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.
The 2-hydroxy metabolite is further transformed by methylation and glucuronidation prior to urinary and fecal excretion. Levels of Cytochrome P CYP3A vary widely among individuals and can explain the alcohol ok in skin care in rates of ethinyl estradiol 2-hydroxylation. Ethinyl estradiol is excreted in the alesse without prescription and feces as glucuronide and sulfate conjugates, and undergoes enterohepatic circulation.
Based on the pharmacokinetic study with Alesse, there are no apparent differences in pharmacokinetic parameters among women of different races. No formal studies have evaluated the effect of hepatic disease on the disposition of Alesse. However, steroid hormones may be poorly metabolized in patients with impaired liver function. No formal studies have evaluated the effect of renal disease on the dispositionof Alesse.
Alesse 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. Table II lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. Correct and consistent use of methods can result in lower failure rates. The FDA has concluded that certain combined oral contraceptives containing ethinyl estradiol and norgestrel or levonorgestrel are safe and effective for use as postcoital emergency contraception.
LAM is a highly effective, alesse without prescription, temporary method of contraception. The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The FDA has declared the following dosage regimens of oral contraceptives to be safe and effective for emergency contraception: In a clinical trial with Alesse levonorgestrel and ethinyl estradiol tablets1, subjects had 7, cycles of use and a total of 5 pregnancies were reported.
This represents an overall pregnancy rate of 0, alesse without prescription. This rate includes patients who did not take the drug correctly. One or more pills were missed during 1, Combination oral contraceptives should not be used in women with any of the following conditions: Thrombophlebitis or thromboembolic disorders A 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 Uncontrolled hypertension Known or suspected carcinoma of the breast or personal history of breast cancer 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 alesse without prescription, or active liver disease Known or suspected alesse without prescription Hypersensitivity to any of the components of Alesse.
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 alesse without prescription 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, and strokehepatic neoplasia, gallbladder disease, and hypertension, although the risk of serious morbidity or mortality is very small in healthy women without underlying risk factors.
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 alesse without prescription 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: 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, alesse without prescription.
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. 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 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 can antibiotics affect a stress test shown to increase substantially in smokers over the age of 35 and nonsmokers over the age of 40 FIGURE II among women who use oral contraceptives.
Oral contraceptives may compound the effects of well-known risk factors, such alesse without prescription hypertension, diabetes, hyperlipidemias, age, and obesity. Against vitamin c supplents particular, some progestogens are known to decrease HDL cholesterol and cause glucose intolerance, while estrogens may create a state of hyperinsulinism.
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.
An increased risk of venous thromboembolic and thrombotic disease associated with the use of oral contraceptives is well established. Case control studies have found the relative risk of users compared to non-users to be 3 for the first episode of superficial venous thrombosis, 4 to 11 for deep-vein thrombosis or pulmonary embolism, and 1. Cohort studies have shown the relative risk to be somewhat lower, alesse without prescription, about 3 for new cases and about 4.
However, the incidence is less than that associated with pregnancy 6 per 10, woman-years, alesse without prescription. 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 alesse without prescription not related to length of use and gradually disappears after pill use is stopped.
A two- to four-fold increase in relative risk of postoperative thromboembolic complications has been reported with the use of oral contraceptives. The relative alesse without prescription 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 alesse without prescription thromboembolism and during and following prolonged immobilization.
Since the immediate postpartum period alesse without prescription 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.
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. 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.
The relative risk of hemorrhagic stroke is reported to be 1. 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. 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 alesse without prescription 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, alesse without prescription. New acceptors of oral-contraceptive agents should be started on preparations containing the lowest estrogen content which is judged appropriate for the individual patient.
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 persists for at least 9 years for women years who had used oral contraceptives for five or more years, alesse without prescription, 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.
However, alesse without prescription, both studies were performed with oral contraceptive formulations containing 50 mcg or higher of estrogens. 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 III, alesse without prescription. 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. 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 alesse without prescription 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 alesse without prescription in 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 formulationsthere are greater potential health risks associatedwith 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.
Ory, Family Planning Alesse without prescription, Numerous epidemiological studies have examined the association between the use of oral contraceptives and the incidence of breast and cervical cancer. The risk of having breast cancer diagnosed may be slightly increased among current and recent users of combination oral contraceptives. However, alesse without prescription, this excess risk appears to decrease over time after combination oralcontraceptive discontinuation and by 10 years after cessation the increased risk disappears.
