Conditions in which Conjugated Estrogen (Tablet) needs care, as documented in this source.

• Breast Neoplasms

  Major

  The use of estrogens is generally contraindicated in patients with known or suspected estrogen-dependent neoplasia such as breast and endometrial cancer, since it may stimulate tumor proliferation. High dosages of estrogens may be used for the palliative treatment of inoperable, metastatic breast cancer, but only in appropriately selected men and postmenopausal women.

• Hypertension

  Major

  The risk of myocardial infarction and strokes, including those associated with oral contraceptive use and some estrogen use, is increased in patients with hypertension. Moreover, estrogens (and progestogens) may elevate blood pressure and worsen the hypertension, thus compounding the risk. Clinically significant blood pressure increases have been reported during estrogen therapy, particularly in patients receiving high dosages or treated with oral contraceptive combinations having high progestational activity. These effects also increase with duration of therapy and patient age. Therapy with estrogens should be administered cautiously in patients with preexisting hypertension. Patients should be monitored for changes in cardiovascular status, and their antihypertensive regimen adjusted or estrogen therapy withdrawn as necessary. In patients requiring contraception, alternative methods should be considered for those who are hypertensive, over age 35, and smoke.

• Liver Neoplasms

  Major

  The use of oral contraceptives is contraindicated in patients with liver tumors. An increased risk of benign hepatic adenomas and hepatocellular carcinomas has been associated with long-term, oral estrogen- progestin contraceptive use of at least 4 years and 8 years, respectively. Although these tumors are rare and have not been reported with other types of estrogen or progestogen therapies, any preparation containing estrogens and/or progestogens should probably be avoided in patients with existing tumors of the liver. Hepatic hemangiomas and nodular hyperplasia of the liver have been reported with isolated estrogen therapy.

• Thromboembolism

  Major

  The use of estrogens is considered by manufacturers and some authorities to be contraindicated in patients with active thrombotic or thromboembolic disorders. The use of estrogen-containing oral contraceptives is additionally deemed contraindicated in patients with a history of such disorders and/or current cerebrovascular or coronary artery disease. Females with a history of migraines with aura are at an increased risk for stroke and this stroke risk may be further increased in females who have migraines with aura with use of combination oral contraceptives. Hypercoagulability and changes in various clotting factors and blood components have been observed in women receiving estrogen therapy. Although the clinical significance of these effects is unknown, epidemiological data suggest it may be dose-dependent. The risk is probably slight with the use of newer, low-dose oral contraceptives in the absence of known risk factors (e.g., smoker, particularly over the age of 35; hypertension; hyperlipidemia; obesity; diabetes; age over 40). However, a much more significant risk has been reported with higher dosages, such as those used to treat prostate or metastatic breast cancer or those used in older formulations of birth control pills. Therapy with estrogens should be administered cautiously in the lowest effective dosage and only after careful consideration of risks and benefits. Estrogens should be avoided in patients with a history of thrombotic and thromboembolic disorders associated with estrogen use, except when used in the treatment of breast or prostatic malignancy.

• Uterine Hemorrhage

  Major

  The use of estrogens is contraindicated in patients with undiagnosed, abnormal vaginal bleeding. Prolonged (> 1 year), unopposed estrogen use (i.e. estrogen without concomitant progestin therapy) has been associated with a significant, dose-related risk of endometrial carcinoma. The risk may be offset substantially by the addition of a progestin but may not be completely abolished. Prior to initiating estrogen therapy, appropriate diagnostic tests should be performed in patients with abnormal vaginal bleeding to rule out endometrial malignancy. The same applies if recurrent or persistent bleeding develops during estrogen therapy.

• Depressive Disorder

  Moderate

  The use of oral contraceptives has been associated with an increased incidence of depression. It is uncertain whether this effect is related to the estrogenic or the progestogenic component of the contraceptive, although excess progesterone activity is associated with depression. Patients with a history of depression receiving estrogen and/or progestogen therapy should be followed closely. The manufacturer of medroxyprogesterone recommends monitoring patients who have a history of depression and to not re- administer medroxyprogesterone if depression recurs.

• Eye Diseases

  Moderate

  Estrogens and progestogens may cause retinal thrombosis. 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. Therapy with these agents should be administered cautiously in patients who have preexisting ocular problems and appropriate diagnostic and therapeutic measures should be instituted. Contact lens wearers who develop visual changes or changes in lens tolerance should be assessed by an ophthalmologist.

  Moderate

  A two- to four-fold increase in risk of gallbladder disease has been noted in women receiving postmenopausal estrogen therapy. The risk for gallbladder disease may be less for premenopausal women using oral contraceptives containing low-dose estrogens and/or progestins. Therapy with estrogens should be administered cautiously in patients with preexisting gallbladder disease.

• Glucose Intolerance

  Moderate

  Impaired glucose tolerance has been observed in some patients administered oral contraceptives and appears to be related primarily to the estrogen dose. However, progestogens can increase insulin secretion and produce insulin resistance to varying degrees, depending on the agent. Patients with diabetes mellitus should be monitored more closely during therapy with estrogens and/or progestogens, and adjustments made accordingly in their antidiabetic regimen.

• Hyperlipidemias

  Moderate

  Although estrogens have generally favorable effects on plasma lipids, including increases in HDL and decreases in total cholesterol and LDL, they have also been associated with significant elevations in triglyceride levels, particularly when high dosages are used. Severe hyperlipidemia is known to sometimes cause pancreatitis. Patients with preexisting hyperlipidemia may require closer monitoring during estrogen therapy, and adjustments made accordingly in their lipid-lowering regimen.

• Liver Diseases

  Moderate

  Estrogens are primarily metabolized by the liver. Patients with impaired hepatic function may be at increased risk for adverse effects associated with estrogen administration due to decreased drug clearance. Therapy with estrogens should be administered cautiously in patients with liver disease. In addition, clinicians should be aware that estrogen therapy may affect liver function tests. Increased sulfobromophthalein retention has been reported with the use of estrogen-containing oral contraceptives and may be expected with larger doses of estrogens.

• Melanosis

  Moderate

  The use of exogenous estrogens may occasionally cause chloasma, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking combination oral contraceptives.

• Thyroid Diseases

  Moderate

  When administering estrogen and/or progestogen therapy in patients with thyroid disorders, clinicians should be aware that these hormones may affect thyroid function tests. Changes have mostly been reported with the use of combination oral contraceptives. Specifically, thyroid-binding globulin (TBG) may be increased, resulting in elevated circulating total thyroid hormone, as measured by PBI (protein-bound iodine), T4 by column or radioimmunoassay, or T3 by radioimmunoassay. Free T3 resin uptake may be decreased. On the contrary, a decrease in TBG and, consequently, thyroxine concentration, has been reported by the manufacturers of the progestin-only (norethindrone) oral contraceptives.

• Water-Electrolyte Imbalance

  Moderate

  Estrogens and progestogens may cause fluid retention, particularly when given in high dosages or for prolonged periods. Therapy with these agents should be administered cautiously in patients who have preexisting problems with excess fluid. In addition, patients with conditions that may be adversely affected by fluid accumulation, such as asthma, epilepsy, migraine, and cardiovascular or renal dysfunction, should be observed for exacerbation of their condition during estrogen and/or progestogen therapy.
